Hue Lab – Pour & Mix Puzzle

Hue Lab is a calm pour-and-mix puzzle. Tap a tube to lift it, tap another to pour. A colour pours only onto the same colour or into an empty tube. Gather every colour into its own tube and the level is done. • Endless chapters of ten: two tutorial levels, then generated puzzles that climb from three colours to eight. Every board is dealt into full tubes, and the generator throws away any level that obvious moves would solve, so there is always a decision to make. • Chapter rules that change the game. Mix: pour red onto blue and the run becomes purple, so some colours have to be made. Fog: colours stay hidden until you uncover them. Capped: one tube is sealed until you finish another. Burst: a finished tube pops and frees itself. The rules cycle, so no two chapters play the same. • Three stars for finishing near par. Replay any level and it returns with new colours and a fresh layout. Hints and extra tubes are yours to keep: start with a few, and when they run out a short video tops them up. A level solved with help still earns two stars. • Daily challenge: one puzzle a day, the same for everyone, with a streak to keep. • Unlimited undo, no lives, no timers. If a board cannot be finished any more, the game tells you. • Liquid, gem or block tube styles; English and Russian; light and dark themes. Plays offline. Free, supported by ads.
