Water Sort Puzzle Master

Water Sort Puzzle Master builds its difficulty in a straightforward way: every new level puts more tubes and more colours on the screen, so the number of things to keep track of keeps growing as you go.

The task in each level does not change. Coloured liquid is spread across the tubes, and you pour between them until every colour sits in its proper tube. Pouring is done with taps. The developer does not spell out which pours are allowed, so the first levels are the place to learn how the tubes behave. Hundreds of levels are promised. The developer leans on the liquid physics and the animations as selling points, and pitches the whole thing as relaxing while still being a test of strategy. The game fills a wide landscape frame.

Use taps to pour liquid from one tube into another. Keep moving colours around until each tube holds a single colour, which completes the level. Every stage adds tubes and colours, so take a moment to look over the board before the first pour. The developer's own instruction is to plan your moves with care.

Count the tubes and colours before you start, since both numbers go up each level and a plan that worked last time may not fit the new board. If the opening pours you choose leave no free space, start again in your head before touching anything.

A liquid sorting puzzle in which each level adds tubes and colours. Tubes are shown in a wide landscape frame, and pouring is done by tapping. The developer lists hundreds of levels but names no modes, timers or boosters.

Liquid Color Sort follows a similar path, bringing in new colours and tube arrangements as you advance. Crystal Cave Sort spreads 200 levels over eight cave worlds and sorts gemstones in place of liquid.
