When and where was poker discovered?

Answer 1

There seem to be differences of opinion on the origin of Poker. Moreover, there seems to be no clear or direct early ancestor of the game. It is more likely that Poker derived its present day form from elements of many different games. The consensus is that because of it's basic principal, its birth is a very old one.

Jonathan H. Green makes one of the earliest written references to Poker in 1834. In his writing, Green mentions rules to what he called the "cheating game," which was then being played on Mississippi riverboats. He soon realized that his was the first such reference to the game, and since it was not mentioned in the current American Hoyle, he chose to call the game Poker.
