Home of Kriegsspiel
The International Kriegsspiel Society is the world’s largest, online association dedicated to Kriegsspiel. It unites over 1,600 members from all over the world in the passion of studying, discussing and playing Kriegsspiel.
The International Kriegsspiel Society is an open, welcoming, inclusive and diverse community. Wargaming and especially Kriegsspiel as we understand it, focus on people, diversity of thought and perspectives, on learning from others, and reflecting about preconceptions and established concepts of thought.

The International Kriegsspiel Society endorses the Derby House Principles for inclusion and diversity in professional wargaming.
The International Kriegsspiel Society is open to everyone interested in the game, no matter the experience level or background. Kriegsspiel is easy to play, hard to master, as players don’t need to know any rules!
Our mission is to preserve Kriegsspiel, to make it accessible to enthusiasts, hobbyists and practitioners, to provide extensive resources to study and play Kriegsspiel, and to contribute to the development of new Kriegsspiel systems.
In order to reach these goals, we encourage every person interested to learn more about and play Kriegsspiel to join the community, no matter their experience level, social, educational, national or religious background, age, or gender. Although we keep being positively surprised by the communication culture of our community, our moderation policy is dedicated to firmly ensure that this remains to be the case. We pledge to keep the IKS a space where you can be you, without the toxicity or inappropriate attention.
We hope to welcome you soon!
