Blue Marble Game (부루마불게임) is a Korean board game similar to Monopoly manufactured by Si-Yat-Sa. While Monopoly is traditionally played across locations in a single city, the Blue Marble Game features cities from across the world; its title is a reference to the "blue marble" description of the Earth as seen from space. The game was first published in 1982. It can be played by 2 to 4 players.
