Snort
A vertex-colouring game on graphs where players cannot play adjacent to their opponent's colour.
Rules
Board. An undirected simple graph (no loops or multiedges). Each vertex may be either uncoloured or else coloured blue or red (but not both).
Left moves. Pick an uncoloured vertex that is not adjacent to any red vertices, and colour it blue.
Right moves. Pick an uncoloured vertex that is not adjacent to any blue vertices, and colour it red.
Convention. Classical (normal or misère play).
