CrazyGames and Photon invite indie developers worldwide to participate in Crazy Web Multiplayer Jam 2025, a 10-day game development sprint running from April 25th to May 5th.
Partnering with Photon, the industry-leading multiplayer service, this jam challenges developers to create innovative browser-based multiplayer games. Winners earn shares of €10,000 in prizes plus premium Photon subscriptions including:
- Annual Circle Starter license (500 CCU, €7,500 value)
- Annual 500 CCU license (€1,500 value)

The only requirements: games must be created during the event and meet PEGI 12 rating standards. Beyond that, developers enjoy complete creative freedom.

Since 2014, CrazyGames has dominated browser gaming with its HTML5, JavaScript, and WebGI platform hosting thousands of free games. The company will support participants throughout the jam and publish winning titles.
A pre-event livestream airs April 24th at 4 PM CEST on YouTube and LinkedIn, showcasing Photon's new WebGL platforms: Fusion and Quantum. Mark Val, Photon's Growth Lead, comments: "Our decade of WebGL expertise culminates in Fusion and Quantum - tools simplifying high-performance multiplayer development. We foresee WebGL games breaking into the web's top 20, and this jam offers the perfect innovation platform."
