We analyze the game of Tchuka Ruma, a solitaire version of the Mancala family. Although the original game begins with 4 pits and 2 stones in each pit, we look at variations with any number of pits and stones per pit. We show that certain configurations are unwinnable, and these account for all of the forced losses that extensive computer calculation is able to find, except for certain "sporadic" examples that occur with only 2 pits. We investigate the cultural origins of the game, and related games, including the contexts in which the game was played. Evidence is presented that, while not conclusive, indicates that the game has a Malaysian or Indonesian origin.
