Nuts & Bolts Puzzle

Tap, twist and watch the wood fall! Nuts & Bolts Puzzle is a relaxing screw sorting game where every board is a little wooden machine waiting to be taken apart.

HOW TO PLAY
Tap any screw that is not covered by another plank. It spins out and flies into the box of the same color. Each box holds 3 screws: once it is full, the lid snaps shut, the box flies away and the next one slides in. Screws whose color has no open box wait in the holding tray. Remove every screw to clear the level, but plan carefully: if the tray fills up, the level is lost.

REAL WOODEN PHYSICS
When a plank is left hanging on its last screw, it creaks and swings down around it like a real pendulum. Take that screw too and the whole plank tumbles off the screen. A swinging plank can cover or uncover other screws, so every move changes the puzzle.
