Pente Grammai ("five lines") is an ancient Greek board game described by Roman writers as the most popular game in classical Athens — older than chess by at least a millennium. The exact rules are partially reconstructed from inscriptions and archaeological boards. This implementation follows the most cited reconstruction.
Two players, each with 5 stones, on a board of five horizontal lines. Move stones along lines; capture by flanking. The "sacred line" (middle) is special — stones on it can't be captured but also can't move forward. Whoever captures more stones wins.
Partial. Multiple plausible rule sets exist; the exact rules are debated by historians. This implementation uses the most-cited Sweetser reconstruction.
Far simpler — five stones per side and one type of move. Closer in spirit to draughts (checkers) but with a unique sacred-line mechanic.
Mentioned by Sophocles, Aristophanes, and Plato as the most popular game in 5th-century Athens. Boards have been excavated at the Agora and across the ancient Greek world.
