Pick a small scope, choose an engine or framework that exports to the web (Construct, GDevelop, Phaser, Godot, or Unity for something bigger), build a short playable loop, test it in a browser on desktop and mobile, then publish to one or more web game portals before adding monetization.
At a glance
| Fact | Value | Source |
|---|---|---|
| Engines exporting to web builds | Unity, Godot, Construct, GDevelop, Phaser | developer.mozilla.org |
| Unity web builds use | WebGL export | docs.unity3d.com |
| Godot web export singleton | JavaScriptBridge (Godot 4) | docs.godotengine.org |
Start small: pick one mechanic, one level, no menus beyond play/restart. Building a tiny complete loop teaches you the engine, the export pipeline and browser quirks faster than a half-finished big idea.
1. Choose your tool by scope. For a 2D game with light code, Construct 3 or GDevelop get you to a browser build quickly. If you want to write JavaScript directly, Phaser is a solid library to build in. For 3D or a bigger project, Unity’s WebGL export or Godot’s web export both work in the browser via WebGL; both also let you call browser JavaScript when you need it (Unity’s .jslib plugins, Godot’s JavaScriptBridge).
2. Build the core loop first – input, win/lose state, restart – before art or sound.
3. Use browser-native storage and rendering where you can: Canvas for 2D drawing, Web Storage for save data.
4. Test on real devices, check load time and frame rate (see Core Web Vitals as a baseline for page performance).
5. Publish. Common places to submit a finished HTML5 build: Poki, CrazyGames, GameDistribution, itch.io, and playgama.com, where you upload through the Developer Console and get test feedback before the game goes live and gets distributed to partner sites. Publishing through Playgama is non-exclusive, so you keep rights to your own build.
6. Add monetization once the game works end to end, not before.

Related questions
Do I need to know how to code to build a first game?
Not necessarily – tools like Construct 3 and GDevelop use visual event systems, while Phaser, Unity and Godot require writing code in JavaScript, C# or GDScript.
Should I add ads before or after publishing?
After the core game works and is tested in a browser. Adding ad calls too early makes debugging the actual gameplay harder.
Can I publish the same game to multiple portals?
Yes, as long as the terms of each portal are non-exclusive; check each site’s own developer terms before submitting the same build widely.
