Here's the most exciting game since the Tetris - the Tetris duo. Keep your brains twice as sharp, since this is the game with 2 Tetris games going on simultaneously brilliantly brought together. Use your arrow keys to control the falling blocks in a single game. You should use the spacebar to switch between the games. The fun begins once you move up levels and the games get sped up. You lose once either of the games go out of hand. Twice the game, twice the energy, twice the fun. Tetris Duo is one of our many Arcade Games that we publish on TheGamerStop.com.
