Each puzzle features interconnected bolts, nuts, and metal plates. Your task is to remove all the nuts by carefully selecting bolts to unscrew in the right sequence. Overlapping hardware and blocked paths force you to think ahead—one wrong move could prevent further progress.
Puzzles begin with simple setups, but as you advance, bolts may hold several pieces together and layers become more complex. You’ll need to analyze which bolts affect others, plan several moves ahead, and adapt as new mechanics are introduced. Calming graphics and a relaxing soundtrack keep the experience enjoyable even as difficulty rises.
Nuts & Bolts Puzzle offers dozens of carefully crafted stages, each with unique solutions and clever layouts. Players can revisit previous levels to test alternative strategies or use hints if stuck. The game adjusts to both quick thinkers and methodical players, making it suitable for a wide audience.

Your goal is to clear each level by removing all nuts. To do this, you must unscrew bolts in the correct order so that every nut can drop freely. Use the mouse to left click bolts and remove them. On touchscreen, tap bolts to interact. Only bolts that aren’t blocked can be removed. Start with simple levels to get used to the mechanics. As you progress, layouts become trickier, requiring you to think several moves ahead. Bolts may support multiple items or overlap with others. Some levels introduce overlapping hardware and blocked paths. Experiment with possible moves and use hints if you get stuck.
