Color Nuts & Bolts Puzzle and the screw-by-screw color match
Color Nuts & Bolts Puzzle brings a bolt-loosening challenge to the puzzle screen, and you have to study each build before you move. Click or drag the pieces so every screw ends up with the nut of the same color, then keep clearing the structure without blocking yourself.
Match colors before the board locks up
Each arrangement asks you to think a step ahead, because one wrong move can leave a screw trapped behind another. The game leans on matching and spatial planning, so you are always checking where the next colored piece can actually fit.
Disassemble the design one fastener at a time
The main mechanic is simple: loosen the bolts in the right order and break the structure apart piece by piece. That rhythm gives each round a clear goal, and the point score rises as you finish boards cleanly.
Challenge mode reveals the picture underneath
In challenge mode, completing the puzzle uncovers a full image, so every solved board gives you a visible payoff. If you want a broader test of the same kind of thinking, Crazy Screw King and Screw Master 3D: Pin Puzzle use similar screw-removal ideas, while Prism Match 3D pushes color sorting in another direction.
The result is a clean browser puzzle that works well for short breaks, with no download and no signup. Colors stay front and center, so you are always reading the board, matching the right fastener, and finishing each design instantly in your browser.
