The premise of Screw Rescue Squad is oddly soothing: a heap of colored wooden planks, all pinned down layer by layer with screws, and a tray waiting below. Your job is to read the stack — spotting which planks are trapping others — and back the screws out in exactly the right order to take the whole thing apart.

It scratches the color-sorting itch of the screw-and-nut puzzle format. Three screws of one color land in the tray and clear on their own, but let that tray fill up without a match and it is game over, so there is real tension under the calm. Screws hidden beneath other planks stay locked until you free them, which turns each board into a little sequencing problem, with hints and undo to bail you out when you paint yourself into a corner.

The goal — take apart every plank and free your trapped friends — carries you into steadily trickier layouts. It plays free in the browser, with a tap on mobile or a mouse click on desktop, and it is an easy recommendation for anyone who likes an orderly, low-stakes thinky game.
