Abstract

Domineering is a well-studied tiling game, in which one player places vertical dominoes, and a second places horizontal dominoes, alternating turns until someone cannot place on their turn. Previous research has found game outcomes and values for certain rectangular boards under normal play (last move wins); however, nothing has been published about domineering under misère play (last move loses). We find optimal-play outcomes for all 2 × n boards under misère play: these games are Right-win for n ⩾ 12. We also present algebraic results including sums, inverses, and comparisons in misère domineering.
