A Korean knock-off of Monopoly. Instead of buying streets, you're buying land in cities (Seoul replaces Boardwalk), where you have the option of buying different buildings. Community Chest and Chance cards are conflated into one "Key" card that gives you either some sort of bonus or a penalty.
Other than that, it's pretty much identical to Monopoly: roll, move, buy land, or pay rent if someone is already owns it. Last player with cash in hand wins.
