USS Lox

During the second world war, submarines came into their own as instruments of war. In the Pacific theater, US submarines disrupted Japanese shipping of supplies, material and personnel. Unlike the German wolf pack strategy, US submarine captains usually operated independently. As the captain of the USS Lox, a (fictional) Salmon-class boat, you are responsible for 58 officers and enlisted submariners. Your mission is to disrupt Japanese war operations by sinking as much shipping as possible.

USS Lox is a solitaire card game that uses a standard deck of cards to model a US submarine patrol in the Pacific during WWII. It borrows from the rules of cribbage.
