Tukvnanawopi
Tûkvnanawöpi is a two-player abstract strategy board game played by the Hopi native American Indians of Arizona, United States. The game was traditionally played on a slab of stone, and the board pattern etched on it. Tukvnanawopi resembles draughts and Alquerque. Each player attempts to capture each other's pieces by hopping over them. It is unknown how old the game is; however, the game was published as early as 1907 in Stewart Culin's book "Games of the North American Indians Volume 2: Games of Skill".
