Nuts and Bolts: Screwing Puzzle

Nuts and Bolts: Screwing Puzzle is a satisfying logic game about taking things apart in the smartest order possible. Each level drops you into a messy construction of iron sheets, plates, nuts, and bolts held together by screws. Your goal is simple to understand but tricky to master: remove every screw so the whole structure can fall apart and clear the board.

What makes the challenge interesting is that you can’t just unscrew everything randomly. Removed screws must be placed into a limited set of empty slots, so every move affects your future options. One wrong decision can block an important screw, trap a plate in place, or leave you with no storage space for the next removal.

How to play

The controls are straightforward, which keeps your focus on planning:

• Click or tap a screw to unscrew it.
• Move the removed screw into an available open slot.
• Keep removing screws until the connected parts are released and the structure fully disassembles.

Because pieces overlap, the order matters. Some screws can’t be accessed until another plate shifts. Others are “support” screws that hold multiple layers together. Learning to read the structure is the real skill.

What makes the puzzles work

These levels are built around a few consistent mechanics that create lots of variety:

• Limited storage slots: You can’t hold every removed screw at once, so you must manage space like an inventory puzzle.
• Layered metal sheets and plates: Parts can cover other screws, forcing you to free layers step by step.
• Dependency chains: One screw might be the “key” that releases several pieces, but only if the surrounding parts are prepared first.
• Hints and tools: If you get stuck, the game offers help so you can learn the intended logic instead of quitting a level.

The result is a calm but challenging experience that feels like mechanical problem-solving: observe, predict what will move, then commit to a sequence.

Tips to solve levels faster

• Count your open slots before you start. If you’re nearly full, avoid removing “extra” screws that don’t immediately free a section.
• Look for blocking layers. If a plate covers other screws, prioritize the screws that unlock that plate first.
• Save one slot for emergencies. Keeping at least one empty spot helps you avoid dead ends when an unexpected screw becomes necessary.
• Remove stabilizers last when possible. Screws that hold multiple parts together can cause a big shift; make sure you’re ready for the change.
• Use hints as a learning tool. If you’re stuck, a hint can reveal the next logical step and teach you what you missed in the structure.
