Twistwris is a new game for iPhone that puts an exciting twist on the classic game of Tetris. The game is played in an extra dimension, making it both familiar and different at the same time. The goal of the game is to survive as long as possible by clearing complete rows of blocks from around the cylinder. The game becomes progressively more challenging as the player advances through the levels.

One of the unique features of Twistwris is that the player can rotate the falling shape and spin the cylinder to manipulate its position and orientation on the cylinder surface. The game ends when a new shape materializes over an already existing block. With its exciting gameplay and challenging levels, Twistwris is sure to keep players entertained for hours on end.
