The classic game of GO is easy to learn but incredibly deep and difficult. This is a great set because it stores nicely.
From the manufacturer:
Our most popular Go set! This GO game includes a beautiful wood board with pull-out drawers for storing stones when not in use. Go is an ancient game of Chinese origin that rewards patience and concentration rather than greed and aggression. The shifting balance of territory and power can unnerve even the most disciplined and intellectual player.Buy it on Amazon
