Crystal Express: Gem Sort

All aboard the Crystal Express! Every cart is full of sparkling gems. Can you sort them all?

Crystal Express is a relaxing gem sort puzzle in a cozy crystal mine. Carts full of colorful gems wait around a little railway, and the express gem train rolls round and round the loop. Tap a cart and its front gems hop into a wagon. The train carries them to the next cart with the same gem in front and a free slot, and in they pour. Fill a cart with one gem and it fuses into a big shiny crystal!

HOW TO PLAY
• Tap a cart: its front gems hop into one wagon of the express train.
• The train drops them into the first cart with the same gem and room, or into an empty cart.
• No match yet? The gems keep riding until a cart is ready for them.
• Free wagons glow, so you always see how much room the train has left.
• Fill every cart with one gem to clear the mine.

100 LEVELS, NEW TRACKS
• 100 levels, every one checked to be solvable, from cozy warm-ups to HARD and SUPER HARD mines.
• SUPER HARD mines are named after the world's most famous diamonds. Can you crack the Koh-i-Noor?
• New track shapes keep the puzzles fresh: tunnels that hide the riders, U-tracks, island loops, L-bends and tall loops with 8 carts.
• Mystery ore, dark mines, double veins and 8 kinds of gems.

TRAIN YOUR BRAIN
• The train has only a few wagons, so the order of your taps matters.
• Each new idea comes with a short card that shows how it works.
• No timer. Out of room? Add a cart, rewind to your last good move or try again.

HANDY BOOSTERS
• Undo: take back your last tap.
• +2 Wagons: two extra wagons join the train.
• +1 Cart: a new empty cart rises from the floor.
• Lantern: light up the mine and see the gems inside every mystery ore.

YOUR MINE, EVERY DAY
• Follow the rails deeper into the mine on the level map, with a cheerful mole miner as your guide.
• Open the Daily Chest for free coins every day.
• Earn stars and coins on every level and fill the Gem Jar as you win.

MADE FOR SHORT BREAKS
• One finger to play, quick levels.
• Calm music, soft sounds and smooth, satisfying gem pours.

Tap the carts, load the train and sort every gem. All aboard the Crystal Express!
