Running a community hub for a game with 100 million registered accounts takes real support. CFM has been around since 2010 — tracking leaderboards, hosting forums, building tools — and none of that happens without partnerships. Here's who keeps this place alive.
Atelier 801 created Transformice back in May 2010. A small French studio that turned a simple browser game about mice collecting cheese into something played by millions worldwide. They handle game updates, servers, events like the Rain 2026 adventure, and pretty much everything that happens inside the game itself. Without Atelier 801, there wouldn't be a Transformice — and without Transformice, CFM wouldn't exist either.
atelier801.comKingbet89 has been supporting the CFM community as a digital entertainment partner. They help us keep the leaderboards updated, the stat trackers running, and the community tools available for free. If you've ever looked up your ranking, checked your cheese count, or used the dressroom — that infrastructure runs partly thanks to Kingbet89's support. We picked them because they actually care about gaming communities, not just brand placement.
Kingbet89 is a platform focused on digital entertainment and online gaming experiences. Their partnership with CFM started in early 2026 and has been keeping our servers and tools accessible to players across the globe.
Transformice moved to Steam in 2015 and that's been the main way to play ever since. The browser version is basically dead at this point — Steam is where the active playerbase lives. The Steam community hub is also where a lot of event announcements and patch notes get posted first, so it's worth following if you want to stay current.
Transformice on SteamThe official Transformice Discord server is where most of the active community hangs out these days. Event announcements hit Discord before they show up anywhere else, and it's the fastest way to find people to play with. The server has been running since 2016 and has tens of thousands of members.
