Gem Sort is the sorting puzzle that quietly eats an evening: flasks full of mixed-up gems, two empty ones, and a single rule — a gem only lands on its own colour. Untangle the mess one pour at a time.
The sort puzzle is the quiet superstar of modern casual gaming — the ball sort and water sort family has been downloaded hundreds of millions of times, and it never needed a tutorial. You see mixed colours in glass tubes, and something in your brain simply refuses to leave them like that.
Gem Sort keeps the beloved rules intact: each flask holds four gems, a gem can move only onto a matching colour or into an empty flask, and matching gems on top move together. Fill a flask with four of a kind and it locks in with a satisfying flash. Sort every colour and the level is yours.
The trap, as every sort-puzzle veteran knows, is the empty flask. Spend your free space carelessly and you will find yourself staring at a board where nothing moves. That is what the undo button is for — and unlike many clones, it is free and unlimited, because the puzzle should be about thinking, not about rationing mistakes.
Every level here is generated and then verified by a solver before you ever see it, so there are no dead deals — if you are stuck, the way out exists. Levels grow from a gentle three colours to a dense eight, and your progress saves automatically between visits.
How to play Gem Sort
One rule and two empty flasks — that is the whole game:
- Tap a flask to lift its top gem (matching gems on top travel together).
- Tap another flask to pour — gems land only on the same colour or in an empty flask.
- Fill a flask with four gems of one colour to lock it in.
- Sort every colour into its own flask to clear the level.
- Stuck? Undo is unlimited, and restart reshuffles nothing — it replays the same solvable deal.
Tips for Gem Sort
- Guard your empty flasks — they are the only working space you have, so spend them on purpose.
- Plan two pours ahead: the best move is often the one that frees a colour underneath.
- Dig out the colours buried deepest first, while you still have room to manoeuvre.
- Avoid stacking a colour on top of a single stray gem you will need to move again.
- A free undo is a thinking tool: try a line, read the result, roll it back.
Who made Gem Sort?
Gem Sort was built by crokocat game studio in 2026 — a polished take on the classic ball sort puzzle with glass flasks, faceted gems and solver-verified levels, tuned for mouse and touch.
