Playing cards were probably invented in China during the Tang Dynasty (618–907 CE) though they were rather different to the ones that we are familiar with today. There is a reference to something called the ‘leaf game’ being played by Princess Tongchang in 868 CE but it is unclear exactly what these leaves were. We know that this game often involved drinking – it was reported that the Emperor Muzong went on a 25-day drinking spree in the year 969 and on New Year’s Eve (26th February) “he played the game of leaves with his ministers”. This game would have been yezi ge (Rules of Leaves) but as long ago as 1067 CE it was recorded that there was no one alive who remembered how to play the game.
