Please use Three.js to generate a **mobile-first game** with the theme "**Nuts and Bolts: Screwing Puzzle**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: 2.5D aesthetics. Use an **Orthographic Camera** to mimic the flat, vector-art look of the reference screenshot, but with 3D depth for the physics interactions. The style should be cartoonish, vibrant, and clean. * **Key Models**: * **The Board**: A wooden texture background plane. * **Plates**: Rounded rectangular strips in bright colors (Yellow, Green, Red, Blue). They should look like painted metal or hard plastic with slight specular highlights. * **Screws**: Gold/Brass colored models with a distinct cross-head (Phillips style) and a threaded shaft. * **Holes**: Circular cutouts in the plates and the background board. * **Lighting**: Soft ambient light combined with a directional light to cast subtle drop shadows from the plates onto the wood background, emphasizing depth. * **Mobile Optimization**: Use low-poly cylinders for screws. Reuse geometries (InstancedMesh) for screws and plates where possible. Textures should be compressed. ### 2. Audio Requirements * **BGM**: A light, thinking-style track. Playful and acoustic, utilizing pizzicato strings or marimba to encourage puzzle-solving without being distracting. * **Sound Effects (SFX)**: * **Unscrewing**: A satisfying mechanical "ratchet" or twisting sound. * **Metal Clink**: When a screw is placed into a new hole. * **Wood/Metal Thud**: When a loose plate falls and hits the bottom of the screen or other objects. * **Success Chime**: A bright, ascending sound when the board is cleared. ### 3. Gameplay Loop * **Objective**: Clear the board by removing all plates. * **Mechanics**: * **The Constraint**: The player has a limited number of "spare holes" (either on a dedicated tray or empty holes on the board itself). * **The Interaction**: 1. Player taps a screw currently pinning a plate. 2. Player taps an empty hole. 3. The screw unscrews (animates rotation and upward movement), flies to the new hole, and screws in. * **Physics Logic**: * If a plate has **0 screws**, it becomes a dynamic physics body and falls off the screen due to gravity. * If a plate has **1 screw**, it acts as a hinge joint/pivot, swinging freely based on gravity and collisions with other plates. * If a plate has **2+ screws**, it remains static (kinematic). * **Win Condition**: All metal plates have fallen off the screen. * **Fail Condition**: No empty holes remain to move screws, and plates are still stuck. ### 4. Mobile Controls & Interaction * **Input**: Raycasting for touch events. * **Tap**: Select a screw (highlight it with a glowing outline or distinct color). * **Tap**: Select a target empty hole to move the selected screw. * **Orientation**: **Portrait Mode** (Vertical) to accommodate the falling mechanics and typical mobile puzzle layout. * **Visual Feedback**: * When a screw is selected, show a "pulse" effect or a particle emitter (like the stars in the screenshot). * Invalid moves (tapping a filled hole) should trigger a small "shake" animation of the screw. * **UI Layout**: * Top: Level Progress Bar. * Bottom: "Reset Level" and "Hint" buttons (minimum 44x44px touch targets). * Ensure UI does not overlap with the main physics play area. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Nuts and Bolts: Screwing Puzzle is a captivating brain game that challenges players to think strategically while unscrewing and disassembling intricate metal structures. This innovative puzzle game combines physics-based mechanics with logical thinking, creating an engaging experience that tests your problem-solving abilities.

In this unique puzzle adventure, you'll navigate through increasingly complex mazes of tangled iron sheets, bolts, nuts, and metal plates. Each level presents a new challenge where every screw placement matters, and one wrong move could leave you stuck.

Core Features

Strategic Puzzle Solving

The game's core mechanic revolves around strategic thinking. You must carefully analyze each structure before making your moves, as you have limited spots to place removed screws. This constraint adds a layer of complexity that transforms simple unscrewing into a brain-teasing challenge.

Progressive Difficulty Levels

Starting with simple structures, the game gradually introduces more complex assemblies with multiple layers, interconnected parts, and tricky screw placements. Each level builds upon previous knowledge while introducing new mechanics and challenges.

Physics-Based Gameplay

The realistic physics engine ensures that structures behave naturally when screws are removed. Metal plates fall realistically, creating satisfying chain reactions that reward clever thinking and precise execution.

Helpful Hints and Tools

When puzzles become particularly challenging, the game provides various hints and assistance tools. These features ensure that players never feel completely stuck while maintaining the satisfaction of solving puzzles independently.

Game Mechanics

Limited Screw Placement

The most distinctive feature is the limited number of spots available for placing removed screws. This mechanic forces players to think several moves ahead, similar to chess, making each decision crucial to success.

Structural Analysis

Before unscrewing anything, players must analyze how different parts are connected. Understanding these relationships is key to determining the correct sequence of screw removal.

How to Play

The gameplay is elegantly simple yet deeply strategic:

  1. Observe the Structure : Study the metal assembly and identify how parts are connected
  2. Plan Your Moves : Determine the optimal sequence for removing screws
  3. Click and Place : Click on screws to remove them and place them in available spots
  4. Watch the Physics : Observe how structures collapse and reorganize as screws are removed
  5. Complete the Puzzle : Successfully disassemble the entire structure to advance

Strategic Tips

  • Always examine the entire structure before making your first move
  • Look for screws that support multiple parts
  • Consider which parts need to fall first to access other screws
  • Use hints wisely when facing particularly challenging levels

Platform Compatibility

Nuts and Bolts: Screwing Puzzle offers excellent cross-platform compatibility:

  • Desktop Computers : Full-featured experience with mouse controls
  • Mobile Devices : Optimized touch controls for smartphones and tablets
  • Web Browsers : No download required - play instantly online
  • Universal Access : Compatible with iOS, Android, Windows, and Mac systems

Why Play This Game

This puzzle game offers several compelling reasons to play:
