Powder Game on Dan-Ball: Runs Natively in HTML5/JavaScript, No Plugins Required

Zero plugins required. Powder Game (and all Dan-Ball titles) run entirely on standard, modern web technologies:

• HTML5 Canvas for rendering.
• JavaScript (ES6+) for simulation logic.
• WebAssembly (WASM) in newer versions for high-performance physics.

Requirements

• Modern Browser: Chrome 60+, Firefox 55+, Edge 79+, Safari 13+ (any browser updated since 2018).
• JavaScript Enabled: On by default. Verify in Firefox at about:preferences#privacy or Chrome Settings > Site Settings > JavaScript.
• WebGL (Optional): Used for shaders in version 3+. Supported universally.
• Decent CPU: Simulation is single-threaded JavaScript. Large grids (400x300) with heavy particle counts need ~2 GHz single-core performance.

Troubleshooting "Not Working"

1. Update Your Browser. Old versions lack Canvas 2D / WASM support.
2. Disable Extensions. Ad blockers (uBlock), script blockers (NoScript), and privacy tools (Privacy Badger) frequently break the game script. Whitelist dan-ball.jp.
3. Clear Cache/Cookies for dan-ball.jp.
4. Try Incognito/Private Window. Rules out extension conflicts.
5. Mobile: Use Chrome (Android) or Safari (iOS). Touch controls work natively.
