Tet Walls - Version 1.1 A fun and unique Tetris game with 8 puzzle pieces. All the standard ones are included and even some different designed ones. Each level the game will speed up and throw you a large funky piece to make it more difficult. Every so often you will receive a lightning bolt bonus that when engaged will fry all the blocks in its path while moving upwards. Enjoy 10 randomly played smooth music tracks while making those rows of lines. Very addictive.
