Survista

Bao Kigogo is an expansive four-row mancala played by the Gogo (Wagogo) people across the central plateau of Tanzania's Dodoma Region. The game was first recorded in 1911 by German Lutheran missionary Martin Klamroth, who observed matches in the settlement of Mpapua (modern Mpwapwa) and documented its rules in Archiv für Anthropologie. Structurally related to Bao Kiarabu (the coastal Swahili name for Hawalis), Bao Kigogo unfolds on a generous 4×12 grid. It combines continuous counterclockwise multi-lap relay sowing with an asymmetric opening configuration, requiring players to engineer deep tactical cascades that terminate in empty front-row pockets to strip opponent files.

Tavla

• Rangs/retschas: Four
• Fossas per retscha: Twelve (48 holes total)
• Magazins: None (captured stones are removed permanently from play)
• Each player controls the two ranks on their side of the board.
• Disposiziun iniziala:** Two seeds in every hole except the opposing end holes of the inner rows, which start empty (92 seeds total):

    2 2 2 2 2 2 2 2 2 2 2 2
    2 2 2 2 2 2 2 2 2 2 2 0
    0 2 2 2 2 2 2 2 2 2 2 2

Co giugar

• Players take turns moving stones.
• A player picks up all stones from any hole on their side containing at least two seeds and sows them counterclockwise, dropping one stone per hole around their two ranks.
• Seminada cun stafetta: If the last stone of a lap falls into an occupied hole, all its contents (including the newly dropped stone) are scooped up and sown in a new lap starting in the very next hole.
• Fin dal turn: The turn ends when the last stone drops into an empty hole.
• Quadrels singuls: Single stones may only be moved if the player possesses no holes with two or more seeds. A singleton may only step into the adjacent hole if that hole is currently empty.

Captura

• When the final stone of a move lands in an empty hole in the player's front row, and the directly opposite inner-row hole of the opponent is occupied, all stones in that opponent front-row hole are captured and removed from play.
• If the opponent's back-row hole in that same column is also occupied, its stones are seized as well, effecting a full file capture.
• Stones in the opponent's back row are safe unless the facing front-row hole is captured in the same stroke.

Fin dal gieu e victoria

• A player wins when they successfully capture all stones belonging to their opponent, or leave the opponent immobilized with no legal moves.
• The game is drawn if a board position repeats (cycle).

Notas

• Avertura asimetrica: Leaving the opposite corners of the front rows empty (Row 1 column 11 and Row 2 column 0) prevents opening symmetry and immediately sparks contest over the central files.
• Liaischs interculturals: Closely affiliated with Bao Kiarabu (Hawalis), Njombwa (Mozambique), and related southern and eastern African four-row relay games.
• Documentaziun istorica: Martin Klamroth, Afrikanische Brettspiele, in Archiv für Anthropologie (1911).
