A game played on a cross-shaped board with 33 holes. All holes but the middle one are initially filled with pegs. The goal is
to remove all pegs but one by jumping pegs from one side of an occupied peg hole to an empty space, removing the peg which was
jumped over. Strategies and symmetries are discussed in Beeler *et al. *(1972, Item 75). A triangular version called Hi-Q
also exists (Beeler *et al. *1972, Item 76). Kraitchik (1942) considers a board with one additional hole placed at the vertices
of the central right angles.
