Water Sort Master

Most liquid sorting games have one way to play. Water Sort Master lists six: Classic, Time Trial, Limited Moves, Sequence, Mystery and Fusion. The developer does not describe how Sequence, Mystery or Fusion change the rules, so expect to find that out by trying them.

The core task is the same throughout. Coloured liquid sits in flasks, and you shift it about until each flask contains a single colour. The rule is strict: liquid can land on the same colour or go into an empty flask, and nowhere else. The game claims more than 1000 levels. Two power-ups are named, Undo and Extra Flasks, and there are themes and bottle styles that open up as you play. It runs on desktop and on mobile, and the developer mentions sound effects and animations without going into detail.

Choose a mode from the six on offer. In a level, tap or click a flask to lift its top layer of liquid, then tap or click a second flask to pour. The liquid will only go onto a matching colour or into an empty flask. Finish with one colour per flask to clear the level and move on.

An empty flask is the only place that accepts any colour, so think twice before filling one. If a pour turns out badly, Undo takes it back, and Extra Flasks should give you more room to work with. In a mode called Limited Moves, assume your pours are rationed and plan them before starting.

A liquid sorting puzzle with six modes and over 1000 levels. Its flasks are shown in a landscape frame. According to the developer it works on mobile and desktop, using a mouse or touch.

Color Sort Party has its own extra tube booster and lets you restyle its tubes in up to 18 ways. Water Sort Legend is smaller, with over 150 levels, and scores your moves with an IQ estimator.
