Circuit Sort: Screw Puzzle
Unscrew bolts & nuts: Pin Jam
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Sort the screws, clear the board! New fixes make two-color screws fair, plus smoother Daily Challenge screens. Can you top today's rankings?
Unscrew nuts and bolts into the right color bins in this screw sort puzzle with a retro electronics repair twist. Plan every tap — one wrong screw can jam the whole board.
HOW IT WORKS
Match colored screws to matching bins on the circuit board. Slots fill as you go. Think ahead, clear the plate, and keep the bench running. Twist, tap, and drop screws into the right hardware until every board is fixed.
FEATURES
• 175+ handcrafted levels — easy to learn, hard to master
• Arcade mode — endless boards with random starts and rising intensity (hard-capped so it stays fair)
• Daily Challenge — one fair timed puzzle each day (no undo, no power-ups)
• Rankings — rotating competitions across levels and Arcade, so there's always something to climb
• Power tools — drill, hammer, and dust pan when you need a save
• Workbench — collect trophies, skins, and gear as you progress
• Game Center — achievements and leaderboards
• Play in your language
WHY PLAYERS STICK
Satisfying screw-sort gameplay with wood-and-metal vibes, pin-jam tension, and color-match logic. Quick sessions when you have a minute. Deep boards when you want a longer run. Perfect for puzzle fans who love nuts-and-bolts games, bolt puzzles, screw sort, and brain teasers.
Optional in-app purchases: coin bundles, coin doubler, remove ads, and a piggy bank. Ads can be removed with a one-time purchase.
TIPS
Watch the upcoming bins. Don't fill a color until you can clear it. Save tools for the jammed boards. In Arcade, intensity climbs every few clears — stay calm and keep sorting.
