Abstract We investigate Hunters & Rabbit game on graphs, where a set of hunters tries to catch an invisible rabbit that is forced to slide along an edge of a graph at every round. We show that the minimum number of hunters required to win on an (n× m)-grid is⌊ min {n, m} 2⌋+ 1. We also show that the extremal value of this number on n-vertex trees is between Ω (log n/log log n) and O (log n).
