Launching on CrazyGames

All game submissions are carefully reviewed by our QA team according to our technical and quality requirements. Please take the time to read our requirements section to ensure your game submission is accepted.

Starting June 23, 2025, games will follow a new two-stage launch process: Basic Launch and Full Launch. The goal of this new process is to shorten the initial launch timeline and evaluate real-world performance before proceeding to a global release. You can learn more about how we select games for launch on our FAQ page.

The phases are described below:

Basic Launch
Basic Implementation		 Full Launch
Full Implementation
  • Test your game on our platform with a limited audience for a temporary 2-week period.
  • Requires Basic Implementation; no CrazyGames-specific integration and only Basic QA review.
  • Monetization (video ads, banners, in-game purchases) is disabled.
  • Proceed to Full Launch if metrics are good.
  • Your game is selected for global release.
  • Requires Full Implementation of CrazyGames requirements, including a Full QA review.
  • Monetization is enabled and you start receiving revenue share.
  • During integration, the Basic version remains available to its initial limited audience.

Check our requirements section for detailed requirements for each phase. Our QA tool will guide you through the submission and review process step by step.

Progression to the Full Launch stage is based on key engagement metrics - average playtime, conversion to gameplay, and retention. These metrics will be benchmarked against other games on the platform. During the Basic Launch stage, you'll have the opportunity to monitor performance and gather user feedback. At the end of this 2-week period, you’ll be notified about the next steps:

  • If all metrics meet or exceed benchmarks, you are invited to update your game. After implementing Full Implementation requirements, you can then submit the new version for Full Launch.
  • If some metrics meet benchmarks, you may be invited to improve your game and request another Basic Launch period.
  • If most metrics fall below benchmarks, your game unfortunately can’t proceed to Full Launch. If you wish to submit it again, you need to submit as a new game including significant improvements.

In some cases, such as multiplayer titles that require a larger audience or games already published elsewhere and specifically invited by our team, you may bypass the Basic Launch and proceed directly to the Full Launch. Additionally, games submitted before June 23, 2025, will follow the previous process and go straight to Full Launch.

SDK

Our SDK bridges the gap between your web game and CrazyGames. Furthermore:

  • It is easy to integrate, with simple one-time integration
  • You can earn revenue through user-friendly ads
  • Your game integrates perfectly with our platform
  • The documentation is simple to follow

To start using the SDK pick the one corresponding to the technology you are using. If your technology isn't explicitly listed, you can usually manage at least basic integration through the HTML5 version. Most game engines that support WebGL also have a way of interacting with JavaScript when running in browser.

Make sure to check about our requirements before you start integrating the SDK.

You can integrate our SDK with any common game development framework. We currently have games live developed with Unity, Defold, Godot, Phaser, PlayCanvas, Construct, Pixi.js, BabylonJS, and many other frameworks.
