The basketball starts in the middle. The highlighted squares are where it may go next: a short step to an adjacent square, or a longer pass further out. An ✕ marks a square already used, closed off for the rest of the game. The dots in front of each goal are the only squares that can score on next move. The board wraps around on itself, left to right (like in Pac-Man). Player 1 scores at the top right, Player 2 at the bottom left. With nowhere legal to go, the game is a draw.
