About this game
Unscrew the bolts and let the plates fall. Every bolt drops into the parts bin: three of one colour fill a box and free a slot. Four slots, six colours, sixty drafts — clear every plate before the bin jams.
How to Play
Tap or click a bolt to unscrew it; rusty bolts need two turns. Tab or arrows select, Space unscrews, Z undoes, R restarts, P or Esc pauses, M mutes.
Tips & Tricks
- A bolt can only come out if no plate above it covers it — clear the top plates first.
- Watch the bin: three bolts of one colour fill a box and free that slot.
- A rusty bolt takes two taps; the first only loosens it.
- A full bin with no matching colour is a jam. Undo (Z) costs only a second.
- Finish one colour at a time; later drafts stack more plates and fewer colours.
