When he is ready to make a guess he points his wand to where he thinks the balls are--directly in front, if he suspects the balls to be in the two inside hands.

If he thinks the balls are in the two outside hands, he points his wand to one of the hands and extends his empty hand toward the other; in that case the Guesser stands with both of his arms extended.

As soon as the Guesser points with his wand, the hands indicated must be at once opened, palms upward, so that all can see whether the guess is right or wrong.
Every correct guess counts one for the side of the Guesser.

As soon as a correct guess is made, the Judge for that side takes up one of the tally-rods and lays it toward his side; this shows that a point has been won for that side.

If the guess is wrong, the Judge for the other side takes up one of the tally-rods and lays it over on his side.
