SSC Virtual Sports Museum - Traditional Sports Congkak is a game for two players using a board which has several storehouses. The aim of the game is to gather as many shells into the storehouses on the player's side. Normally, either cowrie shells or tamarind seeds are used.
Players sit facing each other.
Both players begin simultaneously by scooping up all the shells in any house on their side. Each drops a shell into the next 'house' and continues clockwise depositing one shell into every house thereafter. A player drops a shell into his 'storehouse' each time he passes it but does not deposit any into his opponent's 'storehouse'. How the game continues, depends on where the last shell of each scoop is deposited. The player scoops up all the shells in that 'house' and continues distributing them as described above.
