Poker is a card game played between two or more players and usually involves betting on your hand. The highest hand wins the pot. The cards are drawn from a standard 52-card deck, with aces being high and other cards having different ranks (from lowest to highest: hearts, diamonds, clubs). Some games add extra cards called jokers that can take on any suit and rank.
In the beginning of each round players place bets into a pool in the center of the table (the “pot”) to create an incentive for people to play their hands. Players buy chips, which represent money, in the amount that the game designer specifies for each type of bet. A white chip is worth a certain number of ante/bet dollars, red chips are worth five whites, and blue chips are worth ten whites.
Once the ante/bet has been placed two cards are dealt to each player. If you have a good hand you can call the bet of the person to your left or raise it.
After the first round of betting is complete a third card is put on the table that anyone can use (this is called the flop). Then another round of betting takes place.
The next step is the fourth and final betting round which reveals the fifth and last community card (this is called the river). After this there is a Showdown where each remaining player reveals their hand and the highest one wins the pot.
