According to Greek mythology, the Amazons were a race of warrior women within ancient Greek civilization. They originated from the area around the Caucasus Range and settled in Asia Minor on the shores of the Black Sea. Women entirely ruled their society, and two queens, one for defense and one for domestic affairs, shared the sovereign rule. Amazons is a two-player board game invented in 1988 by Walter Zamkauskas of Argentina. El Juego de las Amazonas (The Game of the Amazons) is a trademark of Ediciones de Mente. It can be played on boards of arbitrary n x n size, however, it is usually played on a 10 x 10 board.

Please try the program and send comments, suggestions, observations, bug reports, spectacular wins, etc. to lorentz@csun.edu. I am currently seeking students interested in doing masters projects in this area. Invader is currently the top Amazons playing programs in the world and so this is an opportunity to be involved in an exciting and current project. Perhaps with your help we can keep our title a little longer.
