Color Sort Challenge: Puzzle

Color Sort Challenge is a calm, satisfying liquid-sorting puzzle. Tap a tube to lift it, tap another to pour. The top color flows across only onto the same color or into an empty tube. Sort every color into its own tube to win.

★ 200 LEVELS
Start with two colors and plenty of room, and work up to twelve colors and as few as one spare tube. Every level is proven solvable before release.

★ THE FEWEST POURS
Each level shows a target: the smallest number of pours that solves it, proven by a solver. Match it for three stars.

★ EASY TO LEARN
A short tutorial in the first three levels shows you everything you need. No timers, no pressure.

★ HELP WHEN YOU NEED IT
• Hint shows the next pour from exactly where you are
• If a position has no way forward, the game tells you, so you can undo
• Unlimited undo and restart
• Progress is saved after every pour

★ COLOR-BLIND FRIENDLY
Every color carries its own symbol (circle, star, triangle and more), and the twelve colors were chosen to stay distinct for common types of color blindness. Turn the symbols off in Settings if you prefer.

★ MADE FOR EVERY PHONE
• Plays fully offline, no account or sign-in
• English, தமிழ் and हिन्दी
• Light and dark themes, reduce-motion option, sound and vibration switches
• Back up your progress to a file or to your own Google Drive
