Tetrominoes fall from the top. Move them to fill complete rows. Full rows are cleared and score points.

Clearing multiple rows at once scores more. A Tetris (4 lines) gives the most points.

Use Hold to save a piece for later. You can swap once per drop.

T-Spins, S/Z-Spins and wall kicks let you rotate pieces into tight gaps. SRS kick tables enable advanced techniques like TSDs and DT Cannons.

The game speeds up every 10 lines. Survive as long as you can!
