Line clear

Related terms

• Single →

  One row removed by a placement. A Single can extend a combo or repair the surface; an ordinary non-spin Single commonly breaks B2B.

• Double →

  Two rows removed by one placement. A T-spin Double adds spin recognition to the same two-line count.

• Triple →

  Three rows cleared by one placement. An ordinary Triple differs from a T-spin Triple; equal line counts do not imply equal score or attack.

• Tetris →

  Four rows cleared by one placement, normally using a vertical I. The name also refers to the game itself. A Tetris can leave many blocks behind, while a Perfect Clear leaves none.
