Chessboard
Board games have been known since ancient history, with the oldest records being paintings in mastabas of the First and Third Dynasties of Egypt (3100-2700 BC). The first known version of chess appeared around the 6th century in India and was called Chaturanga, played on a board of the game Ashtapada. This board was monochromatic and divided into eight columns by eight rows, with special marks called "castles" in the first, fourth, fifth, and eighth squares of the "a", "d", "e", and "h" columns, which served a function in Ashtapada, but not in Chaturanga.
Tsoro
Tsoro is an ancient two-player mathematical strategy board game that has been played for over a thousand years. It has its roots in Zimbabwe and was first described in literature by J. B. Matthews in 1964. Tsoro belongs to the same class of African strategy board games collectively called Mancala, such as Oware, Bao, and Kalah.
