Bolt Out is a screw puzzle: colourful plates are screwed to a board in layers, and you have only a few free holes. Move screws one at a time until each plate has none left and drops away — clear the board in as few moves as you can.
A screw pins every plate that has a hole where it sits. Take out all of a plate's screws and it falls.
You can only put a screw into a hole if every plate lying over that hole has a hole there too — and then the screw pins those plates as well, so think before you park it.
Every level is checked by a solver, and the fewest moves it needs is shown: match it for three stars.
Undo and restart are free, and the bulb shows a good next move from wherever you are.
Boards grow from two plates to nine, with bars across, diagonals and L-shaped plates stacked on top of each other.
Bolt Out is a screw puzzle of the nuts-and-bolts kind that has filled the mobile charts for the last few years — Wood Nuts & Bolts Puzzle, Screw Puzzle: Nuts & Bolts and many more. The idea is the same in all of them: plates are screwed to a board in layers, there are only a few free holes, and you move screws one at a time until every plate has nothing holding it and drops away. Bolt Out keeps it clean and fair: no timer, no tool shop, every board checked by a solver and a best-move count to beat.
The thinking starts at the top. The plate lying on top is usually the one blocking holes, so free it first. Free holes are precious — don't fill one with a screw you'll have to move again — and remember that a screw can pin two plates at once, so moving the right one can drop both. The glowing holes are exactly the ones you can use. Bolt Out is free on crokocat and plays in the browser on desktop, phone and tablet with no download; undo, restart and the hint bulb are always free.
How to play Bolt Out
Drop every plate:
- Tap a screw to lift it.
- Tap a glowing hole to put it there.
- A plate with no screws left falls.
- Avoid parking screws where they pin a plate you still need to free.
- Clear the board in as few moves as you can.
