Have Fun
The first player guesses where the opponents ship is. If they are wrong the person who guessed has to drink, if they were right and they have a hit, the other player has to drink.
You do this throughout the whole game (rarely putting down your beer). When you sink a persons ship they have to drink double of what you sunk. Therefore if you sunk their 5 ship they have to drink 10 drinks. By the time your finished you aint gonna even be able to say “you sunk my battleship”.
