Royal Stack

Welcome to Royal Stack, an addictive and satisfying color sorting puzzle where every move requires strategy and planning. Challenge your brain by organizing colorful card stacks, solving increasingly difficult puzzles, and mastering hundreds of unique levels.

Each level contains a grid of card stacks filled with different colors placed in a completely random order. Below the puzzle is a special Rainbow Card Holder that always contains a rainbow card, giving you a unique way to manipulate every stack.

Tap any column in the puzzle to use the Rainbow Card. The rainbow card is placed on the top of the selected stack, pushing every existing card in that stack one position downward. As the cards shift down, the bottom card leaves the stack and moves into the Rainbow Card Holder.
