Kalah

Kalah is a modern variation in the ancient Mancala family of games. The Kalah board was first patented and sold in the United States by William Julius Champion, Jr. in the 1950s. This game is sometimes also called "Kalahari", possibly by false etymology from the Kalahari Desert in Namibia.

For most of its variations, Kalah is a solved game with a first-player win if both players play perfect games. The pie rule can be used to balance the first-player's advantage.
