About Tetris

Tetris

Classic block-stacking puzzle game.

Stack falling tetrominoes to complete horizontal lines. Completed lines are cleared for points. The game speeds up as you level up.

Keep a piece in reserve with Hold (C or Shift, once per drop), plan ahead with the five-piece preview and the ghost piece, and slide or spin a landed piece for half a second before it locks (up to 15 moves). Pieces come from a shuffled bag of all seven shapes and rotate with SRS wall kicks. Soft drop scores 1 point per row, hard drop 2.
