T-Block
Vital statistics
Type	Tetromino
Reflection	None
Rotations	4
Maximum lines cleared	2 (3 in some games)

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 twist will earn the player a bonus of some kind. 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 a T-Spin triple.
