How do you play Screw Jam?

Tap bolts to unscrew them. When all bolts are removed from a plate, it falls. Clear all plates from the board to win.

What are the colored bolts for?

Each color matches a hole at the bottom. Bolts travel to their matching colored hole when unscrewed.

Some bolts may become blocked by plates above them, making the puzzle unsolvable if you remove them in the wrong order.

There are 40 levels across 5 difficulty tiers: Tutorial, Easy, Medium, Hard, and Expert.

Your progress is automatically saved in your browser using localStorage.
