Chowka Bara or Ashta Chamma is a two- or four-player board game from India. This game is an example of a “fully observable” system that has an element of chance introduced by the roll of special dice and an element of strategy. While traditionally played with 4 or 6 cowry shells, dice can also be used.

Cowrie or cowry (pl. cowries) is the common name for a group of small to large sea snails, marine gastropod mollusks in the family Cypraeidae, the cowries.
