About this game
Unscrew, sort, and clear the board. Screw Sort is a calm nuts-and-bolts puzzle with 300 handcrafted levels — and every single one is guaranteed to have a solution.
HOW IT PLAYS
Tap a holder and the top run of matching screws lifts out. Tap another holder and they land. Fill a holder with a single colour and it locks in, finished. Clear the board to win.
That is the whole rule set. The first level teaches it in seven moves. Level 300 will not.
EVERY LEVEL IS PROVABLY SOLVABLE
Most sorting puzzles shuffle the board at random and hope. A random deal of screws can look completely normal and still be impossible — every holder jammed with mixed colours and nowhere left to move. You only find out after ten minutes of trying.
Screw Sort does not shuffle and hope. Every level was solved by the game itself before it shipped, and the length of that solution became the level's par. So the three-star target is not a guess either — it is a route that is known to exist. If you match it, you found the best line.
NO INTERNET NEEDED
All 300 levels ship inside the app. No download on first run, no server, no account, no sign-up. It works on a plane, on the Tube, and on a dead SIM.
FEATURES
- 300 levels across chapters that tighten as you go
- A fresh Daily Challenge every day, with a streak to keep
- Three stars per level, measured against a solution that is proven optimal
- Undo any move, and a hint when a board stops making sense
- An extra holder when you are genuinely stuck
- No timer and no lives — think for as long as you want
- Plays entirely offline
WHO IT IS FOR
If you like Water Sort, Ball Sort, Hoop Sort or Nuts and Bolts puzzles, this is the same itch with tighter levels and no dead ends. If you have ever restarted a sort puzzle wondering whether it was ever winnable at all — this one always was.
Free to play, with optional ads to earn hints and extra holders.
