IMPORTANT NOTICE: FRONTEND TEMPLATE ONLY

Please note that this product is a frontend UI/UX game template. It is NOT a real-money gambling game. It does not include a backend server, payment gateways, or a certified RNG (Random Number Generator). The included economy uses simulated demo credits stored locally in the browser. It is intended for social gaming, demonstration purposes, or as a high-quality frontend client ready to be integrated with your own authoritative backend.

Key Features

• Physics-Driven Mechanical Draw: Watch the balls physically agitate, collide, and travel through the glass tube collection system in real-time. The game utilizes custom 2D canvas physics for authentic mechanical movement.
• Procedural Web Audio Engine: Zero external audio files to load. All sound effects—including synth tones, ball clicks, mechanical noise, and win sequences—are procedurally generated using the native Web Audio API for instantaneous, lag-free playback.
• 100% Vanilla JavaScript: Clean, modern ES6 modules with no external framework dependencies (No React, Vue, or jQuery).
• Fluid Responsive Layout: The canvas and UI dynamically calculate their geometry to ensure the glass machine and betting board scale perfectly on any device or aspect ratio.
• Rich Game Mechanics: Players can pick 1 to 10 spots from a 36-number board, with the machine drawing exactly 10 balls per round. Features include a “Quick Pick” auto-selector, stake adjusters, and live payout calculations.
• Turbo Mode: Built-in fast-play toggle skips the physical tube travel animations for players who prefer rapid-fire results.
• State Persistence: Built-in LocalStorage integration saves the player’s demo balance, current bets, chosen numbers, and audio preferences between sessions.
• Accessibility Ready: Respects user device settings by automatically detecting prefers-reduced-motion to tone down particle emitters and background animations.
• Progressive Web App (PWA) Capable: Includes mobile-web-app meta tags, enabling full-screen, app-like experiences when saved to an iOS or Android home screen.
• Developer API Hooks: Exposes a window.NeonKeno global object, making it incredibly easy to read game states or wire up a server-authoritative RNG for backend integration.
