Lucky Spin

Strategy
This could be the hardest achievement (After Alive and Planting) because luck plays a big part in getting the achievement. Some people need to finish Slot Machine mini-game more than 100 times to get it. However, there are ways you can maximize your chances of getting lucky.


 * Constantly spin: Spin and spin again immediately after each spin finishes. Do this before collecting or planting prizes, they will stay on screen for a while before disappearing. This will maximize the number of spins during the game.


 * Stay in the "almost there!" range for as long as possible: From the beginning of the game, plan for a long-term strategy. Use multiple columns of Wall-nuts to the far right, a couple of columns of Sunflowers on the far left, and fill up the rest of the columns with Peashooting Plants (making sure to have at least one Snow Pea per row). Then, when you reach approximately 1800 sun, only collect sun to replace the sun you're losing each spin. This allows you to continue playing for longer, maximizing the number of spins in the game and the number of drops from the zombies. Eventually a large wave of zombies will overcome your defenses. At this point, start collecting sun again to finish the game before you lose.


 * Losing is an Option: If you are not keen on winning, is this another Option: Put your sunflowers to the right as part of your passive defense. By the time the waves of Zombies are getting bigger, you'll have enough sun to constantly spin, so you don't really need these happy flowers anymore. That way your shooters can work longer, and even if they have done their Job, and the next wave is going to be your doom, you can still spin. But to keep your hopes low: I've played that Level far more than 100 times, and I still don't have the trophy...

Trivia

 * Single diamonds commonly appear in spins, but pairs or triplets are extremely rare and hard to get.
