achi
History
Achi is one of the many traditional Morris-type games that involve placing pieces on a board with the objective of forming a three-in-a-row. The game originated in Ghana where it is often played by children who use pebbles as pieces. In England, game pieces were found near Hadrian's Wall in northern England dating back to the 3rd or 4th century AD.
The Board
The game is played on a board with nine intersection points and lines indicating how pieces can travel among these points.
The Pieces
The first player has three white pieces. The second player has three black pieces.
Rules
To win: Arrange your pieces in a vertical, horizontal, or diagonal line of three.
