Glug: Color Puzzle

Glug is a liquid-sorting puzzle. A rack of glass vials holds layers of coloured liquid that have got thoroughly mixed up. Tap a vial, tap another, and the top colour pours across, as much as will fit. Keep pouring until every vial holds a single colour.

It starts gently, with three colours and a couple of empty vials, and builds to sixteen colours on a full rack. After that it doesn’t get harder, just different: the puzzles never run out, and every one is checked to be solvable before it reaches you.

Finish a level close to the best solution and you get three stars. Undo is free, hints are free, and Glug, a small and very cheerful water drop, points at the next pour when you ask and celebrates when you’re done.

• Endless levels, all checked to be solvable
• Free hints, undo and restart, as often as you like
• Colourblind-friendly colours, with optional symbols
• Plays offline
• No ads, no tracking, no accounts. One optional purchase removes the “enjoying Glug?” popups and changes nothing else.

Glug is coming to Android first, with iOS to follow. More news once the mittens are dry.
