Igisoro is a two player game in the mancala family. This variant is played primarily by the Tutsi (also known as Abatutsi or Batutsi) in Rwanda, Burundi and Uganda. Igisoro, like Omweso, is played with an 4×8 board (igisoro) of pits (icúba) and 64 seeds. A player's territory is the two rows of pits closest to them. According to Alexandre Kimenyi, California State University at Sacramento, cow vocabulary is metaphorically used in Igisoro: players try to capture each other's "cows" (inká) and a board position with many singletons are known as "a line of calves" (urunyána).
