About Crystal Cave Sort

If you have five minutes and want Fast but Smart that starts immediately, Crystal Cave Sort is the right pick.

It plays as colouring.

It ships with 200 levels, so there is always another one to unlock.

You also get characters to unlock.

No registration, no install, no ad blocking the game.

This page gives it a full frame, so the game gets the whole screen and the controls stay accurate on a phone.

Performance is kept light so older devices do not stutter, and all progress is stored locally in your browser.

Open, play, close — that is the whole flow.
