Some documents say that playing cards were invented by the Chinese Emperor Mu-tsung. At first, these cards were not made of paper like today, but were made of bone, wood or horn. These card games were used in festivals and court entertainment. The Chinese used these cards as a means of betting or just for fun, just like how we use playing cards today.
