Hueflask: Water Sort Puzzle

Hueflask is a water sort puzzle, a liquid sort game without the clutter. A row of bottles, each with room for four layers of color.

Tap a bottle and its top run of one color lifts. Tap a second and it pours - into empty glass, or onto the same color, and only as much as fits. The board is done when every color stands alone in its own bottle.

The climb is the colors, not the clutter. Three colors 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 - 1800 boards, from three colors 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:
• Gold, silver or bronze on every board, by how close you came to par.
• Hints come back on their own over time, or right away with a video.
• Color-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.
