Step onto the factory floor and put your precision to the test! Screw Master is a casual game in the factory simulation genre. Based on real-life factory screwing scenarios, it creates an engaging and challenging fingertip operation experience that combines fun and difficulty. The game adopts a concise and lively cartoon art style, paired with realistic screwdriver rotation sound effects and vibration feedback, making players feel as if they are standing at a real workbench. From simple wooden boxes in the early stages to complex mechanical structures later on, the shapes of the items to be assembled constantly change, while the number, distribution density, and types of screws gradually increase in difficulty. From the rhythmic "clink" of a perfect fit to the pressure of a ticking clock, Screw Master offers a perfect blend of ASMR relaxation and brain-teasing puzzles.

Your mission is simple but demanding: tighten or remove screws with surgical precision under various constraints. You must strategize your workflow, select the right specialized tools, and utilize power-ups to achieve "Flawless Clear" ratings. Efficiently complete tasks to climb the ranks, unlock secret levels, and earn the title of Legendary Technician.

How to complete the screw-tightening task more quickly during operation?

Practice your hand speed in Free Mode, continuously accumulate experience, and you can also speed up the screw-tightening process by purchasing and upgrading props.

What other modes are there besides Free Mode?

There is also a Challenge Mode, where you can improve your combat power by participating in challenges. Before a challenge starts, it is recommended that you first upgrade and purchase items to enhance your existing tools—only then can you achieve your desired goals in the challenge.
