Tetrisoid is an interesting variation of classical game with original design. All this tetris elements seem to be performed on a squared notebook sheet by ordinary rolling writer. At the simplest level (Standard) we meet usual tetris, common to everyone. At Hard level the blocks get more difficult and the most difficult at Unreal level. Try to get as much scores as possible to prove that there is nothing unreal for you. Control using arrow keys. Use “Up” or Space Bar to block rotation.
