Wood Bolts Nuts Screw Pin Puzzle

Wood Bolts Nuts Screw Pin Puzzle is a digital puzzle simulation game released for mobile platforms. The game presents a series of mechanical assemblies composed of wooden planks, metal bolts, nuts, screws, and pins. Each level contains a static arrangement of these components, which are interlocked or obstructed by one another. The objective is to disassemble the structure by removing the correct fasteners in a specific sequence. The game employs a physics engine that simulates gravity and collision, causing components to fall or shift when supporting elements are removed. The visual design uses a minimalist, isometric perspective with a muted color palette, emphasizing the textures of wood and metal. The game does not include a narrative or character progression; it is a pure logic and spatial reasoning exercise. Levels increase in complexity, introducing more components and interdependent locking mechanisms. The game is categorized under the puzzle genre, specifically within the subgenre of mechanical or assembly puzzles.

Gameplay and controls are based on direct touch interaction. The player views the assembly from a fixed isometric angle. To interact, the player taps on a specific bolt, nut, screw, or pin. A tap selects the component, which then highlights. A second tap on the same component initiates its removal. The removal animation shows the fastener sliding out or unscrewing, depending on its type. Bolts and screws are removed linearly, while nuts spin off their threads. Pins are pulled straight out. The player cannot remove a component if it is blocked by another piece or if its removal would violate the structural integrity of the assembly in a way that the game’s physics engine does not allow. The game provides no hints or undo function. The only control is the tap-to-select and tap-to-remove action. The player must deduce the correct order of removal by observing which fasteners are accessible and which are holding critical load-bearing beams. A level is completed when all components have been removed and the structure has fully collapsed or separated. The game tracks the number of moves taken per level, but does not impose a time limit.
