Welcome to the Transformice Wiki!

Transformice is a free online multiplayer game created by Melibellule and Tigrounette owned by Atelier 801. The objective of this game is to collect cheese playing as a mouse character, and take it back to the hole in exchange for a currency, not surprisingly named cheese. This cheese can be spent on items, map creation or other things, such as starting up a tribe of mice. In the majority of maps, a shaman is needed to aid in getting the mice to the cheese and into the mouse hole, using wide selection of tools that can be conjured by the shaman to create various contraptions to get to the cheese.
