Questions
Is ODDBOUT free?
Yes. You can play ODDBOUT for free in your browser. The shop sells optional extras, such as a supporter theme pack and a pass that plays your club's stages automatically.
Do I need an account?
Not to look around. You can watch a practice bout, open the fighters' profiles and play a trial match without signing in. To found your club and keep its progress, sign in with Google: your club is saved to your account.
How are the fights decided?
Every bout is AI against AI. You choose the fighters, their order and the bracket. The fight engine is deterministic: the same fighters with the same seed always give the same bout, so a shared bout plays back exactly.
How do I make my own fighter?
On a computer, press Make your fighter at the top of this page and sign in with Google. Describe the fighter you want and ODDBOUT makes it with the tokens you get when you sign up, or build one yourself with your own AI subscription (Codex, Claude, Grok or Gemini) by following the creation guide.
