Bolt Out: a nuts and bolts puzzle in the workshop

Bolt Out is a nuts and bolts puzzle on a workshop pegboard: wooden planks are held up by colored screws, and you take the whole build apart. Each screw flies into the open toolbox of its color, but if no box for that color is open it waits in a small tray. Choose the order well, because a full tray ends the level.

Bolt Out pegboard with wooden planks held by colored screws, two toolboxes and the five-slot screw tray to the right

How to play

Tap a screw to unscrew it; it spins out and flies into the open toolbox of its color.
Fill a toolbox with three screws and it snaps shut and rolls away while the next color rolls in.
Screws with no open box go to the tray, which holds 5 screws, or 4 from level 101.
Remember that screws under a plank cannot be reached until that plank swings away or falls.
Pull every screw to clear the build; finish without helpers for three stars.

What it exercises

Like any nut and bolt game, this workshop puzzle is about sequence: the right screws, at the right time.

Planning ahead
A NEXT preview shows which toolbox color comes after the current one, and you plan which screws to free now so they have somewhere to go.
Spatial reasoning
Planks overlap in layers and swing on their last screw with real physics, so you picture what will be uncovered before you pull.
Working within limits
The tray is small, so every screw that cannot go into a box uses up space you might need later.

Tips

Before each tap, ask whether that screw has an open box. If not, it costs a tray slot.
Clear the top planks first. Screws hidden underneath are stuck until the plank above them is gone.
Each color also has its own symbol, such as a dot, square or star, so you can tell screws apart at a glance.
Every level gives 3 undos, 1 extra tray slot and 1 pair of pliers that pulls any screw, even a covered or locked one; each use costs a star.
Padlocked screws open once the screw carrying their key is out; glass planks shatter as soon as one of their screws is pulled; chained planks fall together.
Every tenth level is a hard one where every tray slot counts.

Is there a screw puzzle game with no ads?
