Liquid Color Sort

Liquid Color Sort is played entirely with the left mouse button. Each level shows a set of tubes holding layers of coloured liquid, and you pour from one to another until every tube contains just one colour.

The developer describes the rules as simple and makes no claim to a twist. What changes is the material you are working with. As you progress, new colours appear and the tubes are arranged in new ways, so a method that worked on one layout may need rethinking on the next. The game also nudges you towards efficiency, suggesting you look for the most efficient way to sort the liquids rather than settling for any solution, although it does not say whether moves are counted or scored. The developer pitches it as calming brain training, and the tubes are presented in a landscape frame.

Click a tube with the left mouse button to select it. Click a second tube to pour liquid into it. Keep pouring between tubes until each one holds a single colour, which completes the level. The developer's advice is to think each move through before making it, since planning is what the puzzle asks of you.

New colours and tube arrangements arrive as you advance, so look over each fresh layout before starting rather than repeating the last solution. The developer suggests aiming for the most efficient route, which means fewer pours; it does not say this is scored, so treat it as good practice.
