Introduction
Screw is a layered sorting puzzle built around boards, bolts, and limited space. Remove only the exposed screws, route matching colors into active trays, and keep the spare rack under control until every board is cleared.
How to Play
- Tap an exposed screw to remove it from its board.
- Matching screws fly directly into the same-color tray.
- Screws without an active tray move into the spare rack.
- Fill a tray with three screws to clear it and reveal the next tray color.
- Empty every tray to win. Filling all spare rack slots ends the run.
Controls
- Mouse or touch: select an exposed screw.
- Restart: build a fresh puzzle with a new layout.
- Reward: optionally watch an ad to unlock one extra spare-rack slot when space gets tight.
FAQ
Why are some screws dimmed?
Dimmed screws are covered by a higher board. Remove nearby exposed screws and boards to unlock them.
What should I do with the spare rack?
Use it sparingly. It is a temporary holding area, not a second scoring tray.
Is every puzzle solvable?
The level generator balances colors in groups of three, but the board order still creates meaningful pressure. Plan around active tray colors before taking random exposed screws.
