How do you play shanuco?

Shanuco is a traditional board game played on a grid, typically 7x7 or 9x9, where players take turns placing pieces on the board. The objective is to form a continuous line of pieces, either horizontally, vertically, or diagonally, while blocking the opponent from doing the same. Players score points by creating connections and must strategize to outmaneuver their opponent. The game continues until all spaces are filled or a player achieves the winning line.
