Play together with family or friends — on the same device or online. Share the game room code and the others can join in.
Online multiplayer with no chat and no way to identify players. Nicknames are generated by the game, so nothing a child writes can ever reach another player.
No tracking, no ads, no advertising identifiers. Single-player runs entirely on your device and sends nothing at all.


Food, exercise and routine cards are your superpowers. The villains are everyday health troubles: fatigue, heartburn, tooth trouble.
The cards come from Idunian. The game itself is a card game — the world is its theme and its artwork, not a level you move through.
Idunian Liberators is an entertainment and educational game. It does not replace advice, diagnosis or treatment from a healthcare professional.
The nutritional content of the cards has been checked against official sources (e.g. Fineli, the Finnish food composition database) and the claims about the villains against reliable sources such as THL, the Finnish Institute for Health and Welfare. For gameplay balance a single card covers only part of its topic: not every food, ailment, weakness and strength can be presented in full, and some are simplified in favour of playability. The content should not be read as comprehensive health guidance.
For health-related questions, always consult a healthcare professional. The full disclaimer is in the game, under About the game.
The texts of this site and of the game in languages other than Finnish were produced with the help of AI. Finnish is the original language, and if the versions differ, the Finnish text is the one that counts.
