An influence map is a way of determining how much one square or tile in a game affects or in- fluences the others. In this column we use in- fluence maps to produce and grade variations of the popular board game Risk, originally published by Parker Brothers. In our variation two giant monoliths appear on the game map that permit troops to pass between them. The influence map is used to determine how much a given placement of the monoliths changes the game.
