Poker is a card game that involves betting, raising and re-raising. There are several poker variants, but the basic rules are the same in all. The game is usually played with poker chips, which are small discs of varying colors and values. A white chip is worth a minimum ante or bet; a blue or red chip is typically worth more than a white one. Players buy in for a set amount of chips before the cards are dealt.
After all players have received their two hole cards, a round of betting begins. The player to the left of the big blind has the first turn, and can choose to call the bet (place a bet equal to the player to their right), raise it (place a bet double the size of the big blind), or push their cards face down without placing any chips in the pot (fold).
Once all players have placed their bets, 3 more community cards are dealt. There is another round of betting, and the player with the best 5-card hand wins the pot.
The highest hand is a royal flush, which includes a 10, Jack, Queen, King and Ace of the same suit in sequence. A straight is five consecutive cards of the same rank, such as Ace, Two, Three, Four and Five. A pair is two matching cards of the same rank, such as two aces or two sixes. And a three of a kind is three cards of the same rank, such as three jacks or three sixes.
