Sungka is played on a long wooden board carved to resemble a boat, with fourteen small holes and two large stores called "bahay" (houses). Cowrie shells are the traditional playing pieces. It belongs to the same broad sowing family as Congklak and Ayo.
Variant implemented
Philippine Sungka, 2×7 pits with 7 shells each, simultaneous-free sequential opening, multi-lap sowing, capture with "sunog" (burnt) pits skipped.
Board and pieces
A long boat-shaped wooden board with fourteen small holes and two large stores called "bahay" (houses). Cowrie shells are the traditional pieces.
Setup
Seven shells in each of the fourteen small holes.
Turn
Scoop up a hole on your own side and sow anticlockwise, one shell per hole, including your own house but never your opponent's. If the last shell falls into an occupied hole, pick that hole up and keep going.
Capture and scoring
A final shell landing in an empty hole on your own side captures that shell plus everything in the hole opposite.
Win condition
When one side is emptied the other player takes the remainder. Most shells wins.
Draw condition
Equal counts are a draw.
Special rules
Ending in your own house grants another turn. In face-to-face play both players open simultaneously; that opening race is not modelled here — play alternates from the first move.
Computer opponent
Same alpha-beta engine as Congklak, tuned for the identical board geometry.
