Torus 3D

As far as Tetris goes, most variations look quite similar. You're usually looking at a "wall" of bricks directly from the front. Torus 3D takes that notion and throws it away; as you might have guessed from the name (or screenshot), this Tetris clone is played on a ring-like 3D surface.

Key features:
♥ 3D effect Tetris-like game
♥ Three game modes
♥ Time attack game mode is available
♥ Garbage game mode is available
♥ Gesture control
♥ Scores can be shared to facebook
♥ 100% Free

How to Play:
You rotate the ring itself with gesture or the keypad, while a Tetris-like piece slowly descends from the top. As soon as you make a solid line, it disappears.

Tips:
Not all pieces are Tetris-like; some of them wouldn't really work with a regular Tetris game but are a good fit for Torus' 3D format.
