The full game is played on a 19 x 19 board, needing a total of over 300 black and white pieces. Beginners, however, often play on a 9×9 board, and you can create this by building a 4×4 grid with the tiles and placing pieces on the points.

The intricacies of this game are not easily covered in a short blog post, so we will limit ourselves to directing you over to Wikipedia to get started.
