Better hands earn bigger scores and higher multipliers. Easy to learn and satisfying to master, Stacks turns every card into a decision. Will you finish a flush, build a full house, or save the perfect card for another direction? BUILD YOUR BEST BOARD Draw six cards and place five. The remaining card joins your discard hand, where it can help your score too. Tap to place cards or drag them onto the grid, and use Undo when you want to rethink your last move. KEEP YOUR GUIDE BESIDE YOUR GAME On an unfolded iPhone Duo or a larger iPad window, keep the scoring guide, trophies, or game history open on the left while you play on the right.

PLAY DAILY AND CUSTOM PUZZLES Return for a new daily puzzle, start a game with a custom game number, or replay a favorite from your history. Try a different strategy and see if you can beat your previous score. MAKE IT YOURS Enjoy light and dark mode, plus a collection of card themes to match your style.
