Survival: Endless/Strategies

This is a strategy page about Survival: Endless. Feel free to add your strategies, but see the rules page first.

Building the setups


Setting up any sustainable endgame builds usually require a lot of sun. Therefore, anyone new to Survival: Endless should at least read this before venturing off to other builds. Here, the setup is used as an example is a very popular 8 Cob Cannon setup by 3C妹妹.



Start off with the following seed packets picked as shown on the diagram. Plant Sunflowers on the leftmost side of the pool. Alternate using Potato Mine and Squash to ensure the cooldown of seed packets will not be an issue when two zombies arrive in two separate lanes.



Once obtained sufficient sun, plant a Gloom-shroom in the pool. Ordinary Zombies can only walk within 1 tile of Gloom-shroom's range before dropping dead. However, Conehead Zombies can walk 3 tiles before collapsing. If the Gloom-shroom was waken up late, use Potato Mine or Squash to deal with the zombie.



Plant a Garlic on the respective lane and Pumpkin on the Gloom-shroom as soon as possible while fending off the other half of the pool with Potato Mine and Squash. Repeat the process for the second Gloom-shroom. Once that is done, focus entirely on gathering sun and planting Pumpkins and Gloom-shrooms on the pool to prepare for surprise attacks from the pool.



Once the arrival of the first Flag Zombie, expect to see Buckethead Zombies at this time. They are not an issue in the pool as long the Gloom-shrooms are protected with Pumpkins. However, if they are on land, eliminate them with Potato Mine or Squash. Be mindful that it takes the Potato Mine the same time to be armed as a zombie walking three tiles towards it.



By the time the second flag is up, the pool should have at least 4 Gloom-shrooms with Pumpkins as well as the land mostly filled with Sunflowers. If an Ambush Zombie emerges in a spot where he is not in a Gloom-shroom range, use a Squash to deal with it. If multiple Ambush Zombies appear that are not in range of a Gloom-shroom, plant a fifth Gloom-shroom to deal with them. The player is expected to have at least 3000 sun here.

The choice of seed packets for third flag and onward is based on the zombies and setup. So be sure to understand what respective seed packets should be taken to handle the zombies while developing further into the desired endgame build.

Example is shown in the gallery:

Strategy 1
Duration: About 20 flags

Seed slots needed: Nine or ten

Waves 1-2
Plants: Rake is not needed.
 * Sunflower
 * Peashooter
 * Repeater
 * Lily Pad
 * Tall-nut
 * Imitater Tall-nut
 * Spikeweed
 * Spikerock
 * Torchwood
 * Anything else

Start planting Sunflowers in the back two columns. When the first zombie comes, plant a Peashooter in that lane. When a Conehead Zombie comes, plant another Peashooter in that lane or replace it with a Repeater. Reserve three columns for your shooting plants. Plant Spikeweeds in the front two lanes when you can. Plant Tall-nuts behind them, and if you don't have it recharged use the Imitater form. Plant Torchwoods in front of the three peashooting columns. Once you have Peashooters in all 18 spots, replace them with Repeaters. The only free spaces should be the two front pool columns.

Waves 3-4
Plants: Finish planting Spikeweeds and upgrading your Peashooters to Repeaters. Upgrade your Sunflowers to Twin Sunflowers. Don't upgrade the ones on the pool; when you upgrade a Sunflower shovel one on the pool and upgrade a Lily Pad to a Cattail. You can also upgrade your Repeaters to Gatling Peas. Make sure to replace your Tall-nuts. Pumpkin the Torchwood to protect it from ambush zombies.
 * Twin Sunflower
 * Tall-nut
 * Spikeweed
 * Spikerock
 * Repeater
 * Gatling Pea
 * Cattail
 * Pumpkin
 * Imitater Pumpkin
 * Torchwood

Waves 5-6
Plants needed: You now can do something with those four empty spaces. Put a Pumpkin around a Gloom-shroom. Do the same things as in the previous waves as before.
 * Twin Sunflower
 * Pumpkin
 * Lily Pad
 * Gatling Pea
 * Cattail
 * Spikeweed
 * Spikerock
 * Coffee Bean
 * Fume-shroom
 * Gloom-shroom

If there are Digger Zombies, replace some of your Repeaters with Split Peas. If there are Zombonis or Gargantuars, make sure you have a lot of Spikerocks to stall the Gargantuars and kill the Zombonis.

Starting round (flags 1-2)
Start with Sunflowers, Cattails in the middle of the pool, Tall-nuts in front of Cattails, and 4 Cob Cannons at the back of the pool.

Flags 3-6
Add Winter Melons at the 4th column ground; Umbrella Leaves at column 5, lanes 2&5; and Gloom-shrooms at column 6, lanes 2&5. Upgrade Sunflowers to Twin Sunflowers (except column 2) to earn Sun. Every second flag of each round, 5.5 seconds after huge wave signal appears, use Ice-shroom to stop the underwater zombies from coming out.

Flags 7-10
Replace Sunflowers at column 2, rows 1&6 to Gloom-shrooms in Pumpkins for the Diggers, and to Umbrella Leaves at columns 2&5, rows 2&5 for Bungees and Catapults. If there are Gargantuars, replace Twin Sunflowers in column 3 with Spikerocks and Pumpkin the plants in column 2 for the Imps. Remove the extra Sunflowers if the sun reaches maximum (9990 sun) but keep 2 of them in column 5, rows 1&6.

Strategy 3: King Cobless
This is by far the best cobless strategy out there. No Ice-shroom needed! It'll take a few tries to set up, but it's worth it!

Minimum seed slots: 10.

Flag 1-2
Pick these plants:
 * Sunflower
 * Potato Mine
 * Lily Pad
 * Cattail
 * Repeater
 * Torchwood
 * Twin Sunflower
 * Gatling Pea
 * Pumpkin
 * Melon-pult

Plant five Sunflowers on each grass lane. When the first zombie comes, kill it with a Potato Mine. When the second one comes, save enough sun for a Cattail. Plant the Cattail on the first column. When you get the chance, plant a Twin Sunflower on one of the Sunflowers on the first column. Plant Repeaters in the third/fourth column from the right. When a Buckethead Zombie comes, plant a Torchwood on the second lane from the right, or Gatling Pea if you have it, on the same lane as it. If a Buckethead Zombie appears on the pool, plant another Cattail and, if you have it, a Melon-pult on the same lane. By the end, it should look like this: TSF = Twin Sunflower

SF = Sunflower

C = Cattail

MP = Melon-pult

R = Repeater/Gatling Pea

t = Torchwood

Underlined = On Lily Pad.

Bold/I' talics  = Pumpkin

3-4
Choose these plants: Plant Repeaters in front of your other Repeaters. Upgrade the Melon-pults to Winter Melons. Place 3 new Melon-pults in front of your Winter Melons. Do NOT upgrades those Melon-pults to Winter Melons. Your sun is vital. Place Sunflowers in front of your Melon-pults. Plant Gloom-shrooms on the second column from the right in the pool. Pumpkin them. It is good to plant them on the second from the right because of Dolphin Rider Zombies. Upgrade the Sunflowers on the pool to Twin Sunflowers. Now it should look like this: WM = Winter Melon
 * Lily Pad
 * Repeater
 * Pumpkin
 * Winter Melon
 * Melon-pult
 * Sunflower
 * Twin Sunflower
 * Fume-shroom
 * Gloom Shroom
 * Coffee Bean

GS = Gloom-shroom

This strategy is not finished. It will be later.

Strategy 4: Basic 10 Cob cannon Strategy
It may cost a LOT of sun, but it can last very long, and can kill the zombies rapidly, but it still may not work as you want. It also needs 10 seed slots, which is very expensive on the store (I survived 74 flags with it, but I didn't use it correctly)

Flag 1-2
(Underlined = Extra seed (unneeded)) (Rake not needed)
 * Lily Pad = Underlined (on strategy board)
 * Cob Cannon = CB (its downgrade too)
 * Melon-pult = MP
 * Winter Melon = WM
 * Pumpkin=PK
 * Cattail=CT
 * Twin Sunflower = TW (its downgrade too)
 * Imitater Sunflower = IS
 * Potato Mine = PM

First, plant Sunflowers and its Imitater counterpart. Then, if you see a zombie, plant a Potato Mine 4 squares in front of the zombie. Then plant a Lily Pad in the middle upper row of the Pool. If you can, upgrade it into a Cattail.

Then, plant Cob Cannons behind the Cattail. Try to plant under the first Cob Cannons more Cobs, but do not plant before Flag 3 Cobs in front of them, (okay, if you can shoot the Ambush Zombies before they eat your Cobs, Do it! feel free to do it) then, plant Cob Cannons on the land, 4 squares in front of the house (detailed placing is in the strategy board), then plant Melon-pults behind them.

Strategy board: ( NO = do not place anything there) (PK with other plant shortening (like PKWM) means that you have to place the plant INSIDE the Pumpkin)

PK  PK  PK  PKWM   CB TW  TW  IS

PK  PK  PK  PKWM   CB  IS  IS  TW

CB  CB   PKCT  NO  NO  PKTW  PKTW  PKIS

(Same as above)

(Same as the Land part above)

(Same as Above) It is not finished yet. I will work on it, when I do have time.

Strategy 5: Star856190's Strategy
This is PowerStar856190's strategy. It has survived 103 flags. Some plants are optional. All plants, except Spikerocks and optional Fume-shrooms are Pumpkined.

 * Cob Cannon
 * Spikerock
 * Winter Melon
 * Cattail
 * Ice-shroom

You can use mostly anything else. If somebody can add the grid template, I'd like that. :)
 * Spikerock

 * Coffee Bean
 * Umbrella Leaf(When Bungees and Catapult Zombies come)

WinterMagnet's No losing plants strategy
Just do the following template

Do this template. Make sure all plants on ground are in a Flower Pot and protected with a Pumpkin.
 * SR WM ( Jalapeno safe area )
 * SR GP UL
 * CT IS IS TS TN ( Insert Doom-shroom here )
 * CT IS IS TS TN ( Insert Doom-shroom here )
 * SR GP UL
 * SR WM ( Jalapeno safe area )

(index)

GP = Gatling Pea

UL = Umbrella Leaf

WM = Winter Melon

SP = Spikerock

IS = Ice-shroom

TN = Tall-nut

TS = Twin Sunflower

Once done, you must do this before flag 20 ( Check that ).

Wait to a flag with Ladder Zombies and no vehicle zombies but Catapult Zombies, make sure there is no Jacks.

Keep directing them away from the water using Garlics, 1 Winter Melon is enough.

Assuming you done, here is what the map must look like, remember to switch GPs to WMs.

SR(WM)(FS)(FS)

SR(WM)(UL) CC

CT IS IS TS

CT IS IS TS

SR(WM)(UL) CC

SR(WM)(FS)(FS)

= laddered plants CC = Cob Cannon FS = Sleeping Fume-shrooms

Once done, put Gloom-shrooms in place of the Cobs, and there are no Jalapeno safe areas now.

Don't forget to put Cobs in the water in place of the top 2 Ice-shrooms, you ain't wanting 4, right?

Once done, wake them all up in the water your going to change ( Before setup 3 )

SR(WM)(FS)(FS)[UL]

CT IS IS TS TS TN

SR(WM)(UL)(GS)[UL]

TN = Tall-nut

[] = UNLADDERED PUMPKINS

Wait to a flag that meets requirements

NO Dolphin Riders / Snorkel Zombies

Above flag 45

No Zombonis

No Football Zombies

No Jacks

No Pogos

So put Gloom-shrooms, at the remaining part of the pool, but remember.

You will put Snow Pea and Gold Magnet

On the back put 1 snow pea in the bottom part

and the front gold magnet.

Once done, do the following. Let's say you ended up in 68.

Puff shroom

Coffee bean

Ice shroom

Imitater Cherry Bomb

Cherry Bomb

Squash

Doom-shroom

Lily pad

Tangle kelp

Sun-shroom

Strategy 12: How to play with the Magnet-shroom combo ( By WinterMagnet )
Plants :

Winter Melon

Umbrella Leaf

Gloom-Shroom

Twin Sunflower

Gatling Pea

Pumpkin

Obviously, Magnet-shroom.

Please note that upgrades' downgrade

Fill the pool with Twin sunflowers except for the last 5 blocks.in the 3rd and 4th place a gloom-shroom and the rest is empty

Put Magnet-shrooms at the most front. Don't worry about it. Pumpkin it. Put the other parts behind it with 3 winter melons far from the pool and another 2 near them. (Yes, it is 2 and not 3, 3 is for the far)

put Gloom-shrooms near it and put a Fume-shroom at the most top part.

Then put Gatling peas (Optional, However it works best with Magnet-shroom) and then place instant everywhere. The pool must be safe. Like the ground. Enjoy the defense!

Strategy 13: Fairly simple survival strategy (By SplatterAndDodge)
This one is fairly simple, but I hate to inform it's not the most effective. It should last at least 20 flags.

Fill the back 2 rows with Sunflowers. Use Cabbage and Kernel-pults for the first wave or so. Plant Melon-pults if you can afford them. If not, use Repeaters for now and replace them with Melon-pults over time

Turn the Melon-pults in rows 2 and 5 into Winter Melons. Also, upgrade your sunflowers to Twin Sunflowers. Plant pumpkins around them in case of miner zombies.

Replace the sunflowers in column 2, Rows 2, 3, 4 and 5. In rows 2 and 5, place Umbrella Leafs. In Rows 3 and 4, place Cattails. Replace the Cabbage-pults with Cattails in the pool. Turn the ones on land into Kernel-pults, and eventually Cob Cannons. Also replace the Kernel-pults in the pool with more Cattails.

In the 4th column closest to the front, plant Tall-nuts. Place them in pumpkins when you can. Place Gloom-shrooms, again in pumpkins, in the column in front of then. In the remaining 2 columns, fill the ones on land with Spikerock and the ones in the pool with Gloom-Shrooms in pumpkins.

Here's what it should look like when completed

TS/P TS CC cc WM/P TN/P SR SR

TS/P U CC cc WI/P/ TN/P SR SR

WARNING: Imps and Digger Zombies are dangerous with this strategy. Use with caution.

Strategy 14: Winter Melon Build (By BaronBlastoise)
This one is quite simple, use a lot of the strongest plant in the game, Winter Melon.

The strategy has lasted 30 waves before.

I'll be improving this as I try out different strategies.

Plants Needed (Final Build)
The final build will be 2 columns of Twin Sunflowers with Umbrella Leafs for Catapult Zombies and Bungee Zombies. Tall-nuts should be in the front, leaving a columns for Spikerocks. Everything in between should be Winter Melons. In the pool, There are the 2 columns of Twin Sunflowers, then 4 Cattails, 6 Winter Melons, with Tall-nuts in the front, leaving 1 column empty (otherwise Dolphin Rider Zombies will not be blocked, which isn't good for the starting waves, but not too big of a concern for the later waves. Then you can use it for Doom-shrooms).
 * Twin Sunflower
 * Umbrella Leaf
 * Winter Melon
 * Cattail
 * Tall-nut
 * Spikerock
 * Pumpkin
 * Spikeweed (for repairs, as Gargantuars, Zombonis, and Catapult Zombies will take out your Spikerocks)
 * Lily Pad (for repairs)
 * Melon-pult (for repairs)
 * You can choose bombs or other instant kills in available slots for emergencies. You can also Imitate Pumpkins or Spikeweed.

Everything should ultimately have Pumpkins, except Spikerocks, but since that would a very long time to set up, you should prioritize: You should be able to replace Spikerocks very fast when they are destroyed. This is quite possible as everything will be moving very slow because of your Winter Melons, and the biggest threat, Gargantuars, already move slow.
 * The 1st column, the back Twin Sunflowers, for Digger Zombie s
 * The 3rd and 4th columns, as that's usually where Imps land (if you are doing everything correctly)
 * The Winter Melons in the pool, as zombies will rise in the pool during waves
 * The 8th column, before the Tall-nuts, for Backup Dancers that may pass your Tall-nuts when spawned.

Setting Up
In the starting rounds, before you can afford the final build, set up like this:
 * 1) Plant some Sunflowers (depending on if you have a Garden Rake or not), at this point a zombie should appear, plant a Peashooter in the 3rd column (this is vital as you'll need 2 columns of Sunflowers). Continue planting Peashooters where zombies appear and planting Sunflowers when you can afford it. When stronger zombies appear, you should have enough sun (especially if you had rake) to plant Wall-nuts, Tall-nuts, or Melon-pults (replacing Melon-pults are preferred, if you have enough sun).
 * 2) After 2 flags, you should have a column of Melon-pults. Start planting Tall-nuts where they should be in the final build, plant more Melon-pults, upgrade Melon-pults to Winter Melons (you should only upgrade 1 until you have full Melon-pults). You should upgrade your Sunflowers to Twin Sunflowers AS SOON AS YOU CAN! This is very important. Replace Sunflowers on row 2 and 5 with Umbrella Leafs when Catapult Zombies and/or Bungee Zombies start appearing. Bungee Zombies won't be too much of a threat to your Melon s as they will probably be killed, and if they aren't, you should be able to replace Melon s pretty quickly.
 * 3) Plant Pumpkins, prioritizing the back (when Digger Zombies appear), the middle section of the pool (for those zombies that rise in the middle of you pool), the 3rd and 4th columns, for Imps that are thrown into your defenses, and the column before your Tall-nuts for Backup Dancers that are spawned there.
 * 4) Spikerocks should be planted before Gargantuars, Zombonis, and Catapult Zombies appear, since it'll be safer to plant earlier and you'll be prepared. Otherwise, you'll be frantically planting them before a flag and since Spikerock loads very slow, may not be able to plant them in time and thus your defenses will be heavily damaged.

Final Build Diagram
TS = Twin Sunflower

UL = Umbrella Leaf

WM = Winter Melon

CT = Cattail

TN = Tall-nut

SR = Spikerock

(Pumpkins not labeled)

Switching to the Armageddon Method
As you get farther, if your defenses ever get destroyed beyond repair, you can switch to the Armageddon Method as a last resort to last a few more waves. Somethings though, especially early on, you'd be surprised at what one can recover from, so use this only when you are definitely destroyed beyond repair.

Choose all the instant kills you can:
 * Doom-shroom (with Coffee Bean), this is the best instant kill, used sparingly, as it loads very slow and creates a crater, during waves to wipe out most of the wave and most importantly weakening Gargantuars and Giga-gargantuars. Planting these in the pool yields maximum damage. You should probably imitate this to effectively double its loading speed
 * Cherry Bomb, another good instant kill when Doom-shroom is loading
 * Jalapeno, good when a row of zombies are going to take out a mower or eat your brains
 * Ice-shroom, freezes all zombies so that your remaining defenses can attack them or your other bombs can load
 * Squash, not the best as it only kills a few zombies, so only use it to prevent a game over.
 * Pumpkin, Spikeweed, and Spikerock to stall zombies so that you remaining defenses can attack them or your other bombs can load.

Options
Feel free to add your own ideas that worked, please put explanations.
 * Magnet-shroom can be put in the 7th column instead of Winter Melons to weaken a wide variety of zombies, remove ladders, or stop Digger Zombies.
 * Push the Tall-nuts in the pool up a column and plant more Winter Melons. Make sure these have Pumpkins in case of Dolphin Rider Zombies.

Tips
Feel free to add your own ideas that worked, please put explanations.
 * Choose instant kill (most preferably Doom-shroom) to weaken Gargantuars and especially Giga-gargantuars along with a big chunk of a wave of zombies.
 * Use Imitater for Spikeweed or Pumpkin to repair you defense quicker.

Strategy for Android version
Note: This is for android version 6.0.0 of this game, so I will tell about them.

Difference to PC version
This version has little difference to PC version, but it has very big changes in Survival: Endless.

Digger Zombie
The Digger Zombie pops up on ground little back, and for that, with 2 Gloom-shrooms(1,2/5,6), you must be able to kill Digger Zombies without hurting any plants! It means you don't have to repair your Pumpkin at the first column! (but if Imps are thrown to first column, and.....)

Nine Seed slots
You can't buy the 10th seed slot, but mallet is instead of the tenth one. Mallet is useful, or wasteful by how you use it.
 * You will think the mallet is same as the one that you saw at an minigame, and it is correct. You can use mallet at first two flags with your first defencing plants. Or it will be useful for killing Giga-gargantuar waves, and you should tap the screen rapidly with thinking that this tapping is just for Giga-gargantuars.
 * You need to notice the refreshing time for mallet.

Every 2 flags
The Zombie will appear at 5th column too! (but rarely) So the limit of placing your Cob Cannons at water is 4, so you can't have more Cob Cannons.

Strategy 15: Unmasked Badger
Duration: 100 flags and more

Note: I do not own this strategy all, just sharing it, all credits go to DianAra Before I begin to explain the strategy the Garden Rake MUST be bought, as well as all the upgrade plants, the imitator and the 10 seed slots.

Plants

 * Sunflower
 * Twin Sunflower
 * Lily Pad
 * Cattail
 * Coffee Bean
 * Fume-shroom
 * Gloom-shroom
 * Kernel-pult
 * Pumpkin
 * Imitator Pumpkin

Part 1
Start off by putting down 4 Sunflowers in the top left corner of the lawn, no more than that, ignore the first zombie, the rake will take care of him once the second zombie appears collect 250 sun from your 4 sunflowers and place down a lily pad on the fifth column of the pool (counting from the left) and upgrade it to a cattail to take care of that second zombie.

Part 2
Completely fill up columns 1,2,3 and 4 with sunflowers, and the land squares on column 5 with sunflowers, your going to need the mass amount of sun,meanwhile, once Cattail has recharged, and sunflower is still recharging put down another Cattail on column 5, put down kernel-pults on column 6 on the land squares only, then pumpkin the Cattails and the Kernel-pults do this while still planting sunflowers on the left rows.Now place down 2 Twin Sunflowers in Column 6 in the pool squares only,pumpkin them (from now on every newly placed plant must get pumpkined I won't say it again) and also upgrade the sunflowers on column 4 on rows 2 and 5 to twin sunflowers, remember while still planting sunflowers in the left rows.Now to get the 6 Gloom setup in, place Fume-shrooms in columns 7,8 and 9 in the pool squares only and upgrade them all to Gloom-shrooms and then wake them all up, once again still remembering to plant sunflowers on the left rows after this first wave the setup should look something like this: Key:
 * S= Sunflower
 * Ts= Twin Sunflower
 * Gs= Gloom-shroom
 * Ct= Cattail
 * K= Kernel-pult
 * = Pumpkin or Imitator Pumpkin

Plants

 * Melon-pult
 * Winter Melon
 * Kernel-pult
 * Cob Cannon
 * Coffee Bean
 * Fume-shroom
 * Gloom-shroom
 * Lily Pad
 * Pumpkin
 * Imitator Pumpkin

Strategy
Time for heavy weapons, dig up sunflowers in column 3 on rows 1 and 6 and replace them with Winter Melons, in the meantime also dig up sunflowers in column 3 and 4 in the pool squares only and replace them with 2 Cob Cannons, after those are done dig up sunflowers in column 1 on rows 2 and 5 and replace them with Winter Melons, in the meantime dig up all remaining sunflowers in the pool squares only and replace the, with 2 more cob cannons. Digger zombies may be arriving in later waves or sooner so dig up the remaining sunflowers in column 1 and replace them with Gloom-shrooms.In the end of the wave the setup should look like this: Key:
 * Wm= Winter Melon
 * CC= Cob Cannon

Plants

 * Melon-pult
 * Winter Melon
 * Kernel-pult
 * Cob Cannon
 * Coffee Bean
 * Fume-shroom
 * Gloom-shroom
 * Pumpkin
 * Cherry Bomb
 * Imitator Pumpkin

Strategy
Time for part 2 of heavy weapons. Dig the remaining sunflowers in column 4 (not the twin sunflowers) and replace them with Winter Melons meanwhile, dig up sunflowers on column 5 on rows 2 and 5 and dig up the pumpkins on the kernel-pults only, then place in 2 more Cob Cannons on rows 2 and 5 taking up columns 5 and 6. Then dig up the remaining sunflowers on column 3 and replace them with more Winter Melons meanwhile, dig up the remaining sunflowers on column 5 and place down 2 more Cob Cannons on rows 1 and 6 taking up columns 5 and 6. There is a high chance that Gargs are coming so dig up the sunflowers on column 2 rows 2 and 5 and replace them with Gloom-shrooms. The end of wave setup should look like this

Plants

 * Umbrella Leaf
 * Spikeweed
 * Spikerock
 * Pumpkin
 * Imitator Pumpkin
 * Squash
 * Cherry Bomb
 * Jalapeno
 * Coffee Bean
 * Ice-shroom

Strategy
There isn't much left now, dig up the 2 remaining sunflowers left on the lawn and replace them with Umbrella leafs and then place Spikerocks on column 7 on the land squares only and you should be done with the entire setup, here is what the final thing should look like

Wave 5 onward (flag 9 onward)
With the setup now complete I will explain the plants now needed and how to fire the Cobs

Plants

 * Spikeweed
 * Spikerock
 * Cherry Bomb
 * Squash
 * Jalapeno
 * Pumpkin
 * Coffee Bean
 * Ice-shroom
 * Doom-shroom
 * Imitater Pumpkin or Imitator Cherry Bomb

When and where to fire the Cob Cannons
With the current setup you get 8 Cob Cannons with 4 strikes on each side before the next reload, you want to fire the Cobs as late as possible always on rows 2 and 5 on column 8 and sometimes column 7 and 9, if all the Cobs are reloading and you need to make a strike then use an instant kill Cherry Bomb, Squash and Jalapeno in that area, make sure to regularly replace pumpkins with new ones. Depending on your skill you may make it to flag 100. Thanks for reading this strategy.

Testing
Strategy was broken by Giga-gangantuars in the 22th flag.

Flags survived: 24 (by Pole Vaulting Zombie).

Forecast on normal PC versions: 15–20 flags if 9 slots; 20–25 if 10.

Strategy 17: Perfect Strategy
I have made a Survival Endless build that made me survive 800 flags. If you want to get here, read my strategy.

I was keeping going, 8 cobs never died.

This is the best strategy to survive lots of flags, because the Cob Cannons can kill the Gargantuars, the Spikerock can kill vehicles, and the Gloom-shrooms and Winter Melons can kill almost all zombies, and Cattails can pop balloons. Hence, only the Giga-gargantuar can survive. You will need a lot of sun to build this setup, as it has a lot of awesome, powerful plants.

Flags 1-2: Required plants Then, you can choose any plants.
 * Sunflower
 * Twin Sunflower
 * Lily Pad
 * Melon-pult
 * Squash
 * Potato Mine
 * Tangle Kelp
 * Umbrella Leaf
 * Jalapeno
 * Cherry Bomb

My build: Key: UL = umbrella leaf

TS = twin sunflowers

G-s = gloom-shroom

WM = winter melon

CC = cob cannon (half)

Ct = cattail

T-n = tall-nut

Sr = spikerock

. = not pumpkined

Strategy 18: Superblockma's Super Sun Strategy
''' This strategy does not always work. ''' You will need rake

Flag 1
Plants needed
 * Sunflower
 * Twin Sunflower
 * Repeater
 * Gatling Pea
 * Potato Mine
 * Imitator Potato Mine
 * Lily Pad

Then you can pick 2 tspp (Temporary solution to permnent problem) plants (Squash, Jalapeno, Cherry Bomb ext.) If you get the reference your awesome.
 * Tangle Kelp

First you should place two columns of sunflowers and turn them into twin sunflowers(this might take flags 3-4 to finish) while killing zombies with Potato Mines and slowly planting repeaters and upgrading them to Gatling Peas.

After that the board should look something like this.

S= Sunflower

TS= Twin Sunflower

R= Repeater

GP= Gatling Pea

PM= Potato Mine

_= Lily Pad

Flag 3
You now need the same plants except all tspps except squash gone and replaced with Chomper, Tall-nut, Pumpkin, Torchwood and Catails. PUT PUMPKINS AROUND EVERY PLANT
 * FINISH UP UPGRADING PLANTS

Place Torchwoods in front of the repeaters/Gatling peas

In front of the torchwoods in the water place catails

If you finish this start placing tall-nuts in the seventh column and place chompers behind them.

The board should look the same but with torchwoods catails chompers and tall-nuts

from 5-forever
from waves 5 to infinity you need to place fume shrooms in column 1 row 2 and row 5.

you also need to place spikerocks in column 8&9 rows 1,2,5 and 6

leave the column 5 rows that are blank for tspps and the water rows' empty squares for tspps

 REMEMBER: PUMPKIN EVERYTHING ASAP EVEN IF IT MEANS BRINGING IN A IMITATOR PUMPKIN 

Strategy 19: Leonardo G.'s Gloomy Strategy
This Survival: Endless strategy has gotten me to 35 flags, but then I restarted it since I didn't want to go any further (I usually only play Survival: Endless until I get 50,000 coins, buy a Zen Garden plant, then restart and repeat).

Flag 1
Since I play on the mobile version, you can bring an extra plant if you have the PC version due to 10 seed slots not being available on my version.

Here are the required plants: Plant two columns of Sunflowers and plant down Twin Sunflowers whenever you have the chance. Use Potato Mines to kill zombies. Rakes, in my opinion, are not significantly helpful, as they only save you 25 sun, but go ahead and purchase them if you want to. Plant Melon-pults in front of the Sunflowers and upgrade them to Winter Melons when you can, but focus on planting Fume-shrooms and upgrading them to Gloom-shrooms. The purpose of bringing Lily Pads are obvious.
 * Sunflower
 * Twin Sunflower
 * Melon-pult
 * Winter-melon
 * Lily Pad
 * Potato Mine
 * Fume-shroom
 * Gloom-shroom
 * Coffee Bean
 * (PC-exclusive slot) Instant-use plant

Here's what you should have for the first flag. (Not the final product.)

T/S = Twin Sunflower/Sunflower

W/M = Winter Melon/Melon-pult

G/S = Gloom-shroom/Fume-shroom

E = Empty

Flag 2
Here are the required plants: You will need to start planting down Kernel-pults and then upgrading them to Cob Cannons - two of the Cob Cannons are needed for this strategy. Then, place down two Fume-shrooms and later upgrade them to Gloom-shrooms, each plant being in front of a separate Cob Cannon. Place down two Umbrella Leaves, one of them being above the 3rd lane and in the 2nd column, another being below the 4th lane and in the 2nd column. Continue upgrading the Sunflowers to Twin Sunflowers. Start putting Pumpkins on the plants, especially on the Gloom-shrooms in the pool lanes.
 * Umbrella Leaf
 * Kernel-pult
 * Cob Cannon
 * Fume-shroom
 * Gloom-shroom
 * Twin Sunflower
 * (If not finished with W/M, bring Winter Melon; if finished, bring Instant-use plant)
 * Pumpkin
 * Coffee Bean
 * (PC-exclusive slot) Instant-use plant

Here's what you should have for the second flag.

C/K = Cob Cannon/Kernel-pult

UL = Umbrella Leaf

Flag 3
Here are the required plants: You will need to start planting down Fume-shrooms and upgrading them to Gloom-shrooms in the 2nd and 4th lanes, behind the Umbrella Leaves. Finish any Cob Cannons, Twin Sunflowers, or Gloom-shrooms you need to. Next, plant down two Winter Melons on the 1st and 5th lane each behind the Winter Melon in the 3rd column. (One Winter Melon goes behind the 3rd column Winter Melon, another one behind the one that's behind the 3rd column Winter Melon - it'll make sense in the visual representation below, it just sounds confusing when said through text.) Besides that, you need to plant down Pumpkins on any plant; however, planting down Pumpkins on plants behind the Cob Cannon in the pool is not needed, and if you plan on doing that, that's best saved for last, as the lanes outside of the pool will have Imps thrown onto the plants by Gargantuars, and they need to be protected with Pumpkins. You should bring along Imitater on Pumpkin, as you can plant down more Pumpkins faster to decrease the chance of Imps eating your plants.
 * Gloom-shroom
 * Fume-shroom
 * (If not done with T/S, bring Twin Sunflower; if finished, bring Instant-use plant)
 * (If not done with C/K, bring Cob Cannon; if finished, bring Instant-use plant)
 * Pumpkin
 * (Imitater on Pumpkin is suggested, but not required)
 * Instant-use plant
 * Instant-use plant
 * Coffee Bean
 * (PC-exclusive slot) Instant-use plant

Here's what you should have for the third flag, and it's also the final product.

Flags 8 through...basically infinity
Here are the required plants: We skipped to the 8th flag, because, really, that's probably more than enough time to set up your Gloom-shrooms. If it's not, then make room for two seed slots for Fume-shroom and Gloom-shroom. If you've set up all of the Fume-shrooms but haven't upgraded them all to Gloom-shrooms, then, well, use common sense; make room for only one seed slot for the Gloom-shroom. Blover is a requirement for Balloon Zombies; sure, you could use Cacti, but it's a bit hard to keep them alive, especially when Giga-gargantuars appear in the 2nd and 4th lane. Also, Balloon Zombies appear in the pool lanes, so you'll have trouble with that since every tile is occupied in those lanes.
 * Blover
 * Instant-use plant
 * Instant-use plant
 * Instant-use plant
 * Instant-use plant
 * Instant-use plant
 * Coffee Bean (for Doom-shroom, Ice-shroom, etc...)
 * Pumpkin
 * Imitater on Pumpkin
 * (PC-exclusive slot) Plant of your choice

Cob Cannons and instant-use plants should be used for Gargantuars and Giga-gargantuars. Spikeweeds and Spikerocks are considerable, as it takes several hits for Zombonis and Gargantuars to destroy them, and they provide extra damage to zombies. Combine that with the large amount of Gloom-shrooms, and even Giga-gargantuars will have trouble destroying your defenses. You may be surprised, but you can manage to get 9990 sun with only four Twin Sunflowers. I did, so I don't doubt you can, too.

Keep on using the Cob Cannons and Instant use plants, and you can get a high score. If you're too overwhelmed, (say, you're low on sun and there's a lot of Giga-gargantuars) go ahead and buy mallets!

Strategy 20: Don't Pea in the Pool
Duration: About 200 flags.

This is the best strategy to survive lots of flags, because the Cob Cannons can kill the Gargantuars, the Spikerock can damage vehicles, and the Gloom-shrooms and Winter Melons can kill almost all zombies. You will need a lot of sun to build this setup, as it has a lot of awesome, powerful plants.

Required plants: Then, you can choose any plants.
