About Bolt Bench
Bolt Bench is a relaxing screw puzzle on a toy workbench. Coloured screws pin layered plates to the bench, and you can only unscrew a bolt when no plate above it is in the way. Pack each screw into the toolbox of its colour, park the rest in a small spare tray, and watch the plates swing and drop until the bench is clear.
Unscrew colourful bolts from stacked toy plates and pack them into matching toolboxes — every emptied plate swings and drops off the workbench.

How to play Bolt Bench
Mouse
Click an uncovered screw to unscrew it. It flies into the toolbox of the same colour, or into the spare tray if that colour's box is not out yet.
Touch
Tap an uncovered screw to unscrew it. Screws under a plate are dimmed and must be uncovered first.
Keyboard
H shows a hint, Space or Enter performs the suggested move, and R restarts the level.
💡 Tips & tricks
- Look at the toolboxes first: screws that match an open box never use up a spare slot.
- Unscrew from the top layers early — every plate that drops can uncover several screws below it.
- The spare tray holds five screws; it glows gold and then coral as it fills, so finish a toolbox before parking more.
- Each screw colour also has its own drive shape (cross, star, heart and more), so you can tell them apart without relying on colour.

Bolt Bench FAQ
Can every level be cleared?
Yes. Each level is built together with a working unscrewing order, and a checker replays that order with the real rules to make sure the bench can be cleared without overflowing the spare tray.
What happens when the spare tray is full?
If the tray is full and no uncovered screw fits an open toolbox, the level ends. You can try again, or watch an optional ad to add one extra spare slot and keep going.
How are stars awarded?
Three stars if you clear the bench without a continue and keep the spare tray at least as tidy as the reference solution, two stars for any other clear, and one star if you used a continue.
