Overview
Rio Kadalis (also transcribed Riya ka dhalis or Riyo-ka-dhalis, literally meaning "helping a nanny goat give birth") is a traditional two-row mancala game played across Somalia, prominently among the Habr Awal and allied clans in Hargeisa and the Jigjiga region. First systematically documented in 1971 by Ethiopianist historian Richard Pankhurst, the game is intimately linked to the livestock traditions of Somali pastoralists. It is closely related to Horn of Africa mancala variants documented across Eritrea and Ethiopia, such as Lahemay Waladat, Lam Waladach, and Lamosh.
Board
- Ranks/rows: Two
- Holes per row: 6 (a five-hole layout is also traditionally utilized among some Habr Awal players)
- Stores: None (captured stones are held off the board)
- Seeds per hole at start: 4 (total seeds: 48 on a standard six-hole board)
- Holes are typically scooped into sand or earth, or carved into flat limestone outcroppings.
How to Play
- Players alternate turns. On their turn, a player lifts all stones from one of their holes and sows them, one by one, counter-clockwise (anti-clockwise) into subsequent holes (some Somali communities play clockwise).
- Sowing proceeds via multi-lap relay: if the last stone lands in an occupied hole, its entire contents are scooped up and distributed in another lap.
- A move concludes when the last stone drops into an empty hole, or when it creates a group of four stones—a situation termed in Somali as binikh ("wasting").
Capturing
- Any group of four formed at any point during a sowing lap belongs to the owner of the row in which it forms.
- Binikh exception: A group of four formed specifically by the last stone of a lap (binikh) is captured by the player currently moving, regardless of row ownership.
End of Game and Winning
- The game terminates when a player is unable to make a legal move on their turn (immobilization).
- Any stones remaining in the holes when the game ends are claimed by the player on whose side of the board they reside.
- The player who has won the greater number of four-stone groups wins the round.
- Match play: Following a round, each player refills their holes with four stones each from their accumulated winnings. Any holes that cannot be filled with four stones are closed with sand for that round, but may be reopened in subsequent rounds if enough stones are recaptured. The ultimate objective of a match is to close all of the opponent's holes, reducing their pieces to fewer than four.
Notes
- The game's evocative name reflects the pastoralist culture of Somali nomads, comparing the careful gathering and extraction of four-stone groupings to the birth of a newborn goat kid.
- The term binikh signifies "wasting" or "spoiling," describing the way an opponent's pit is raided by the mover's final stone.
