🧩 Rainbow Sort Stacks

<p>Bright rainbow stacks beg to be untangled tube by tube in a relaxing pour puzzle that's hard to put down. Rainbow Sort Stacks is a soothing colour-sorting puzzle where you pour balls between tubes until each tube holds a single colour. Under the surface it's quietly training forward planning, ordering and patience. Short rounds and a saved personal best make it easy to pop in for one quick attempt and find yourself still playing ten minutes later. It's built for players everywhere, with crisp controls and clean visuals that feel at home from New York to London to Sydney. undefined Beat a personal record and the built-in share buttons let you challenge a friend on WhatsApp or Telegram in one tap. There are no timers forcing you to rush unless the game itself adds one, so you can play at your own thoughtful pace. Controls are dead simple to learn but the depth keeps revealing itself the more you play. It sits comfortably alongside the other thinky games in our collection if you fancy a change of pace.</p>
