Topple is a highly addicting puzzle game for the iPhone and iPod Touch. The object of Topple is to pile up the cartoon blocks that you're given as high as you possibly can within the time limit. Unfortunately, it's not as simple as it sounds due to the fact that these blocks aren't exactly flat and adhere to gravity.
You're given one block at a time to place on the surface of the level. The first few levels do have a flat surface, but that changes rather quickly. You can use two fingers to rotate any of the blocks before they hit the ground so you can stack them together in your attempt to hit both the goal and the bonus lines.
You get more points by dropping the blocks from higher up and you lose points for moving them around once they've been placed.
If your tower starts to tip, you can use the accelerometer to counter balance the fall as you continue to stack your way to the top. You can toss up to 4 blocks off the screen without ending the game. This can help when you get awkward shaped ones you just can't use.
The artwork in Topple is excellent. The backgrounds have a similar feel to the art in the TV show Samurai Jack while the blocks have a SpongeBob SquarePants/Ren and Stimpy style. This is a very addicting game and has multiple levels, achievements, and a free play mode to keep you entertained for awhile.
