YouCube is a 4-player Tetris game. The Tetris blocks which normally fall down will have to be built by hand and checked by the computer first. If the blocks are built correct the blocks can be positioned by jumping on one of the four huge buttons (left, right, down and rotate). If the block is not built correctly, it will fall down and a new block has to be built. The time to build the blocks will increase during the game and the blocks will fall faster and faster!!
