Torus Free app for iPhone and iPad
Kill time with the amazingly addictive Torus. Arrange the falling blocks into rings around the base to clear each line. Play in three different game modes; Traditional - clear as lines as the blocks fall, Garbage Collection - start the level with a mangled board that you are left to clear (very challenging), Time Attack - play against the clock to see how many lines you can clear. You can hide the torus base and the shadow drop via the options panel to change the style and skill level of the game.
