Klotski is an ancient Chinese game. It is collectively called "China's puzzle" with Tangram and Nine Links due to its variety and endless play characteristics. Together with France's "Indie Diamond" and Hungary's "Cube", it is called the three incredible puzzles. The Huarong Road game is based on the famous Three Kingdoms story: the end of the Eastern Han Dynasty, the world disputes, the heroes rise together, Sun Quan and Liu Bei's coalition forces burned Chibi and broke Cao Cao's millions. Cao Cao was defeated by Huarong Road and met Guan Yu on a narrow road. Guan Yu explained Cao Cao and interpreted a classic story of catching and releasing Cao.
