Game Submission Guidelines & Technical Specs

OnlineRealGames.com HTML5 & WebGL Build Standards

Entry Point: The ZIP must contain an index.html file (either in the archive root or directly inside a single top-level folder).
Archive Limits: Maximum ZIP compressed size is 300 MB; maximum extracted size is 800 MB; maximum file count is 8,000 files.
Relative Asset Paths: All scripts, stylesheets, audio, images, and WebAssembly chunks must use relative paths (e.g. src="assets/game.js" or ./game.js), never hardcoded domain paths.
Prohibited Server Files: Do NOT include server-side scripts (.php, .py, .sh, .cgi, .htaccess, etc.). The submission validator will automatically reject packages containing server executables.

Aspect Ratios: Standard widescreen (16:9), flexible responsive canvas, or portrait orientation are supported.
Touch & Keyboard: If your game is designed for mobile players, provide full touch controls and on-screen buttons. If keyboard controls are required, specify this in the controls metadata.
Fullscreen: Games should cleanly adapt when the player triggers browser fullscreen or iframe resizing.

Thumbnails (all three required): thumb_1 512×310 px (landscape card), thumb_2 512×512 px (square) and thumb_3 384×512 px (portrait) — JPEG, PNG or WebP up to 5 MB each. Avoid small, unreadable text on the thumbnail.
Screenshots: Up to 5 high-resolution gameplay screenshots highlighting actual in-game action.

Games run inside an isolated iframe sandbox with: allow-scripts allow-same-origin allow-pointer-lock.
Games must NOT attempt to access parent window cookies, localStorage of the host domain, or break out of iframe boundaries.
