The Discrepancy Game

The Discrepancy game is played on a hypergraph H by two players, Balancer and Unbalancer, who color the still uncolored vertices of H alternately, say Balancer using RED and Unbalancer using BLUE. Balancer's goal is that at the end of the game there are roughly the same number of red and blue vertices in every edge. Unbalancer's goal is to make an edge unbalanced. We give a criterion and strategy for Balancer to win.

(Joint work with N. Alon, M. Krivelevich and J. Spencer)
