About

Stack 21 is a simple number-stacking puzzle game that’s easy to learn and surprisingly hard to put down.

Choose numbered tiles and build your stack toward 21. Hit exactly 21 to clear the stack and build your streak. Go over 21 and you take a strike. Three strikes ends the game.

Think ahead, watch the total, and see how high you can score.

Your game progress and high score stay on your device.
