Slot Machine

Slot Machine is the third Mini-game, available as soon as the Mini-games are unlocked. To pass the level you must collect 2,000 Sun, which can also be used to activate the slot machine. The machine may give you a Peashooter, a Wall-nut, a Snow Pea, a Sunflower, a Sun bonus (100 sun), or a diamond when two of a kind appear (depending on which two), or three of a plant, a Sun jackpot (500 sun), or five diamonds when there are three of a kind. Each pull costs 25 Sun.

Strategy
This Mini-game has a relatively simple strategy: just plant Peashooters, Snow Peas, and Sunflowers mixed together in the back, and create a barricade of Wall-nuts in front. You may have trouble to begin with, depending on your luck, but it gets easier the farther you get, as there are only a couple of zombie types to contend with. Eventually, there will be more and more zombies at once, so if you are trying to earn money by preventing yourself from winning and attempting to get diamonds, you may have to win so that hordes of zombies getting past your defenses will not make you lose.
