Also known as Battleship, Mariner, Destroyer and sometimes just Ship.  Sometimes played in bars for drinks.  Five dice are used.

Each player takes it in turn throwing the dice. In each turn a player has three throws of the dice and tries to roll and put to one side a 6 (the ship), a 5 (the captain), and 4 (the mate).  The 6, 5, and 4 may not be rolled out of order so if the first throw contains a 6 and 4, but not a 5, only the 6 is put aside and the rest of the dice, including the 4, are rolled again.  If a player fails to throw the 6, 5, and 4 after their three throws they score nothing.  If after three throws a player has put aside the ship, captain and mate the remaining two dice (the crew) are totalled to form the player's score.  If all three in the sequence are rolled before the third and final throw then the remaining two dice (the crew) are rolled in the remaining turn(s) to improve the total of the player's score.
