Screw Puzzle "is a single player puzzle game based on physical rules, where players need to remove bolts to dismantle the wooden structure. This game login Kuioo The platform runs for free without the need for download or installation, with hundreds of levels designed with progressive difficulty. The core challenge is to master the interaction rules between gravity and structure.

Game controls:

Click on the bolt on the wooden board with the mouse to remove it. Removing a bolt may trigger displacement or falling of the wooden board, and the chain reaction after removal needs to be anticipated. When the operation causes the structure to freeze, you can click the reset button to restart the current level.

The player faces a three-dimensional device consisting of multiple layers of wooden boards and bolts, with the goal of clearing all the boards. The core rules of the game follow two physics principles: 1 The upper wooden board presses the lower bolts, and removing the lower bolts incorrectly will permanently lock the structure; 2. A single operation may trigger a chain reaction, for example, removing key bolts can cause multiple wooden boards to fall off consecutively. The level design is divided into three stages of evolution: the initial level establishes basic cognition (such as prioritizing the removal of top-level bolts), the mid-term introduces dynamic components (removing specific bolts to rotate the wooden board and expose hidden parts), and the later high difficulty levels require precise coordination of multi-point operations. Single step errors can cause system crashes. The game enhances the experience through dual feedback: visually highlighting operable bolts and hazardous areas, and providing realistic sound effects of wood friction and metal landing through auditory feedback. The newly added challenge levels each week focus on two types of designs: space compression type (densely arranged interactive components in narrow areas) and chain triggering type (setting up domino like reaction chains). Players need to repeatedly try and break down the logical relationship between "bolt removal sequence" and "wooden board removal path", and explore the only feasible solution within the framework of gravity rules.
