Liquid Sorting

Liquid Sorting opens with a small idea from the real world. Solids are easy to sort because the pieces can be separated, while liquids normally blend together. The premise here is a liquid that refuses to mix, so it can be sorted after all.

Each level starts with long glass flasks filled with colour in separate layers. You move some of the liquid from the top layer of one flask into another, and keep doing so until every flask contains a single colour. Because the layers never blend, each transfer stays clean, and the only question is where to put things. The developer says the levels get harder as you go but does not say how many there are, and lists no boosters or timer. It is played with a mouse or by touch, in a landscape frame.

Use the mouse, or touch the screen, to move liquid. Take the top layer from one flask and transfer it into another. The colours stay separate rather than mixing, so each layer remains distinct. Carry on until each flask holds one colour, and the level is complete. Later levels are harder than early ones.

Only the top layer of a flask can be moved, so the colours lower down have to wait until everything above them has gone somewhere else. Look at what sits underneath before deciding where the top layer should go. The developer gives no rule beyond this, so experiment early.

A layered liquid sorting puzzle with long glass flasks. The flasks sit in a landscape frame. The developer states mouse or touch input. Levels grow harder; no total, timer or booster is listed.

Water Sort Master also uses flasks and adds six modes, including Time Trial and Mystery. Fun Water Sorting keeps a similar tube setup and gives you a hint and an undo for awkward positions.
