Southeast Asian mancala

Southeast Asian mancalas are a subtype of mancala games predominantly found in Southeast Asia. They are known as congklak (VOS Spelling: tjongklak), congkak, congka, and dakon in Indonesia, congkak in Malaysia and Brunei, and sungkâ in the Philippines. They differ from other mancala games in that the player's store is included in the placing of the seeds. Like other mancalas, they vary widely in terms of the rules and number of holes used.
Names.
Southeast Asian mancalas are generally known by variations of similar cognates which are likely onomatopoeiac. The names have also come to mean the cowrie shells, predominantly used as the seeds of the game. These names include (VOS Spelling: "tjongklak"; also spelled as "tsjongklak" in Dutch sources), , , , and in Indonesia, "congkak" in Malaysia and Brunei, and "sungkâ" (also spelled "chonca" or "chongca" by Spanish sources) in the Philippines.
Historical records show that similar games also existed in Sri Lanka (where it is known as "chonka") and India. In Tamilnadu, India, it is known as Pallanguzhi. A similar game is still found in the Maldives, where it is known as "ohlvalhu" (where "valhu" means "eight", so literally "eight holes"). It has also spread to the Marianas (where it is known as "chongka") and Taiwan via relatively recent Filipino migrations.
Other names for the game include "dakon" or "dhakon" (Javanese), "kunggit" (Philippines), "dentuman lamban" (Lampung), "mokaotan", "maggaleceng", "aggalacang" or "nogarata" (Sulawesi), and "naranj" (Maldives). pallankuzhi (India Tamilnadu)
History.
The oldest mancala game boards were found in a ruined fort of Roman Egypt and date back to the 4th century AD. The original route of dispersal of mancalas into Southeast Asia is unknown. It may have originally entered Southeast Asia via Austronesian trading routes with South Asia.
Indonesia has the largest variation of Southeast Asian mancalas and thus may be likely to be at least one of the major entry points, though this may also be just an artifact of the country's size. Where the characteristic Southeast Asian ruleset originates from is still unknown.
Description.
Southeast Asian mancalas are played by two people on carved wooden elongated boat-shaped boards with cup-shaped holes. Most variants have two sets of seven holes for each player, plus two larger holes at each end which are known as the "stores" of the players. However, the number of holes can vary, ranging from three to nine or more (excluding the stores), and these variants (which can also differ in the rules) can coexist in one area. 
Mancala games are played with "seeds" or "counters", which are usually made from small cowrie shells, pebbles, or tamarind seeds. The holes in Southeast Asian mancalas are typically deeper and larger than variants in mainland Asia and Africa, since the seeds used are larger. A total of 98 pieces are used in the seven-hole board version.
In Indonesia, the holes are called "anak" ("child"), while the larger store holes are called "indung" ("mother"). In the Philippines, the holes are called "bahay" or "balay" ("house"), while the store hole is called "ulo" ("head").
Rules.
The rules for the most common seven-hole mancala versions in Brunei, Indonesia, Malaysia, the Maldives, Marianas, and the Philippines are pretty much identical. Each player controls the seven holes on the side of the board to their left, and their score is the number of seeds in their store holes. Seven seeds are placed in each small hole except for the players' store hole. The objective of the game is to capture more seeds in the store than one's opponent.
Both players begin simultaneously by scooping up all the seeds in any hole on their side. Each drops a seed into the next hole and continues clockwise depositing one seed into every hole thereafter. A player drops a seed into his store each time he passes it but does not deposit any into his opponent's store.
How the game continues, depends on where the last seed of each scoop is deposited.
The first round ends when a player has no more seeds in his holes. The remaining seeds are awarded to his opponent.
Play resumes in the second round with players redistributing seeds from their own store to their own holes. Beginning from left to right, seven seeds are placed in each hole. If a player does not have sufficient seeds to fill his own holes, the remaining holes are left empty and are considered 'burnt'. The leftover seeds are deposited into his own store. The opponent deposits excess seeds he has won into his own store.
The loser gets to start the second round. Play is continued as before but players will bypass 'burnt' holes and no seeds are to be dropped into these holes. If a seed is accidentally dropped into a 'burnt' holes, it is confiscated and stored in the opponent's store.
Play continues until one player loses all his holes or concedes defeat.
Cultural significance.
The game is regarded as useful for developing certain mathematical principles.
The second series Malaysian Ringgit 10 sen coin has a Congkak board on the reverse in recognition of the long history of congkak in Malaysia.
Dakon stones.
In Java, the term "dakon stone" refers to the similarly pitmarked stones from the bronze-iron age period of Indonesia. These stones have rows of 4 or 5 cup-shaped holes (called "cupules" in archaeology) and two holes at each end, a formation which has much in common with that of "congklak". This prehistoric dakon stones is unrelated to the game and were probably employed in ceremonies to propitiate ancestors. Such stones can be found around Java.
Similar cup-shaped depressions are also found in other Austronesian cultures, most notably in Polynesia.
