Abstract

The Maker-Breaker connectivity game and Hamilton cycle game belong to the best studied games in positional games theory, including results on biased games, games on random graphs and fast winning strategies. Recently, the Connector-Breaker game variant, in which Connector has to claim edges such that her graph stays connected throughout the game, as well as the Walker-Breaker game variant, in which Walker has to claim her edges according to a walk, have received growing attention. For instance, London and Pluh\'ar studied the threshold bias for the Connector-Breaker connectivity game on a complete graph KnK_n, and showed that there is a big difference between the cases when Maker's bias equals 11 or 22. Moreover, a recent result by the first and third author as well as Kirsch shows that the threshold probability pp for the (2:2)(2:2) Connector-Breaker connectivity game on a random graph GGn,pG\sim G_{n,p} is of order n2/3+o(1)n^{-2/3+o(1)}. We extent this result further to Walker-Breaker games and prove that this probability is also enough for Walker to create a Hamilton cycle.
