Abstract

We prove that for each D2D\ge 2 there exists c>0c>0 such that whenever bc(nlogn)1/Db\le c\big(\tfrac{n}{\log n}\big)^{1/D}, in the (1:b)(1:b) Maker-Breaker game played on E(Kn)E(K_n), Maker has a strategy to guarantee claiming a graph GG containing copies of all graphs HH with v(H)nv(H)\le n and Δ(H)D\Delta(H)\le D. We show further that the graph GG guaranteed by this strategy also contains copies of any graph HH with bounded maximum degree and degeneracy at most D12\tfrac{D-1}{2}. This lower bound on the threshold bias is sharp up to the log\log-factor when HH consists of n3\tfrac{n}{3} vertex-disjoint triangles or n4\tfrac{n}{4} vertex-disjoint K4K_4-copies.
