Kalah, also called Kalaha or Mancala, is a game in the mancala family invented by William Julius Champion Jr (USA) in 1940. This game heavily favors the starting player, who will always win the three-seed to six-seed versions with perfect play. This game is sometimes also called "Kalahari", possibly by false etymology from the Kalahari desert in Namibia.

As the most popular and commercially available variant of mancala in the West, Kalah is also sometimes referred to as Warri or Awari, although those names more properly refer to the game Oware.

An electronic version of the game, called Bantumi, was included on the Nokia 3310. The handset went on to sell 126 million units making Bantumi the best selling version of the game.

Equipment

The game requires a Kalah board and 36 seeds or counters. The board has six small pits, called houses, on each side; and a big pit, called a Kalah or store, at each end. Many games sold commercially come with 48 seeds or counters, and the game is started with four seeds in each house.

Object

The object of the game is to capture more seeds than one's opponent.

Example turn

The player begins sowing from the highlighted house.

The last seed falls in the store, so the player receives an extra move.

The last seed falls in an empty house on the player's side. The player collects the seeds from both his house and the opposite house of his opponent and moves them to his store. The player's turn ends.

Rules

  1. At the beginning of the game, three seeds are placed in each house.
  2. Each player controls the six houses and their seeds on the player's side of the board. The player's score is the number of seeds in the store to their right.
  3. Players take turns sowing their seeds. On a turn, the player removes all seeds from one of the houses under their control. Moving counter-clockwise, the player drops one seed in each house in turn, including the player's own store but not their opponent's.
  4. If the last sown seed lands in the player's store, the player gets an additional move. There is no limit on the number of moves a player can make in their turn.
  5. If the last sown seed lands in an empty house owned by the player, and the opposite house contains seeds, both the last seed and the opposite seeds are captured and placed into the player's store.
  6. When one player no longer has any seeds in any of their houses, the game ends. The other player moves all remaining seeds to their store, and the player with the most seeds in their store wins.

It is possible for the game to end in a draw, with 18 seeds each.
