About Tetris
Arrange seven kinds of falling tetrominoes into complete horizontal rows. Use the ghost piece to judge a landing, the next queue to plan, and Hold to save a piece for later. Rotate in either direction, soft-drop for precision, or hard-drop to lock a piece immediately. Line clears increase your score and eventually the falling speed. Choose your difficulty before a run. Watch the next queue, keep the surface level, and save a useful piece in Hold.
