Two screw games sit side by side in this catalog, and they're easy to confuse until you play them. Bolt Buddies (the other one) is about who falls. Screw Spark is a sorter: tap a screw to pull it from the board, then seat the bolt in a slot of the matching color — clear every screw, correctly filed, to finish the level.

The constraint that makes it a puzzle rather than housekeeping is space. Slots are limited, so where you park each bolt decides which moves remain possible; the order of removal matters less dramatically than next door — nobody plummets — but a careless sequence still jams the board, and getting stuck is the lose state the rules keep warning about.

Boards escalate from open, simple layouts to what the listing calls screw jam boards — crowded, interlocked arrangements that reward planning several bolts ahead. Presentation stays legible throughout: bright colors, clear screw shapes and responsive feedback on every tap, all pitched at a calm register for short breaks and focused sessions.

Scale check: 10K+ downloads, but early players are happy — a 4.8 rating. The listing gives no level total, so treat the runway as unknown; what it promises concretely is the loop itself. If you want your unscrewing with consequences, the stick figures are next door. If you want it with filing, this is the one.
