Nuts and Bolts is a 3D puzzle game in Playtua. Unscrew bolts and remove wooden planks to solve tricky mechanical puzzles! Tap a bolt to unscrew it from a plank. Tap an empty hole to screw the bolt in. Remove all planks by unscrewing their bolts.
Nuts and Bolts is a sequencing puzzle in which removing a fastener can change the whole arrangement. Unscrew a bolt, move it into an available hole and work towards releasing every plank. Some bolts are blocked by other planks, so the visible fastener is not always one you can use immediately. The 3D construction makes the layers easier to inspect, giving you a reason to study which parts depend on the pieces above them. Look at both the bolt you want to remove and the empty hole you plan to use. Freeing one part is less useful if the moved bolt blocks the next necessary action. Start with accessible fasteners and watch how each removed plank changes what is available underneath. If a sequence becomes cramped, consider whether a different first move would preserve more working space. The central question is not simply which bolt can move now, but which move helps release the next part of the structure.
