Rules
Following are the rules for the abapa variation, considered to be the most appropriate for serious, adult play.Equipment
The game requires an oware board and 48 seeds. A typical oware board has two straight rows of six pits, called "houses", and optionally one large "score" house at either end. Each player controls the six houses on their side of the board, and the score house on their end. The game begins with four seeds in each of the twelve smaller houses.Boards may be elaborately carved or simple and functional; they may include a pedestal, or be hinged to fold lengthwise or crosswise and latch for portability and storage with the seeds inside. While most commonly located at either end, scoring houses may be placed elsewhere, and the rows need not be straight. When a board has a hinged cover like a diptych

, the scoring houses may be carved into the two halves of the cover, and so be in front of the players during play. The ground may also be used as a board; players simply scoop two rows of pits out of the earth.

Object
The object of the game is to capture more seeds than one's opponent. Since the game has only 48 seeds, capturing 25 is sufficient to accomplish this. Since there is an even number of seeds, it is possible for the game to end in a draw, where each player has captured 24.Sowing
Players take turns moving the seeds. On a turn, a player chooses one of the six houses under their control. The player removes all seeds from that house, and distributes them, dropping one in each house counter-clockwise from this house, in a process called sowing. Seeds are not distributed into the end scoring houses, nor into the house drawn from. That is, the starting house is left empty; if it contained 12 seeds, it is skipped, and the twelfth seed is placed in the next house. The diagram shows the result of sowing from house E.Knowing the number of seeds in each house is, of course, important to game play. When there are many seeds in a house, sometimes enough to make a full lap of the board or more, they cannot easily be counted by eye, and their number is often guarded by the player who controls that house. This may be done by repeatedly moving the seeds in the house. A player may count the seeds when contemplating a move; in such cases the last few are usually counted in the hand to avoid revealing their number.
Capturing
After a turn, if the last seed placed into an opponent's house brought the house's total to exactly two or three, all the seeds in that house are captured and placed in the player's scoring house (or set aside if the board has no scoring houses). If the previous-to-last seed also brought an opponent's house to two or three, these are captured as well, and so on. Therefore, seeds may be captured from every consecutive house on the opponent's side whose seed total was brought to two or three on the player's current turn. However, if a move would capture all an opponent's seeds, the capture is forfeited, and the seeds are instead left on the board, since this would prevent the opponent from continuing the game. In the diagram to the right, the lower player would capture all the seeds in houses c, d, and e but not a, since it is not contiguous to the other captured houses.Let the opponent play
The proscription against capturing all an opponent's seeds is related to a more general idea, that one ought to make a move that allows the opponent to continue playing. If an opponent's houses are all empty, the current player must make a move that gives the opponent seeds. If no such move is possible, the current player captures all seeds in his/her own territory, ending the game.Winning
The game is over when one player has captured 25 or more seeds, or each player has taken 24 seeds (draw). If both players agree that the game has been reduced to an endless cycle, each player captures the seeds on their side of the board."Grand Slam" variations
A grand slam is when you capture all of your opponent's seeds in one turn. There are variations to the rule that applies, which may be one of the following:- Grand Slam captures are not legal moves.
- Such a move is legal, but no capture results. International competitions often follow this rule.
- Grand Slam captures are allowed, however, all remaining stones on the board are awarded to the opponent.
- Such a move is legal, but the last (or first) house is not captured.
Various other rules also exist.
History and society
Oware is perhaps the most widespread game in the mancala family of games.Reflecting traditional African values, players of oware encourage participation by onlookers, making it perhaps the most social two-player abstract. In recreational play, it is normal for spectators to discuss the game in progress and to advise the players. Games may provide a focus for entertainment and meeting others. The game, or variations of it, also had an important role in teaching arithmetic
