Please use Three.js to generate a **mobile-first game** with the theme "Sudoku Calendar". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Minimalist "Zen" aesthetic. Use a soothing, dynamic gradient background that shifts slowly over time (referencing the Deep Purple to Sunset Orange gradient in the source image). * **3D Elements**: * The Sudoku Grid should be a floating 3D board with rounded edges. * Each cell (tile) is a slightly beveled cube with soft shadows. * **Text**: Use a clean, sans-serif font (e.g., Roboto or Montserrat) rendered as 3D text or high-resolution textures on the tiles. * **Effects**: * **Selection**: When a cell is selected, it should slightly elevate (translate Z-axis) and glow. * **Completion**: When a 3x3 box, row, or column is completed, emit a subtle particle burst (confetti or glowing orbs) in the matching color palette. * **Mobile Optimization**: Use `InstancedMesh` for the 81 grid tiles to reduce draw calls. Use basic materials with baked lighting or simple Phong materials to maintain 60 FPS on mobile browsers. ### 2. Audio Requirements * **BGM**: A generative, ambient Lo-Fi or soft piano track. It must be non-repetitive and aid concentration. * **Sound Effects (SFX)**: * *Tap/Select*: A soft "wood block" or "bubble pop" sound. * *Number Entry*: A pleasant "click" with varying pitch based on the number value (1=low pitch, 9=high pitch). * *Error*: A subtle, non-aggressive low thud or dull tone (avoid harsh buzzers). * *Victory*: A satisfying major chord arpeggio. ### 3. Gameplay Loop * **Menu System**: A 3D scrolling "Calendar" view where the player selects a date to unlock a puzzle. Include a "Quick Play" button for a random generated puzzle. * **Core Mechanics**: * Standard 9x9 Sudoku rules. * **Difficulty**: Easy (remove 30 numbers), Medium (remove 40), Hard (remove 50). * **Logic**: Prevent the user from entering a number if it violates the basic rules (optional "Strict Mode") or highlight conflicts in red immediately after entry. * **Tools**: * **Pencil Mode**: Toggle to allow entering multiple small candidate numbers in one cell. * **Hint**: Auto-fill a selected cell (with a visual cooldown). * **Win Condition**: The board is full and valid. Trigger a victory animation where the board spins and tiles wave. ### 4. Mobile Controls & Interaction * **Orientation**: **Portrait Mode Only** (Vertical layout is essential for Sudoku on mobile). * **Layout**: * Top 60%: The 3D Sudoku Board. Camera should be fixed but allow slight parallax tilt based on device gyroscope (if available) or touch drag. * Bottom 40%: The Control Zone (Thumb friendly). * **Input Method**: 1. **Tap Board**: User taps a 3D tile on the grid to select it. The camera creates a subtle dolly-zoom to focus on the selected area. 2. **Numpad**: A 1-9 virtual keypad fixed at the bottom of the screen. * **Visual Feedback**: * **Highlighting**: When a user selects a cell containing "5", all other "5"s on the board should highlight. The respective row, column, and box should also have a faint highlight. * **Vibration**: Use `navigator.vibrate(10)` for light haptic feedback on every valid number entry. * **Invalid Move**: If a user places a wrong number (in "Check Mode"), the tile should shake horizontally (sine wave animation). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
