About the game

Screw Jam is a puzzle about taking wooden boards apart one bolt at a time. Colored screws, pins and nuts pile up on each level, and you sort them by color to open a path forward.

Some boards stack several layers, so the order of removal matters. Later levels add rotating platforms and sliding pins that shift the puzzle while you work. You can unlock special screw tools to handle the tougher boards faster. Once the levels are cleared, an endless puzzle mode keeps going, and daily challenges hand out special rewards.

How to play

Unscrew bolts, pins and nuts and match them by color to clear the board.
On layered puzzles, remove the pieces in the right sequence to reach what is underneath.
Watch the rotating platforms and sliding pins on obstacle levels, since they change the layout as you go.
Unlock screw tools to speed up the harder puzzles, then try endless mode or the daily challenge.
