Coin Tray: Sort Puzzle

20 solver-verified levels plus a build-your-own challenge maker with exact scoring, QR links and offline codes. No ads, purchases, account or tracking.

Coins land in the tray in the wrong order. Sort them by colour — and the moment ten of a kind stack up together, they wrap themselves into a paper roll and drop into your vault.

That rolling payoff is the heart of Coin Tray.

HOW IT PLAYS • Tap a stack to lift the run of matching coins off the top • Tap another peg to drop them — empty pegs take anything, the rest take their own colour • Ten in a row wraps into a roll and leaves the board • No timers, no lives, no energy. Think as long as you like.

THE COINS FIGHT BACK • Counterfeits never match anything. Swipe to flick them off the table. • Rusted coins are stuck until you dig them out, then polish up as good as new • From level 10 a chute keeps feeding fresh coins onto the board while you work

BUILD YOUR OWN CHALLENGES • Arrange two to four colours across three to eight trays, with optional rust and counterfeits • Coin Tray proves the exact shortest solution on your device before a challenge can be shared • Send a self-contained HTTPS link or QR code, or use the offline code with no connection at all • Keep created and received puzzles, local names and best scores in your on-device library

FAIR BY CONSTRUCTION • Every campaign level is solver-verified before it ships — a complete solution always exists • Campaign stars compare your run with a verified solver benchmark • Custom challenge stars use the exact on-device proof • Three undos a level, and restart as often as you like

MADE WITH CARE • Coins are minted, layered and lit, and travel on a real arc as they cross the tray • Every sort, wrap and flick has its own sound and its own weight in your hand • Colour is never the only signal — each coin carries its own mark and finish, and every peg reports its contents to VoiceOver

NO STRINGS • Free, with no ads, no in-app purchases and no subscriptions • No account, sign-up, analytics, attribution or tracking • Gameplay, creation, exact verification and offline codes work without a connection • Sharing happens only when you choose it through the standard iOS share sheet; Coin Tray does not upload your puzzle
