Have each player roll one die. The player who rolls the highest number begins play.
Roll all five dice. The player must keep a 6 before a 5 or 4. If a 6 is rolled, place it to the side. A player may keep one 6, or one 6 and one 5, or one 6, one 5 and one 4. If a player keeps all three, his score is final. He may not roll again.
Roll again. If the player set aside a 6, she will be rolling only four dice. If the player gets a 5, she keeps it with the six. The player may keep a 5 and 4 if she rolled both. If she chooses to do so, she will not roll again.
Roll the remaining three dice. If a 4 turns up, place it with the 5 and 6. Now the player has ship (6), captain (5), and crew (4). Three rolls is the limit. If the player does not have 6, 5 and 4, his score is 0 and it is the next player's roll.
Add the two remaining dice from Step 4 to get the player's score. That sum becomes the point. Every following player rolls in the same manner, trying to beat the point. The player with the highest score after all players roll is the winner.
