CrazyGames is set to launch its exciting Crazy Web Multiplayer Jam 2025 from April 25th to May 5th, inviting indie developers worldwide to participate in a 10-day game development marathon. In partnership with Photon, the premier multiplayer service provider, this event will focus on creating innovative web-based multiplayer games. Participants stand a chance to win a share of €10,000 in cash prizes along with premium Photon licenses, which include:
- 500 CCU with Circle Starter for a year (€7,500 value)
- 500 CCU for a year (€1,500 value)
- 100 CCU for a year (€100 value)
The event has straightforward rules: games must be developed and submitted within the jam period and adhere to PEGI 12 rating standards. Beyond these guidelines, developers are encouraged to let their creativity soar!

Since its inception in 2014, CrazyGames has become a leading platform for free online gaming, leveraging HTML5, JavaScript, and WebGI technologies to deliver seamless browser-based gaming experiences across thousands of titles. During the jam, CrazyGames will support participants and offer the chance for winning games to be featured on their platform.
A pre-jam livestream is scheduled for April 24th at 4 pm CEST on YouTube and LinkedIn, where attendees can gain insights into the new WebGL platforms, Fusion and Quantum. Mark Val, Head of Growth at Photon Engine, commented, "Photon has supported multiplayer WebGL for over a decade, and our new Fusion and Quantum samples let you create high-performant multiplayer games easily. We believe a WebGL game will be in the top 20 of the world’s most visited websites in the coming year, and the Crazy Web Multiplayer Jam 2025 is a great opportunity for everyone to innovate on the platform."
Registration for Crazy Web Multiplayer Jam 2025 is free and open to game developers of all experience levels. For more information and to register, visit the official jam page.
