He's sent you a letter to turn round your head.
When the players arrive at that part of the song, "Oh, Mary!" they name some member of the company; when the song is finished, the one named must turn right round and face the outside of the ring, having her back to all the other players. She then joins hands in this position and the game continues as before until all the players face outward. They then recommence, until they all face the inside of the ring as at first.
Fives and Threes
This is another game that is played with dominoes, and is one of the most popular. It is excellent practice for counting, and to be successful at it depends, in a very great measure, upon skill in doing this. Two, three or four players may take part in this game. After the dominoes have been shuffled, face downward, each player takes an equal number of stones, leaving always three, at least, upon the table; no player, however, may take more than seven, and it is perhaps better to limit the number to five.
In playing dominoes, it should always be borne in mind that one end of the domino to be played must always agree in number with the end of the domino it is to be placed against.
The object of the game is to make as many "fives" and "threes" as are possible; for instance, a player should always make the domino show fifteen if he can, as three divides into fifteen five times, and five divides into fifteen three times, and he would thus score 8 (three and five). The way to count is to add the two extreme ends together, always, of course, trying to make the number as high as possible, and to make it one into which either three or five will divide, as if a number be formed into which these numbers will not divide, no score will result.
Suppose there are two players, A and B. A starts the game by playing the double-six, for which he scores 4 (three dividing into twelve four times). B then plays the six-three, making fifteen, and thus scores 8 (the highest score possible, as explained above). A next plays the double-three, which makes eighteen, and scores 6 (three dividing into eighteen six times). B then plays six-blank onto the double-six on the left-hand side and scores 2 (three dividing into six twice). A holding the blank-three, places it onto the blank end, making the number nine, and scores 3. B next plays the three-four, which makes ten, and 2 is added to his score (five dividing into ten twice). Thus the game proceeds, each player trying to make as many fives and threes as possible.
