We introduce and study Maker/Breaker‐type positional games on random graphs. Our main concern is to determine the threshold probability p ℱ for the existence of Maker's strategy to claim a member of ℱ in the unbiased game played on the edges of random graph G ( n, p ), for various target families ℱ of winning sets. More generally, for each probability above this threshold we study the smallest bias b such that Maker wins the (1 : b ) biased game. We investigate these functions for a number of basic games, like the connectivity game, the perfect matching game, the clique game and the Hamiltonian cycle game. © 2005 Wiley Periodicals, Inc.
