Abstract: We introduce the monochromatic transversal game where the players, Alice and Bob, alternately colours vertices of a hypergraph. Alice, who colours the vertices with red, wins the game if she obtains a red transversal; and Bob wins if he does not let it happen, i.e. there exists a monochromatic blue hyperedge. Both players are enabled to start the game and they play optimally. We analyze the game played on clique-hypergraphs of complete graphs, paths, and powers of cycles. For each of these graphs, we show a strategy that allows one of the players to win the game.
