This is the Enigma, the classic Battleship game turned into a simple to play (and fun) bar game.
It´s played just like the usual Battleship game with one addition. If you miss the target you drink a sip of water, and if you hit an enemy boat your opponent empties the corresponding shot glass.
The exterior design of the wood case was based on the enigma encrypting machine as well as the game´s name. The game also features a radar screen to mark the shots of each player and a list of the ships remaining.
Have fun, and drink responsibly!
