Lexio is a game based on the traditional Chinese game system of 'Zhengshangyou', the climbing game, and is virtually the same game as Big Two (also known as Chinese Poker). There are many other card games based on the same mechanism (The Great Dalmuti, Gang of Four, Tichu, etc.), but Lexio uses tiles similar to those in Mah Jong instead of cards, and they are of excellent construction. In accordance with Chinese tradition, the number '2' is the strongest number. The suits are named after the sun, the moon, the stars and the wind. - BoardGameGeek
