Combinatorial games on multi-type Galton-Watson trees

When normal and misère games are played on bi-type binary Galton-Watson trees (with vertices coloured blue or red and each having either no child or precisely $2$ children), with one player allowed to move along monochromatic edges and the other along non-monochromatic edges, the draw probabilities equal $0$ unless every vertex gives birth to one blue and one red child. On bi-type Poisson trees where each vertex gives birth to Poisson$(λ)$ offspring in total, the draw probabilities approach $1$ as $λ\rightarrow \infty$. We study such \emph{novel} versions of normal, misère and escape games on rooted multi-type Galton-Watson trees, with the "permissible" edges for one player being disjoint from those of her opponent. The probabilities of the games' outcomes are analyzed, compared with each other, and their behaviours as functions of the underlying law explored.
