Poker is a card game where the players put in a sum of money, called a pot, to play. The player with the highest hand wins this pot. The hand can be a combination of cards of any rank and suit, but the higher the ranking of the card, the better the hand. The game requires both luck and skill. Over time, skill will virtually eliminate the variance of luck.
Each round of betting begins with 2 mandatory bets (called blinds) placed into the pot by the players to the left of the dealer. These bets create an incentive to play and help balance the odds for all players.
After the players have received their 2 hole cards, another card is dealt face up on the flop. The players can then bet again. A player can fold if he does not like his cards or wants to leave the round of betting.
Then a final card is dealt face up on the river. There is one last round of betting before all cards are revealed in a showdown. The best 5 card poker hand wins the pot.
