Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Wordoku". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Clean, minimalist "Puzzle Blue" aesthetic. The board should look like a sleek, modern interface rather than a piece of paper. * **Color Palette:** Use the colors from the reference image: White (`#FFFFFF`) for empty tiles, Light Blue (`#E0F7FA`) for alternating 3x3 zones, and Deep Sky Blue (`#0277BD`) for the currently selected cell or highlighted numbers. * **3D Models:** * **The Grid:** Instead of a flat plane, create a 9x9 grid of slightly beveled, rounded cubes (Tiles). * **Text:** Use a clean sans-serif font (loaded via `FontLoader`) extruded slightly to sit on top of the tiles. * **Lighting & Camera:** * Use an Orthographic Camera to maintain the puzzle grid layout without perspective distortion, ensuring lines remain parallel. * Soft ambient lighting plus a directional light to cast subtle drop shadows under the tiles, giving depth to the board. * **Performance:** Use `THREE.InstancedMesh` for the 81 grid tiles to ensure 60 FPS performance on mobile devices. ### 2. Audio Requirements * **BGM:** A "Focus/Zen" track. Soft, repetitive ambient electronic or acoustic piano music that aids concentration. * **SFX:** * **Tap/Select:** A crisp, short "bubble" or "plastic click" sound. * **Place Letter:** A satisfying "thud" or "snap" sound. * **Error/Invalid Move:** A gentle, low-pitched "error" tone (avoid harsh buzzers). * **Row/Column Completion:** A subtle chime. * **Game Win:** A bright, ascending major scale arpeggio. ### 3. Gameplay Loop * **Initialization:** * Generate a valid, solvable 9x9 Sudoku grid algorithmically. * Select a random 9-letter isogram word (a word with no repeating letters, e.g., "COPYRIGHT", "WORKPLACE") to replace the standard numbers 1-9. * Remove random cells based on a difficulty setting (start with "Easy" - removing ~30 cells). * **Core Mechanics:** * **Selection:** Player taps a cell on the grid. * **Input:** Player taps a letter from the "Input Strip" (the 9 unique letters of the chosen word) located at the bottom of the screen. * **Validation:** * **Real-time Check:** If the placed letter violates Sudoku rules (already exists in the row, column, or 3x3 subgrid), highlight the conflicting cells in Red and play the Error SFX. * **Note Mode (Optional but recommended):** A toggle to allow placing small "pencil mark" candidates. * **Win Condition:** The grid is completely filled with no rule violations. Trigger a victory animation (tiles spin or wave). ### 4. Mobile Controls & Interaction * **Screen Orientation:** **Portrait Mode** only. This allows the 9x9 grid to sit in the top 60% of the screen and the controls in the bottom 40%. * **Input Handling:** * Use `THREE.Raycaster` mapped to touch events for selecting grid cells. * **The Input Strip:** Create a UI overlay (HTML/CSS or Three.js Sprites) at the bottom containing the 9 available letters as large, thumb-friendly buttons (minimum touch target 48x48px). * **Visual Feedback:** * **Highlighting:** When a cell is selected, highlight all other instances of that same letter on the board (e.g., if "W" is in the selected cell, light up all "W"s). * **Animation:** When a letter is placed, the tile should depress slightly (scale down on Z-axis) and spring back up (elastic easing). * **Haptics:** Trigger `navigator.vibrate(10)` (light impact) on every valid letter placement. Trigger a double pulse on error. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Wordoku is a fascinating twist on the beloved Sudoku puzzle that replaces numbers with letters, creating an entirely new gaming experience. This clever variation challenges players to think about both logical placement and word formation simultaneously, making it perfect for word game enthusiasts and puzzle lovers alike.

Unlike traditional number-based Sudoku, Wordoku requires you to fill a 9x9 grid using the nine letters of a specific word. Each letter must appear exactly once in every row, column, and 3x3 sub-grid, just like classic Sudoku, but with the added challenge of working with alphabetic characters.

Core Features

Unique Word-Based Gameplay

Wordoku transforms the familiar Sudoku experience by incorporating vocabulary and spelling skills. Players must consider not just the logical placement of letters but also their relationship to form meaningful words.

Brain Training Benefits

This game offers excellent cognitive exercise by combining: - Logical reasoning from traditional Sudoku mechanics - Vocabulary skills through letter recognition and word formation - Pattern recognition for strategic placement - Memory enhancement by remembering letter positions

Accessible Design

The clean, intuitive interface makes Wordoku easy to understand for both Sudoku veterans and newcomers. The blue and white grid design provides clear visual separation between cells and regions.

Progressive Difficulty

While maintaining the core 9x9 grid structure, different word combinations create varying levels of challenge, ensuring the game remains engaging for players of all skill levels.

Game Mechanics

Wordoku follows the fundamental Sudoku rules with a linguistic twist:

  1. Grid Structure : Standard 9x9 Sudoku grid divided into nine 3x3 sub-grids
  2. Letter Placement : Each cell contains one letter from the target 9-letter word
  3. Row Rule : Each row must contain all nine letters exactly once
  4. Column Rule : Each column must contain all nine letters exactly once
  5. Sub-grid Rule : Each 3x3 section must contain all nine letters exactly once

How to Play

Getting Started

When you begin a Wordoku puzzle, you'll see a partially filled 9x9 grid with some letters already placed as clues. Your objective is to complete the grid following the placement rules.

Letter Placement Strategy

  1. Analyze the given letters to understand which 9-letter word is being used
  2. Identify empty cells where only one letter can logically fit
  3. Use elimination to narrow down possibilities for each cell
  4. Cross-reference rows, columns, and sub-grids to find contradictions
  5. Work systematically through the grid, filling in certain placements first

Tips for Success

  • Start with cells that have the fewest possible letter options
  • Pay attention to letter frequency within the target word
  • Use pencil marks (mental or physical) to track possible letters for each cell
  • Look for patterns and letter combinations that form common word fragments
