Tetris Black

Tetris Black is a Tetris game for Japanese mobile phones.

Game Modes

 * Tetris: Tetris Worlds style marathon mode, with Tetris DS style scoring system. Like to TDS, T-Spin without any wall kicks will award more points. The game ends in level 15. You can still continue game beyond level 15, but clearing lines will not give you any points. (Soft drop still gives you points, however)
 * 40Lines: 40 lines time attack mode.
 * Ultra2min: 2 minutes score attack mode.
 * Black: Endless mode. Gravity is fixed at 7G, which is same as level 15 in other modes.

Super T-Spin
Sometimes, a cyan T tetromino will appear. (The rate is unknown) If you do a T-Spin with this, it will award twice points.
