Stack It! Sorting Puzzle vs Shade Shape

Stack It! is a satisfying color sorting puzzle game where every move matters. Tap columns to stack tiles, sort colors, and complete each column with a perfect color match. Plan your moves carefully, use the available space wisely, and find the right order to solve each level. As you progress, new challenges appear. Mystery “?” tiles hide their color until revealed, making every move more strategic. Frozen columns block your options and force you to think ahead before you can complete the puzzle. Easy to learn and relaxing to play, Stack It! blends simple controls with smart color sorting challenges.
