What kind of puzzle game this is

Screw Bolt Out is a puzzle game built around taking screws out of wooden boards. Each level presents a locked assembly, and the goal is to loosen and remove the bolts in a sequence that lets the boards come free.

The developer describes it as easy to pick up and hard to master, and aimed at players of all ages. The content rating on Google Play is Everyone.

Working out the order of removal

Each puzzle depends on logic and observation. You study how the boards are held together and work out which bolt has to come out first, since the wrong order leaves the pieces stuck.

The listing says a single wrong move can lock everything in place. Because of this, the game is about planning each removal before you make it.

Levels, unlocks and progression

The game includes more than 100 levels, which you unlock as you progress through the puzzles. Difficulty rises from simple setups to tricky mechanisms, with the listing describing the early levels as quick to start.

Progress carries from one level to the next, so the later puzzles are where the harder mechanisms appear.

Screw physics, sound and touch

The screws behave according to a realistic mechanical model and the boards react with physics when they are released. The developer presents this as a core part of the satisfaction of the game.

Sound design is built around ASMR-style effects, with textures on the wood and metal surfaces. Because the game runs offline, it can be played anywhere without a network connection.
