Welcome to Bot Bowl


Bot Bowl is an annual AI competition in the board game Blood Bowl (Games Workshop). Blood Bowl is a fully-observable, stochastic, turn-based, modern-style board game with a grid-based game board. At first sight, the game ought to be approachable by numerous game-playing algorithms. However, as all pieces on the board belonging to a player can be moved several times each turn, the turn-wise branching factor becomes overwhelming for traditional algorithms. Additionally, scoring points in the game is rare and difficult, which makes it hard to design heuristics for search algorithms or apply reinforcement learning.

We see Blood Bowl as the next board game challenge for AI. You can read more about this in our paper Blood Bowl: A New Board Game Challenge and Competition for AI.

The Bot Bowl competitions are organized by Niels Justesen and the repoistory is hosted here on GitHub https://github.com/njustesen/botbowl.
