About Bolts - Unscrew It
There are fewer empty holes on the board than there are screws. You unscrew a screw from a wooden plank and move it into an empty hole. When a plank runs out of screws, it falls away, and its holes become free too. In Screwloose Cats: Tail Rescue, screws don't go into holes — they go into a tray, where you need to sort them by color.
So here, order is everything. One mistake can block the screw you need or leave a plank locked on the board. You clear a level when no planks are left on the board. After that, new plank shapes, obstacles, and trickier setups appear. If you get stuck, boosters can help.
