Screw Jam Puzzle

Pull a bolt loose, drop it in the wrong box, and watch your neat little board turn into a jam. That's the loop in Screw Jam Puzzle: unscrew each board, drop the pins one by one, and match colors until every screw box is filled with the right shade.

Five minutes in and you're already several boards deep, because there's no timer breathing down your neck here. You play at your own pace, which means you can chase one more clean solve on your lunch break or settle in for a longer session without ever feeling rushed.

Hundreds of levels means the sorting never quite repeats itself, and when a board gets genuinely tricky, boosters are there to bail you out. It's the kind of game that rewards the part of your brain that can't leave a mismatched drawer alone - if that's you, this sits nicely alongside other Puzzle games built for the same itch.

Works on Android, iOS, and desktop, right in the browser, free, no download. Fans of Collecting Games and Brain Training Games will feel right at home sorting nuts and bolts one board at a time.

Clear every screw box by filling it with screws of a single matching color - that's the win condition on each board.

Unscrew the board and the pins drop out one by one. Match colors as they come and slot them into the right box. There's no time limit, so take as long as you need to plan each move.

If a board has you stuck, use a booster to get past the tricky spot. With unlimited levels to work through, it's worth experimenting with different sorting orders instead of grabbing the first color you see.
