Liquid Sort

Pour colored water between tubes until each one holds a single shade—sounds simple until you're three moves deep and trapped by your own last splash.

Liquid Sort takes that classic water-sorting puzzle and strips it down to pure, meditative frustration. You get a handful of glass tubes, some filled with stacked layers of different colored liquids, others empty. Tap one tube to pick it up, tap another to pour the top color over. But the catch: you can only pour if the receiving tube has space and its top layer matches the color you're moving. That rule turns every level into a tiny logic knot. What hooked me was the moment you realize you've painted yourself into a corner. You pour a red into what looks like a safe spot, then stare at a green trapped under two mismatched layers with no empty tube left. There's an undo button, mercifully, but even undoing doesn't feel like cheating because the puzzle resets with your brain still holding the failed path. The physics are satisfying—liquid sloshes and settles with a soft glug, colors stay crisp, and the glass edges catch the light just enough to make each successful sort feel earned. The difficulty ramps gently. Early levels are almost autopilot, then suddenly you're planning four moves ahead, mentally rearranging tubes like a chess player. No timer, no score, no lives. Just you, the colors, and the slow dawning horror that maybe this one isn't solvable. Spoiler: it is, but your first instinct will lie to you. That's the whole point. If you enjoy puzzles that punish impulsive taps, Liquid Sort will eat an hour before you notice.
