How do you play Screw Jam?

Tap a colored screw to unscrew it. If it matches the active toolbox, it drops in. Otherwise, it sits in one of the 5 staging holes. When all holding screws are removed from a plank, the plank drops off the board!

What causes Game Over in Screw Jam?

You get a Jam when all 5 staging holes become filled with screws that do not match the current active toolbox, leaving no available space to unscrew further.

Does Screw Jam work offline?

Yes! Screw Jam is an offline-ready Progressive Web App (PWA). You can add it to your mobile Home Screen and play anytime without internet connection.

How to Play Screw Jam

Inspect the Layers: Examine the overlapping wooden and acrylic planks to see which screws pin multiple layers together.
Check Active Toolboxes: Look at the active colored toolbox at the top (e.g. Yellow, Blue, Red). Tapping a matching screw sends it directly into the box.
Use Staging Holes Wisely: Unscrewing a non-matching screw places it in one of the 5 temporary staging holes. If all 5 holes fill up without matching the box, you jam!
Drop Planks: When all screws holding a plank are removed, the plank drops off the board, revealing lower screws and clearing the board!
