Game Boy Color update of the classic puzzle game. You are presented with a screen that slowly fills up with Tetrads - shapes made up of four blocks. You have to move and rotate the blocks to make rows across the screen. Once a row is completed it will vanish. As you progress, the blocks will fall faster, and as soon as they hit the top of the screen the game is over.
There are several game modes and options, but the aim in them all is to get the highest score or the fastest time. You can now save your name and high scores to the cart, or play as a guest.
