Poker is a card game where players bet on their own cards and the final outcome is based on the combination of different cards.
Poker became popular because it was easy to play and people would often play for money. It became a form of gambling, but today it is considered a sport because there are many casinos that offer poker tournaments.
In 2007, poker became legalized in Nevada because it was proven to be a game of skill rather than luck. It has also been legalized in other countries such as Australia and France, for example.
