Krig is a varient of Game of the Generals. The game simulates armies at war trying to overpower, misinform, outflank, outmaneuver, and destroy each other. It optimizes the use of logic, memory, and spatial skills. It simulates the "fog of war" because the identities of the opposing pieces are hidden from each player and can only be guessed at by their location, movements, or from the results of challenges. The game allows only one side's plan to succeed, although a player may change plans during the course of the game. In addition, there are two different ways of winning the game. Certain strategies and tactics, however, allow both sides the chance of securing a better idea of the other's plan as the game progresses.
