Let G be a graph and let k be a positive integer. Consider the following two-person game which is played on G: Alice and Bob alternate turns. A move consists of selecting an unlabeled vertex v of G and assigning it a number a from 0,1,2,...,k satisfying the condition that, for all u∈V(G),u is labeled by the number b previously, if d(u,v)=1, then |a-b|<d, and if d(u,v)=2, then |a-b|<1. Alice wins if all the vertices of G are successfully labeled. Bob wins if an impasse is reached before all vertices in the graph are labeled. The game L(d,1)-labeling number of a graph G is the least k for which Alice has a winning strategy. We use λ1d(G) to denote the game L(d,1)-labeling number of G in the game Alice plays first, and use λ2d(G) to denote the game L(d,1)-labeling number of G in the game Bob plays first. In this paper, we study the game L(d,1)-labeling numbers of graphs. We give formulas for λ1d( ^{Kn}) and λ2d( ^{Kn}), and give formulas for λ1d(Km, _{n}) for those d with d<maxm,n.
