Hoop Stack: Color Sort Puzzle

Hoop Stack is a relaxing 3D color sort puzzle. Tap a pole to lift the top ring, tap another pole to drop it, and stack every color on its own pole. It's easy to learn, and each new level asks for a little more planning.

If you enjoy water sort, ball sort or nut sort games, this hoop sort puzzle will feel right at home. Instead of pouring liquid, you sort bright 3D rings with smooth animations and satisfying sounds.

A CALM BRAIN GAME
Sorting rings is a simple way to unwind after a long day, and every level is also a small logic puzzle. Think a few moves ahead, free up an empty pole at the right moment, and watch the colors fall into place.

Early levels are gentle and perfect for learning. Later levels add more colors, more rings per pole and special rings that change how you plan. If you can't see a way forward, the game tells you when no moves are left so you can undo or try again.

MORE THAN A SORTING GAME
Hoop Stack mixes the calm of a color sort game with the logic of a stacking puzzle. Every hoop sort level is checked to make sure it can be solved, so there is always a way to win.

GREAT FOR EVERY BREAK
Play one quick level on the bus or settle in for a long sorting session. Your progress is saved on your device, so you can pick up right where you left off.

Hoop Stack is free to play and supported by ads. Optional in-app purchases are available.
