Wood & Screw Puzzle is an unscrewing puzzle: wooden planks are held together by bolts, and removing them in the right order lets the stack come apart — while the wrong order jams it.
It's the same satisfaction as taking something apart properly, which is why the genre took off. Nothing is timed and the levels are self-contained.
The order. Each bolt holds specific planks in place, and removing them in the wrong sequence jams the stack rather than freeing it.
No — it's built as a relaxing puzzle, so you can take as long as you like.
Yes — tap the bolts. Nothing to install.
