Abstract

Motivated by the burning and cooling processes, the burning game is introduced. The game is played on a graph GG by the two players (Burner and Staller) that take turns selecting vertices of GG to burn; as in the burning process, burning vertices spread fire to unburned neighbors. Burner aims to burn all vertices of GG as quickly as possible, while Staller wants the process to last as long as possible. If both players play optimally, then the number of time steps needed to burn the whole graph GG is the game burning number bg(G)b_g(G) if Burner makes the first move, and the Staller-start game burning number bg(G)b_g'(G) if Staller starts. In this paper, basic bounds on bg(G)b_g(G) are given and Continuation Principle is established. Graphs with small game burning numbers are characterized and Nordhaus-Gaddum type results are obtained. An analogue of the burning number conjecture for the burning game is considered and graph products are studied.
