About the game
Stack Attack is a colorful stack-sorting puzzle where every move deserves a little thought. Tap a stack to pick up its top piece, then place it in an empty stack or on a matching piece. Sort every type into its own full stack to complete the puzzle. Empty stacks give you room to plan, while Locked pieces stay put and Frozen pieces only thaw after you finish your first stack. Choose a fresh Free Play puzzle or tackle the Daily Puzzle, with difficulty levels from Beginner to Expert. It's easy to understand, but tricky to untangle.
