Why and how were card games invented?

Card games are believed to have been invented in China during the Tang dynasty (618-907 AD) as a form of entertainment and social interaction. The earliest known card games likely evolved from games using paper money or tiles, reflecting the cultural and social practices of the time. As trade expanded, these games spread to other regions, adapting to local customs and leading to the diverse array of card games we see today. The invention of cards allowed for strategic play and gambling, making them popular across various societies.
