SortFlow

SortFlow is a satisfying water sort puzzle that will keep your brain sharp. Pour liquids between tubes to sort each color into its own tube — sounds simple, but you'll need real strategy to solve the hardest puzzles.

HOW TO PLAY

Tap a tube to select it, then tap another tube to pour. A pour is valid only if the color on top matches the destination and there's enough room to receive it. Think ahead: one careless move can lock up the board. Every puzzle has a clean solution — your job is to find it.

Made a mistake? Undo at any time, no penalty. Stuck on the next move? Use a hint for a guided nudge in the right direction. A game timer runs so you can track your personal bests.

FIVE DIFFICULTY TIERS

SortFlow grows with you. Start with Relaxed puzzles and work your way up through Easy, Medium, Hard, and Master. Each tier unlocks based on your performance, so you earn access to more complex challenges as your skills sharpen. Harder tiers add more tubes and more colors, turning each puzzle into a genuine brain workout.
