Bolts Puzzle: Nuts & Screw Pin

Bolts Puzzle: Nuts & Screw Pin drops you into a workshop of tangled hardware, where every level is a fresh mental workout. The goal is simple to grasp but tricky to master: pair each loose nut with its matching screw and slide the pins free. What starts as a relaxed sorting task soon becomes a web of interlocking choices, where one careless move can lock the whole board. As you progress, the puzzles grow more layered, introducing colored bolts, hidden slots, and limited moves. You will need to plan several steps ahead, rethink your approach when a piece jams, and use the empty spaces wisely. There is no timer rushing you, so the pace stays calm even when the logic gets dense. Every cleared board delivers a quiet sense of satisfaction, making it easy to pick up for a few minutes or settle into a longer session of brain training.

What is Bolts Puzzle: Nuts & Screw Pin

A tidy logic challenge awaits, where nuts, bolts, and pins demand your full attention. Each level is a new arrangement of hardware that you must untangle step by step.

How to Play

Tap a nut to pick it up, then tap a matching screw to secure it. Once all nuts are placed and pins are free, the level clears.

Tips for Playing

  • Scan the whole board before making your first move to spot obvious matches.
  • Free up space in crowded areas by clearing easy pairs early on.
  • Use the screw slots strategically, since placing one nut can block another.
  • When stuck, undo a few moves and try a different pairing order.
  • Keep an eye on pins that are nearly exposed; they often unlock new options.
