Přehled

Celebrated across the Swahili coast as the supreme intellectual contest of the Indian Ocean littoral, Bao la Kiswahili (from the Swahili word bao, meaning "board") stands among the most sophisticated abstract strategy games ever devised. Long rooted in the maritime cultures of the Bajun, the Swahili city-states, Zanzibar, coastal Tanzania and Kenya, and the Comoro Islands, the tradition also reaches inland Muslim commercial hubs, the Sakalava communities of northwestern Madagascar, the Yao of Malawi (who revere it as Bawo), and inland outposts from Kisangani in DR Congo to Bujumbura in Burundi. French colonial chronicler Étienne de Flacourt recorded an early Sakalava variant known as Fifangha as far back as 1658, while English Orientalist Thomas Hyde observed it on Anjouan in 1694. The British Museum preserves the oldest surviving physical specimen—a finely carved Malawian board dating to 1896. Renowned for its demanding multi-lap cascades, shifting tactical tempos, and strict capture imperatives, the game was a lifelong passion of Tanzania’s founding father, Mwalimu Julius Nyerere, as well as Zanzibar’s first president, Abeid Amani Karume.

Deska

• Řady: Four
• Jamky v řadě: Eight
• Sklady: none (seeds are captured from the opponent's front row)
• The holes are rounded except the fourth from the right in the central rows, which is square and called nyumba ("house"). A nyumba ceases temporarily to be a functional nyumba when it has less than six seeds, and ultimately when its contents have been captured or moved in a lap.
• The ultimate holes at either end of the inner rows are called kichwa ("head"); both the ultimate and the penultimate holes are known as kimbi.
• Počáteční pozice: each player has 22 seeds in reserve; seeds are laid out on the board as shown in the diagram:

0 0 0 0 0 0 0 0 0 2 2 6 0 0 0 0 0 0 0 0 6 2 2 0 0 0 0 0 0 0 0 0

Jak hrát

• There is an initial phase with special rules, called namu, in which seeds are introduced into play, and the main stage called mtaji, which starts after the move that put the last seed on the board.
• Bao la Kiswahili is a game with multilap sowing. Each player only sows around his own two rows.
• Moves can be with or without capturing. Non-capturing moves are also known as takata. Captures are mandatory.
• A prerequisite for making a capture is to have at least two occupied holes facing each other in the players' front rows. Any such position results in a capture during the namu stage, but in the mtaji stage the last seed of the first lap must fall into an occupied hole in opposition to really effect a capture. Only the contents of the opponent's front row can be captured; those in his back row are safe.
• General rules:
  • If the first lap of a move doesn't capture, nothing will be captured in the full move. If the first lap captures, multiple captures can follow, even if they are interrupted by non-capturing laps.
  • If 16 or more seeds are sown in the first lap, nothing will be captured. (This rule only applies to the second stage.)

Namu Stage

Non-capturing moves:

• If it is not possible to make a capture, the player takes a seed from his reserve and puts it into a non-empty hole in his front row:
  • If the player has a nyumba, he is not permitted to put the seed into it unless it is the only occupied hole in his front row.
  • If the player has no nyumba, he can only add the seed to a hole which contains at least two seeds, unless all non-empty holes in the front row are singletons.
• After that the player picks all the seeds from this hole and sows them into consecutive holes in either direction (clockwise or anticlockwise).
• If the seed is put into a nyumba, he takes just two seeds from it and sows them in either direction.
• If the last seed is sown into a non-empty hole, but not a nyumba, its contents are taken and the sowing continues until the last seed falls in an empty hole, which also ends the turn.
• If the lap ends in the nyumba, the move is not continued and the turn is over without delay.

Capturing moves:

• After the player has put a seed into a hole which effects a capture, he takes the contents of the opponent's inner hole opposite to it and sows them towards the center of his inner row starting in a kichwa:
  • If he has captured from a kimbi, he must start in the kichwa of the same side (left or right).
  • If he has captured from the four central holes, he may choose the kichwa.
• He continues in laps as in takata unless the last seed is dropped into an occupied hole of his inner row and the opponent's hole opposite is not empty either, which results in another capture:
  • The captured seeds must now be sown towards the center from the kichwa which is in the direction from where he arrived (so that the direction of sowing remains unaltered), unless he captured from a kimbi of the other end of the row; then he starts from the kichwa of this side and the direction of sowing is reversed.
  • If the player ends a lap in his nyumba, he can either choose to stop sowing or he may continue (called safari), which would destroy the nyumba forever.

Mtaji Stage

Non-capturing moves:

• If the player has no reserve seeds left and cannot capture, he may choose any hole of his front row (including the nyumba) which contains more than one seed, and then sow its contents in either direction.
• If there are only singletons in the front row, he may take a hole in his back row, but no singletons. The move keeps on going with multiple laps until the last seed is dropped into an empty hole.
• The front row may never be emptied, not even temporarily. If the only occupied hole of the front row is a kichwa and it contains two or more seeds, they must be sown towards the center of the front row.

Capturing moves:

• A capture can be effected starting from any hole in either row with at least two seeds. The captured seeds are sown in a new lap towards the center from the kichwa which is in the direction from where he came, unless he captured from a kimbi of the other end of the row; then he starts from this side and the direction of sowing is reversed.
• He continues in laps until the last seed falls into an empty hole.
• In contrast to the namu stage, the player must safari (continue to sow) if the sowing ends in the nyumba.

Takasia:

• A special rule of the mtaji stage. If after a takata move the contents of only one opponent's hole are under threat of being captured, but not one of the player's own holes is menaced (that is, the opponent must also takata), this hole is takasiaed. The opponent cannot start his turn from it, nor would a move be continued if a lap ends in it, unless it has been reached in the first lap from a nyumba. A nyumba itself cannot be takasiaed, nor can a hole that is the only occupied one or the only one containing more than one seed in the player's front row.

Zajímání

• Captures are mandatory and only affect the opponent's front row; back-row seeds are safe.
• First-lap capture is required for any capture in a move (with multiple captures allowed afterwards).
• A move that sows 16 or more seeds in its first lap captures nothing (mtaji stage only).

Konec hry a vítězství

The player wins either by "Bao hamna", that is capturing all seeds of the opponent's front row, or by leaving his opponent just singletons, so that he isn't able to move.

Poznámky

• Seed setup ritual: Traditional players quickly verify the 32-stone count per side by filling their pits evenly in preliminary patterns, then clearing the 20 seeds from the outer back rank and two stones from the far-right inner pocket to establish the exact 22-seed reserve alongside the standard opening board.
• Literary and cultural heritage: The game is immortalized in classical Swahili poetry, notably the 1820s composition "Bao Naligwa" by Mombasa bard Muyaka bin Haji al-Ghassaniy, as well as modern reflections like Malawian writer Felix Mnthali's "A Game of Bawo" (1980).
• Institutions and competition: Formal tournament play was invigorated in 1966 with the founding of Tanzania's Chama cha Bao under national patronage. Enthusiasts compete in historic coffeehouses across Stone Town (Zanzibar), coastal Kenyan town squares, Malawian leagues, and international organizations such as the Klubo Internacia de Bao-Amantoj (KIBA) and the Mind Sports Olympiad.
• Related variants: Closely related members of the Swahili-Bao cluster include Bawo (Malawi), Bao la Kete (Lamu Archipelago), and the introductory training ruleset Bao la Kujifunza.
