General Tips
- Unlimited Coins (Multiplayer Exploit): Play in the Garden Ops mode with friends, and make sure that at least two players are sunflowers. Continue playing until there are only two zombies left in a wave, and have both players standing near one another and healing. Now you can turn off your controller and go do other things while the sunflowers continue healing one another and collecting coins as the zombies attack unsuccessfully.
- Flying Cactus or Engineer: When playing as the Cactus, stand on the edge of a tallnut barricade, or the edge of a wall, and press the appropriate button to activate your drone. Fly beneath the vantage point where your Cactus is positioned and from there ascend to position the Cactus on the flying drone you are controlling. You can fly up to a roof or other high elevation, reaching areas that would otherwise be unavailable to that class. A similar technique also works as the Engineer with its drone, though not as effectively.
