HTML provides the page and a canvas element, CSS positions and styles that canvas plus any DOM-based UI, and JavaScript runs the game loop, draws frames via the Canvas or WebGL API, handles input, and manages logic and state.<\/strong><\/p>\n

The three layers split cleanly by job. HTML defines the page structure and gives the game a place to live, usually a <canvas><\/code> element (see MDN’s Canvas API<\/a> docs) or a WebGL context (WebGL API). CSS positions and styles that canvas plus any surrounding UI – menus, score overlays, buttons built as regular DOM elements. JavaScript does the actual work: it runs the game loop, reads input, updates state, and draws each frame to the canvas or WebGL context. If you’re building an engine project rather than hand-coding this, Unity’s WebGL export (Unity manual: Web<\/a>) and Godot’s web export (Godot docs: exporting for the Web<\/a>) generate this HTML\/CSS\/JS scaffolding for you, and both let you call back into browser JavaScript when you need browser-only features like storage or ad SDKs.<\/p>\n

When targeting multiple web destinations, Playgama Bridge is an open-source SDK (LGPL-3.0) that adapts one HTML5 build to 25+ platforms. Publishing through Playgama lets you upload via the Developer Console to reach playgama.com and 100+ distribution partners, while the Playgama MCP server automates game setup, build uploads, and sandbox testing directly from tools like Claude Code or Cursor.<\/p>\n

Once the build works locally, publishing it means putting that HTML\/CSS\/JS bundle somewhere players can reach. Options include Poki (developers.poki.com<\/a>), CrazyGames (developer.crazygames.com<\/a>), GameDistribution, itch.io, and playgama.com<\/a>, where you upload via the Developer Console at developer.playgama.com, get test feedback within 24 hours, and get distributed to partner portals alongside the main site.<\/p>\n
