Question: what are t spins in tetris 99?
Answer: In Tetris, a T-Spin describes the act of placing a T-Tetrimino into a T-Slot (i.e., a slot shaped like a T-Tetrimino), then rotating it before the piece is Locked Down. Oftentimes, this maneuver relies upon the last Tetrimino move being a rotation (not downwards or to the side).
