In 1978, John Hunter created the World Peace Game to teach his Virginia high school students about creativity, problem solving, and peace. Then, the homemade game was a 4-by-5-foot piece of plywood featuring the outlines of countries; students assumed roles as global leaders and were tasked with finding solutions to some of the world’s most complex problems. Today, the game is a 4-foot-square, four-layer Plexiglas structure, and Hunter’s fourth-grade players must successfully solve 50 interlocking problems—while increasing the asset value of each country—to win.
