Click the Tetris pieces. They will change colors as you move. Keep clicking...but remember there are two Tetris pieces, so you have to be fast.
For best results use touchscreen and full screen. Scratch is the best way to play this game because on some devices it is blocked... Tell me the Tetris Score you got in the comments. Highest Tetris score gets a shoutout on my page and a game dedicated to them.
