Brax (game)
Brax is a two-player abstract strategy board game. It was invented in 1889 (or shortly before) in America by Frederic B Denham of New York City. The board design is unique. There are several marked paths on the board where a player moves their pieces. A piece can move one or two spaces in a turn depending upon the color of the path. Players attempt to capture each other's pieces.
