Crazy Games, Photon Kick Off 10-Day Global Web Multiplayer Jam 2025

CrazyGames is set to launch its Crazy Web Multiplayer Jam 2025 this week, running from April 25th to May 5th. This 10-day event, held in partnership with Photon, the leading multiplayer service provider, invites indie developers worldwide to participate in a thrilling game development marathon focused on creating innovative web-based multiplayer games.

Participants in the jam will have the chance to compete for a total of €10,000 in cash prizes, along with premium Photon licenses. The available licenses include:

• 500 CCU with Circle Starter for a year (valued at €7,500)
• 500 CCU for a year (valued at €1,500)
• 100 CCU for a year (valued at €100)

The only strict requirements for the event are that the games must be developed and submitted within the jam period and must adhere to PEGI 12 rating standards. Beyond these rules, developers have the freedom to explore their creativity and innovation.

Since its inception in 2014, CrazyGames has become the go-to platform for free online gaming, leveraging technologies like HTML5, JavaScript, and WebGI to deliver seamless browser-based gaming experiences across thousands of titles. In collaboration with Photon, CrazyGames will provide support throughout the event and offer winners the chance to have their games published on their platform.

To kick off the jam, a pre-event livestream will be hosted on YouTube and LinkedIn on April 24th at 4 pm CEST. This session will introduce two new WebGL platforms, Fusion and Quantum. Mark Val, Head of Growth at Photon Engine, emphasized the significance of these platforms, stating, "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 good opportunity for everyone to innovate on the platform."

Registration for the Crazy Web Multiplayer Jam 2025 is free and open to game developers of all skill levels. Interested participants can find more information and register on the official jam page.
