Please use Three.js to generate a **mobile-first game** with the theme "**Ultimate Sudoku**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Clean, minimalist, and readable aesthetic suitable for long play sessions. The game should use a bright, high-contrast color palette inspired by the screenshot: a white background, light gray grid lines, and bold orange for the title/highlights. * **3D Elements:** * **The Board:** Instead of a flat 2D canvas, render the 9x9 Sudoku grid as a slightly raised, 3D tile board floating in space. Each cell is a separate cube or rounded-edge tile. * **Numbers:** Numbers (1-9) should be 3D text meshes or high-quality textures applied to the top face of the tiles. * **Selection State:** When a cell is selected, the tile should slightly elevate (animate up) and glow with a soft blue outline. * **Camera:** A fixed perspective camera (orthographic or slight perspective) positioned directly above or at a slight angle to the board to maximize visibility while maintaining a 3D feel. * **Performance:** Use instanced meshes for the grid tiles to ensure 60fps performance on mobile devices. Keep geometry simple (low-poly) for the tiles. ### 2. Audio Requirements * **BGM (Background Music):** A calm, ambient, lo-fi "study beat" or Zen-like piano track. It should be non-intrusive and loop seamlessly to aid concentration. * **Sound Effects (SFX):** * **Selection:** A soft, wooden "clack" or "pop" sound when tapping a cell. * **Number Entry:** A satisfying "pencil scratch" or digital "blip" when a number is confirmed. * **Error:** A subtle, low-pitched "thud" or buzzer if the player inputs a number that conflicts with Sudoku rules (if instant validation is on). * **Completion:** A harmonious chime or ascending scale when a row, column, or 3x3 box is successfully filled. * **Victory:** A celebratory fanfare with confetti sound effects upon completing the puzzle. ### 3. Gameplay Loop * **Core Mechanic:** Standard Sudoku rules apply. The player must fill a 9x9 grid with digits so that each column, each row, and each of the nine 3x3 subgrids that compose the grid contain all of the digits from 1 to 9. * **Difficulty Levels:** Implement a simple difficulty generator (Easy, Medium, Hard) that determines how many numbers are pre-filled at the start. * **Validation:** * **Real-time:** Highlight conflicting numbers in red immediately if the user places a duplicate in a row/col/box. * **Note Mode:** Allow users to toggle a "Pencil/Note" mode to place small, temporary candidate numbers in a cell without committing. * **Victory Condition:** The game is won when the entire board is filled correctly with no conflicts. Trigger a particle effect explosion from the board upon winning. ### 4. Mobile Controls & Interaction * **Touch Controls:** * **Grid Interaction:** Tapping a cell on the 3D board selects it. The camera should not pan or zoom; the board fits the screen width. * **Numpad UI:** A large, touch-friendly number pad (digits 1-9) must be fixed at the bottom of the screen. Buttons should be at least 44x44px (or larger) for thumb accessibility. * **Functional Buttons:** Include "Undo," "Erase," and "Note Mode" toggle buttons near the numpad. * **Screen Orientation:** **Portrait Mode** is mandatory. The layout should be: Top = Timer/Score, Middle = 3D Board, Bottom = Numpad/Controls. * **Haptic Feedback:** Trigger a light vibration (using `navigator.vibrate` if available) when selecting a cell or placing a number to simulate tactile response. * **Visual Feedback:** When a number (e.g., '5') is selected on the numpad or board, highlight all other '5's currently on the board to help the player scan patterns. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
