How to use
- Press Start or the Space bar to drop the first block.
- Move with ← →, rotate with ↑ or Z/X, and press Space to hard drop. On a phone, use the buttons below the board.
- Fill a whole row with no gaps to clear it. Clearing several rows at once scores more.
- Press C to hold a block for later. Every 10 lines you level up and blocks fall faster.
