2. Immersive 3D Visual Experience
Features high-definition 3D modeling that restores the authentic textures and structural details of bolts and planks. Supports free rotation and zoom of the perspective, allowing clear observation of complex mechanical layouts for a more immersive and explorative disassembly process.
3. Progressive Difficulty Design
The difficulty progresses from easy to difficult. Early levels enable quick mastery and a sense of achievement, while subsequent levels increase structural complexity and puzzle dimensions. New challenges continuously bring freshness, avoiding repetition and monotony, and are suitable for players of different skill levels.
4. Relaxing and Therapeutic Operation Feedback
Enjoy crisp ASMR sound effects when twisting bolts and smooth animations when unlocking planks, paired with a time-pressure-free puzzle-solving rhythm that delivers strong satisfaction. The controls are simple and intuitive—just select and twist—letting you focus on the puzzle itself to alleviate anxiety.
5. Diverse Creative Level Themes
Levels integrate rich thematic elements, inspired by diverse scenes such as animals, architecture, and works of art. Each level is a unique mechanical maze with exquisite and innovative structures, unlocking more creative puzzle-solving fun.
6. Achievement Unlocking and Point Incentives
Earn points by completing levels and unlock exclusive achievements (e.g., "Flawless Clearance," "Fastest Puzzle Solver"). These non-mandatory additional goals enhance game engagement while bringing sustained a sense of accomplishment and exploration motivation.
Gameplay and Controls
1. Observe & Analyze: Rotate/zoom the 3D view to see the connection between bolts and planks.
2. Core Operation: Click to select a bolt, twist to remove it—planks with no fixed bolts fall off automatically.
3. Logical Key: Disassemble in the right order and plan ahead to avoid getting stuck.
4. Clear & Progress: Remove all planks to clear the level, earn points and unlock the next stage.
Game Guide
As a 3D puzzle game that tests logical thinking, the core of "Bolts and Nuts in 3D!" is not blind disassembly, but unlocking all planks through precise judgment and strategic planning. Master the following skills to quickly advance from a novice to a puzzle expert.
I. Basic Core: Perspective and Priority Principle
After entering a level, the first operation is to use the rotation and zoom functions to scan the entire map and clarify the connection between bolts and planks. Novices tend to fall into the trap of "unscrewing bolts as soon as they see them", but in fact, they need to follow the "isolated point priority" principle - give priority to unscrewing bolts that only fix a single plank, as these bolts are usually the "breakthrough" for clearing the level. For example, if a single plank is only fixed by 2 bolts, unscrewing these 2 bolts will unlock it directly, avoiding wasting time on cross-fixed bolts.

II. Advanced Skills: Reverse Deduction and Marking Method
As the level progresses, the cross-fixing of planks and bolts will become more complex, and the "reverse deduction method" is quite effective at this time. First, observe the core plank that is the hardest to unlock, analyze the fixed bolts it depends on, and then disassemble the outer planks in sequence to pave the way for the core area. If the structure is too complex, you can distinguish the ownership of bolts through "mental marking" - for example, keep in mind that "the red plank is associated with 3 left bolts" to avoid wrong disassembly leading to getting stuck.

Pay attention to the details of physical feedback during operation: if there is stuttering or animation delay when twisting a bolt, it is very likely that the bolt is still fixing other planks, so you need to stop immediately and re-plan the order.
III. Stage-specific Strategy: Clearance Ideas Adapting to Difficulty Gradient
Levels 1-10 are the introductory stage, with structures mainly based on "linear fixing". Following the disassembly order of "from outside to inside" can help you clear the level easily, focusing on familiarizing yourself with perspective operations and bolt feedback rhythm; Levels 11-30 enter the advanced stage, where "circular fixing" and "layered nesting" structures will appear. At this time, you need to first remove the outer auxiliary planks to expose the inner core bolts; After level 30 is the advanced stage, some bolts will be hidden in the perspective blind area, requiring frequent perspective rotation for inspection. It is recommended to unlock the edge area first to expand the field of vision.

IV. Pitfall Avoidance Guide and Point-earning Tips
Novices often make two major mistakes: one is ignoring "hidden fixing" - some planks seem to be fixed by only 1 bolt, but in fact share bolts with adjacent planks; the other is rushing for speed leading to chaotic order. When stuck, you need to calm down and backtrack, undo the recent steps and re-plan. If you want to increase points, you need to pursue "continuous unlocking": immediately lock the next target after disassembling a set of bolts, avoid operation interruptions, and continuously unlocking 3 planks can trigger a point bonus.

Core logic summary: Use perspective to clarify the structure, use isolated points to break the deadlock, use reverse deduction to determine the order, and use stage-specific methods to make strategies. Master these skills, and you can accurately solve all challenges no matter how the level difficulty increases.
