This game is played on the following 13x13 square board. The middle stone is called the neutral stone.
White's turn. After the last drop (the marked white stone) the neutral stone moved from i9 to i8 and White wins by stalemate. Black's j7,i6 or h7 would imply a move of more than one cell, which is invalid.
White dropped the marked white stone. Now, Black can only drop at d11 or d12, pushing the neutral stone to d9. Then White wins by dropping at f9 moving the neutral stone 3 cells into the left edge
Cameron Browne noticed that: This is a type of constrained connection game: as well as propelling the neutral piece, [...] (each move makes) a virtually connected wall that blocks off one of my edges. The pieces will eventually form a maze that we have to navigate around.
This is a variant of Iqishiqi.
