93 Sqn Linebook No. 2 - Page 47 The instructions for 7-14-21 are as follows: 1. The minimum number of players is 4.   There is no maximum, but the ideal number is between 4 and 7 players.   2. Put 5 dice into a cup, and hand them to the first player.   3. Roll the dice, and remove any dice that have a number 1 on them.   Keep track on a scrap piece of paper how many ones have shown up.   If the roller rolls any ones, they get to keep rolling.   If the roller fails to roll a one, he/she passes the dice to the next player and that player starts rolling 5 dice again.   4. Roll the seventh number one at the table.   This means that player gets to name the shot that will be consumed later in the game.   (Note the lethal shot listed above).   5. Roll the fourteenth one at the table.   This means that player must now purchase the shot that was named by the player earlier in the game.   6. Roll the twenty-first one at the table.   This means that player must drink the shot.   It doesn't matter if he/she likes the shot that has been called.   It's actually better if the player drinking doesn't like it, it adds to the penalty he/she is suffering for rolling the twenty-first one at the table.   7. Start the game over with a new tally of ones rolled at the table, repeating Steps 2 through 6 as many times as the players at the table wish to play the game.   (Thanks to RAF Museum and Alan Kirk, eHow Contributor for the rules.)
