About this game
You get a handful of flasks with mixed layers. Pour liquid from one into another until every flask holds a single colour. You may only pour onto a matching colour or into an empty flask — that one simple rule carries the whole game.
It starts with three colours and works its way up to twelve. There is a second kind of level too: tight ones, with fewer colours but almost no free space, where every move has to be planned ahead.
The core promise: there are no dead ends. Every level is checked by a solver before it reaches you, so an unsolvable layout will never appear. If you get tangled up, undo is free and unlimited, and a hint will show you the right move.
For anyone who has trouble telling colours apart, symbols on the layers can be switched on in the settings.
One-handed, saves by itself, and there is no rush.
How to play
THE RULES
Tap the flask you want to pour from, then tap the one you are pouring into. The whole top layer moves at once.
You may only pour onto a layer of the same colour, or into an empty flask. A flask filled to the brim cannot take any more.
THE GOAL
Get every flask down to a single colour. Finished flasks glow green — best to leave those alone.
IF YOU GET STUCK
Undo is free and unlimited, so experiment freely. A hint highlights the flask to pour from and the one to pour into: one free hint per level. The flask button adds one more empty slot, which often breaks a deadlock. Restart puts the level back to its starting position.
ON DIFFICULTY
The first levels teach the mechanic without words. After that the colour count grows, and from level twenty-five onward you will meet tight layouts with only one free flask, where moves need planning ahead.
