About this game
Sounds easy — until the parts start overlapping. A bolt under a plank cannot be turned before you clear whatever lies on top of it, and the tray below has only a few free slots. One wrong order and you are out of moves.
⭐ Inside:
• Endless levels, each one harder than the last
• Three boosters: drill, magnet and level skip
• Daily rewards every time you come back
• Leaderboard: who got the furthest
• Cloud saves, so progress is never lost
• Plays on phone and desktop alike
Like nuts-and-bolts puzzles or sorting games in general? The mechanic will feel familiar, but the difficulty is real: past level ten, guesswork stops working.
How to play
✅ Tap a bolt — it unscrews and flies into the barrel of its colour.
✅ A barrel holds three bolts. Once full it drives off and the next one from the queue takes its place.
✅ If no barrel of that colour is open, the bolt goes to the tray underneath.
✅ Overflow the tray and the level is lost. Always keep a slot free.
✅ A bolt under a part cannot be unscrewed: clear what lies on top first.
🔧 Stuck? Use a booster:
• Drill — adds one more slot to the tray
• Magnet — pulls out every bolt matching the right-hand barrel
• Skip — jump over the level entirely
Boosters cost coins or come free for watching an ad. Coins are earned by finishing levels and from daily rewards.
