Bolts and Nuts Online

Bolts and Nuts Online is a mechanical puzzle game centered on careful planning. Each puzzle asks you to remove, arrange, and manage bolts and nuts until the mechanical setup is complete. The controls are simple, but the decisions require logic because moving one piece can affect how the remaining parts are handled. Its clean puzzle structure makes the satisfaction come from finding an orderly solution rather than rushing through a board. The game is available for mouse play on desktop, tablet, or mobile, so the main challenge remains the same across devices: understand the arrangement, choose a useful removal or placement, and work methodically toward completion.

Click with the mouse to select and manipulate bolts or nuts.

Remove pieces when doing so helps clear the mechanical arrangement.

Arrange the remaining parts into a workable order.

Manage each bolt and nut carefully until the puzzle is complete.

Plan several actions ahead instead of moving parts without a clear purpose.
