Tetris 64

In addition to this standard mode, the game features two unique variants: In "Giga Tetris" the player occasionally has to deal with huge blocks which break up when touching the ground. "Bio Tetris" makes use of the bio sensor accessory which was included with the game: it is clipped into the user's ear and measures the heart rate. It can be set if the game slows down or speeds up when the heart rate rises.
