The bonus level is semi-invisible challenge, and the game continues until you top out. This mode is available only in website version. In Facebook version it was available as Holiday mode, but it's not available now.
This mode simulates classic GameBoy version of Tetris, but it's not so accurate. For example, DAS is somewhat faster, the gravity at level 15 is slower than original, and it has lock delay. Both A and B type game can be played, but B-type game doesn't have a separate leaderboard.
