There is no komi; Black is restricted on their first turn to playing no more than two stones. The winner is determined by Chinese scoring: occupied and surrounded points each count 1 point; captured stones do not have point value. The inventor suggests a 15×15 square-celled board using square-tiled pieces. 433:.

He sees it as a game in its own right, not just as a prelude to Go, but also as a way to introduce simple concepts that lead to Go. For the latter purpose, he recommends progressing to "most capture", in which the player capturing the most stones wins. This variation is often called 343: 410:, and differs from standard Go in a number of ways, most noticeably in the way in which certain areas of the board are worth different points values.
