Reference Prompt

Create a Match-3 puzzle game (Bejeweled/Candy style) as ONE self-contained HTML file.
Genre: swap adjacent gems on a grid; match 3+ same color to clear and score.
Board: 8×8 grid; 5–6 gem colors with distinct shapes/colors.
Swap: click/tap two orthogonally adjacent tiles; invalid swap animates back.
Gravity: tiles fall; new tiles spawn from top; cascades count combo multiplier.
Goal: reach target score in N moves OR endless high-score mode (pick one).
Special tiles (optional): 4-match line bomb, 5-match color clear.
HUD: score, moves left, goal progress.
Hint (optional): wiggle a valid move after idle 10s.
No matches at start; shuffle if no moves (optional).
Touch-friendly tile hit targets.
Juice: pop particles on clear; satisfying swap tween.
Title screen; game over when moves exhausted (if limited).
Detect matches only after player swap (not on spawn unless cascade).
Output: full HTML only (<!DOCTYPE html> ... </html>), no markdown fences.
Stack: inline CSS + inline JavaScript only. No npm, no build step, no local file deps.
Rendering: Canvas 2D (preferred) or DOM; must run in desktop and mobile browsers.
Controls — keyboard: document in a title/HUD overlay; R to restart.
Controls — touch: on-screen buttons ≥ 44px; prevent page scroll while playing.
Flow: title → play → win or lose → restart without reloading the tab.
HUD: score and clear objective; high-contrast text on small screens.
Do not use alert() for main UI; use canvas/DOM overlays.
Do not use onclick= inline handlers; use addEventListener.
Do not access parent/top window or iframe sandbox escape.
Do not depend on external URLs for core gameplay assets.
Optional Web Audio after first user gesture; fail silently if blocked.
Smoke-test: first 30 seconds are playable, not menu-only.

Tips for AI Agents

Difficulty: medium — Requires state management, grid/rotation logic, level transitions, and polish.

Always include Web Audio API for sound effects and mobile touch controls for broader playability. Canvas 2D is preferred over DOM manipulation for game rendering.
