Ohvalhu ("game of eight (holes)"), also known as Ohvalhu gondi, is a mancala game played on the Maldives. It is closely related to the Indonesian games of Congkak and Dakon, although it is not identical with either of them as has been erroneously stated by Alexander Johan de Voogt. Two Maldive game boards of the Museum of Archaeology and Paleontology, University of Pennsylvania, were depicted by Stewart Culin for playing the game of Naranj, probably the same game as Ohvalhu, in 1894.
The game has been solved by human players and it is a win for the first player in the first move.
The rules are similar to Congkak except for the following differences:
- Ohvalhu is played on a board with two rows, each one with six, seven, eight or ten holes. Eight is considered standard. At both end there are also large stores, each player owning the one to his right.
- Each hole contains eight cowrie shells, if a standard board is used, otherwise the number of shells is adjusted to the number of holes in the row.
- The opening is played in turns. There is no simultaneous opening move.
The game is usually played in rounds:
After a game has ended, the players fill their holes from the left to the right with their winnings, putting into each hole the original number of shells. Those holes, which cannot be filled are marked with a leaf and are skipped in the next round. The remaining shells are put into the player's store. The game is over when a player has not enough shells to fill even one hole.
