Capture not one piece but a whole line, step toward an enemy run or away from it, then chain your sweeps across the board.
Fanorona is played on a board of five rows and nine columns of points joined by lines. Slide a stone one step along a line into an empty point to capture. By approach, you land next to an enemy line and sweep the whole straight run ahead; by withdrawal, you step directly away from an adjacent enemy line and take the run behind. Capturing is compulsory, and a capture may continue as a chain with the same stone as long as each step changes direction and visits fresh points.
Fanorona is the national board game of Madagascar, grown from the older alquerque family and recorded on the island since at least the 17th century. It carries real cultural weight there — it appears in Malagasy oral history, including accounts of priests playing it for guidance during the French siege of the capital.
Its distinctive rule is that you capture by approach or withdrawal: moving a piece toward an enemy line removes it, and so does moving directly away from one. A single move can therefore clear a row you were not even facing, and a capturing sequence may be continued as long as more captures exist, which means one careless opening can unravel half a side. Few traditional games punish a bad first move so immediately.
