Hueflask is a liquid sort puzzle. A row of bottles, each with room for four layers of colour.
Tap a bottle and its top run of one colour lifts. Tap a second and it pours - into empty glass, or onto the same colour, and only as much as fits. The board is done when every colour stands alone in its own bottle.
The climb is the colours, not the clutter. Three colours are read at a glance; eight have to be planned. Two spare bottles the whole way through: a third makes any board gentle, one turns it into a lock. Every board is checked by our own solver before you see it, so it can always be finished.
• DAILY - the same board for everyone, once a day. Beat the clock, keep your streak, share your result without spoiling it.
• LEVELS - 700 boards, from three colours up to eight.
• ENDLESS - a fresh board whenever you want one. Its code sits on the board: send it to a friend and you both play the identical table.
Made to respect your time:
• No lives, no forced timers, no forced videos.
• Gold, silver or bronze on every board, by how close you came to par.
• Three hints on every board.
• Colour-blind shapes, high contrast and a choice of palettes.
• Dark mode. Works offline. Tiny download.
• No sign-up and no accounts: progress stays on your device.
Undo any pour. Nothing is ever lost to a mis-tap.
Liquid sort: pour the layers until every colour stands alone. No timers.
