Get all the trophies in Mini-Games, Puzzle, and Survival modes.
The achievements are displayed as an underground list. Scroll through the list and keep going down to see various hidden objects including a zombie, the bookworm from Bookworm, jewels from Bejeweled, a unicorn fossil, and finally Chinese zombies staring back down the hole.
Disable full screen mode. Go to your zen garden. After feeding the plants, it will normally take thirty minutes to feed them again. To feed them all, change the system time to an earlier value. This will increase their growth.
To kill Bungees, use Chompers, Squash, Ice Shroom, Jalapeno, or an Umbrella Plant.
If you do not like the cards from Crazy Dave, exit the game and restart. The cards will change randomly.
When there are Pole Vaulters, pick a Walnut and a Chomper and make sure you can dig up plants and have lots of sun.. Put down a Walnut and a Chomper behind it. The Pole Vaulter will go over the Walnut and straight into the Chomper. Then, dig up the Chomper and he is gone.
