Kauda, a game played with 16 sea shells, adds an extra flavor to the festive moods of Tihar for merrymakers if it is played in good spirit; otherwise, it can turn out to be a bitter experience. Strictly speaking, Kauda is illegal gambling in Nepal, but its aficionados often manage to play the game right under the nose of law enforcers.
According to the law, any game that involves loss or gain of money is called gambling. In this sense, even playing cards is illegal, but drinking and gambling are common during the Festival of Lights that is Tihar.
Kauda can be played with a little money in a friendly atmosphere but it generally involves large stakes. Sometimes the game ends when a single player wins all the money while others have nothing left with them to bet. Yet that does not deter the defeated enthusiasts from playing the game again with hope of making fortune the next time.
The origin of the game is unknown but is said to be a part of the Hindu culture. Unlike the dice game – mentioned in the Mahabharata – which is popular in India, Kauda thrives in Nepal and is a unique feature of our culture.
The game is played with four players sitting in four directions, facing each other who throw the shells to test their fortune. The four players get four seats called ‘khal’ or ‘dau’ respectively which are named as teeya (three), chauka (four), panja (five) and chakka (six).
When a player representing a particular dau throws the 16 shells, there is an outcome of 17 possible combinations depending on the position of the grooves of the shells. Out of the 17 results, five goes to chauka dau, the rest of the players get four each. If the player gets his designated result, he wins all the money that lies on the ground. If the result goes to some other dau, the thrower of the shells has to pay.
For instance, if the grooves of four shells face upwards and the rest face down, the result goes in the favor of the chauka dau. If five shells face upwards, then panja will win the bet. This goes on in a cyclic order until all the daus get their chance.
The chances of all the shells facing up or all facing down are very rare, and they represent the chauka dau. Therefore, chauka gets five chances while others get four.
Besides the players, unlimited number of people called Chyakhes also can bet money in the game on behalf of the four players. The player however reserves the rights to allow people to bet money. This ensures that both the parties are ready either to gain money or lose their fortune.
Chyakhes can bet their money anywhere they like except for the one who tosses the shells. That means there are three seats out of four where they can bet their money. If the shells show the seat where the money is placed, the money gets doubled. However, if the shells show the results in favor of the thrower, he collects all the money.
The most exciting part of the game is the Mar-taal, when a player wins a few consecutive bets. The losers double their original bets each time they lose. Thus the thrower of the shells collects money from the other three players; but in the end, he has to pay only to one player, although the amount he pays is multiplied by the number of times he has won.
