Game of the Amazons in 1994, and an updated version with graphics in Visual Basic in 1995. There are Amazons tournaments at the Computer Olympiad, a series of computer-versus-computer competitions. Usually, in the endgame, the board is partitioned into separate "royal chambers", with queens inside each chamber. We define simple Amazons endgames to be endgames where each chamber has at most one queen. Determining who wins in a simple Amazons endgame is NP-hard. This is proved by reducing it to finding the Hamiltonian path of a cubic subgraph of the square grid graph. Generalized Amazons (that is, determining the winner of a game of
