Crystal Cave Sort

Crystal Cave Sort takes the sorting-puzzle idea everyone has seen with water bottles or colored balls and reskins it as a glowing underground cave. Each tunnel holds a jumbled stack of gems - ruby, sapphire, emerald, amethyst and more - and the goal is to pour them between tunnels until every one holds a single color from top to bottom.

There is no timer, so the challenge is pure sequencing: pour the wrong gem into a nearly sorted tunnel and you can box yourself into a dead end. Two hundred levels across eight cave worlds keep introducing new tunnel layouts, and choosing Easy, Medium or Hard changes how much room you get. Progress saves automatically, so an unsolved level waits right where you left it.

How to play

Tap a crystal tunnel to select the gems sitting on top, then tap another tunnel to pour them across. Gems only stack on top of a matching color or an empty tunnel, so plan a few moves ahead rather than pouring on impulse. Clear a level by sorting every gem type into its own tunnel, then move on to the next cave world. Pick Easy, Medium or Hard difficulty to change how tight the puzzle is.

Controls

Tap a crystal tunnel with your finger or mouse to select it, then tap the tunnel you want to pour into. No other controls are needed.
