The game is played on a initial empty odd-size square board (let's say 9x9).
Another way to define victory is to state that when both players pass, wins the one with more stones on the board.
The first stage has ended, both players had dropped 8 stones into a 9x9 board.
Cell  is valid for both players, cell  is not valid for either player!
Ralf Gering tried the game: It's quite Go-like in the way it feels and influence plays an important role. [...] Wong's Game played on 15x15 needs about 4 Komi for White to balance Black's first move advantage.
