In this game, your Tetris stacking rhythm syncs with the music. During the rhythm section, tetrominos won't drop; you must press the hard drop key when the note aligns with the time bar. Failing to do so will cause the tetromino to break, and the "san" value will decrease. When the melody section begins, the tetrominos behave just like the shapes in a traditional Tetris game. However, the "san" value will constantly decrease, challenging you to stack shapes quickly. Should the "san" value fall below zero, a garbage line will be added, increasing the game's difficulty.
