How do I play?

Swipe on the board. Every piece slides in that direction until it hits a wall or another piece. Fill a full row or column to clear it. After each move, the next piece shown under Incoming lands in a random free spot. The game ends when that piece has nowhere to fit.

How does scoring work?

You score for every block that lands and every block you clear. Clearing several lines at once multiplies the points, and clearing on back-to-back moves builds a combo that multiplies them again.

Can I undo a move?

Yes. Tap Undo under the board to take back your last move, up to three times per game. You can also undo from the game-over screen if you have undos left.

How do I turn the sound off?

Tap the speaker icon at the top right of the game. Slide Stack also stays quiet when your phone's silent switch is on.

I lost my best score.

Your best score is saved only on your device. Deleting the app, or moving to a new device without restoring a backup, resets it.
