Poker is a card game involving betting where players have the opportunity to win money by having a winning hand. It is a family of gambling games and the rules vary by game.
A standard pack of 52 cards is used (although in some games there are multiple packs and the use of wild cards). Cards rank from high to low: Ace, King, Queen, Jack, 10, 5, 6, 7, 8, 9; and suits have no relative ranking (although in some variants a flush beats a straight). Some games also allow the use of Wild Cards which take on whatever suit or value their possessor desires.
In most poker games the object is to win a pot, which is the sum total of all bets made by each player during a single round of betting. Each player makes an initial bet and then either calls or folds during subsequent rounds of betting. The highest hand wins the pot.
It is important not to get too attached to a hand. Pocket kings on the flop are a strong hand but an ace could spell disaster if it turns up, and a board full of flushes or straights is cause for great caution. Good bluffing skills are also essential and can help improve your chances of winning. It is also vital to understand that luck can change at any time and you should always keep some cash in reserve in case your lucky streak turns into a drought!
