GREAT KINGDOM - How to Play

About Great Kingdom, from BoardGameGeek:

Building a kingdom is no easy task - more so if your enemy is trying to occupy the same territory. Build the biggest kingdom by strategically placing your own castles and destroying the enemy's: a single enemy castle is enough to win the game. Great Kingdom simplifies Go without taking the fun away for experienced players, making it the perfect gateway into the world of Go. It is the first of three games of the game series WIZSTONE, developed by Go grandmaster Lee Sedol. -description from the publisher
