A T-Block is a tetromino shaped like the letter "T". It is a highly adaptable tetromino, which can be used to even out a variety of stack shapes. In many Tetris games, it is the only piece with which doing a spin will earn the player 100/200/300/400/800/1,200/1,600/1,800/2,400 points for doing so. Although in most games it can only clear up to two lines at once, some games that use SRS (Tetris DS in particular) can allow a T-Block to rotate and wall kick in very unusual ways, enabling the player to create the T-Spin triple(s)/Back to Back T-Spin Triple(s).
