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.
The only difference is that in Tuknanavuhpi lines of intersection points become unplayable as opposed to rows or columns of squares in Tukvnanawopi when the game progresses.
Another similar game is played by the Keres native American tribe in New Mexico called Aiyawatstani.
Each player's 20 pieces are set up on their half of the board on the intersection points including the middle (5th.)
On a player's turn, a piece may be moved in any direction along a line onto an adjacent intersection point that is vacant.
As the game progresses, another row or column of squares on one end of the board will eventually become empty, and therefore unplayable.
