## Abstract

For k ≥ 2 we define a class of graphs Hk = {G: every block of G has at most k vertices}. The class Hk contains among other graphs forests, Husimi trees, line graphs of forests, cactus graphs. We consider the colouring game and the generalized colouring game on graphs from Hk.

Keywords: colouring game, generalized colouring game.
