CleanSort: Honest Sorting Game

No ads, no pop-ups, no "watch a video to continue." No fake currency. No timers pressuring you. No puzzle secretly rigged to be unsolvable so you'll watch a rescue ad.

CleanSort is ball sort the way it should have been all along — a calm, honest color-sorting puzzle you can play on a plane, hand to a kid, or share with a friend, without anyone trying to sell you something or interrupt your train of thought.

WHAT MAKES IT CLEAN
- No ads, ever. Not between levels, not on restart, not mid-puzzle — and not a banner parked at the bottom of the screen. None.
- No in-app purchases, no subscriptions, no "premium." The whole app is yours.
- Every new deal is guaranteed solvable — checked by a built-in solver before you ever see it. You'll never be handed an impossible puzzle.
- Works fully offline. No account, no sign-in, no tracking.

BUILT FOR PEOPLE WHO ACTUALLY LIKE THE GAME
- Unlimited undo — take back as many moves as you want, no penalty, no watching anything.
- Optional hints when you're stuck — and a hint is the real answer: the first move of a shortest solution, not a guess. (Games you needed a hint on don't count as clean wins. Fair's fair.)
- The grudge list: needed a hint? That deal is remembered. Rematch it any time — beat it without help, and the grudge is redeemed.
- Bookmarks: mark a position you're unsure about, experiment freely, and jump straight back.
- Smart pours: a run of same-colored balls moves together in one move, the way the puzzle really works.

SHARE PUZZLES WITH FRIENDS AND FAMILY
Every deal has a short shareable code. Send a fiendish one to a friend, or compare how you each cracked the same puzzle.

WHY IT EXISTS
I got tired of ball sort apps stuffed with ads and dark patterns, and I wanted my own kids to have a clean one. So I made it, and I'm sharing it. That's the whole story.
