In a game of Texas hold'em, each player is dealt two cards face down (the 'hole cards')
Over several betting rounds, five more cards are (eventually) dealt face up in the middle of the table
These face-up cards are called the 'community cards.' Each player is free to use the community cards in combination with their hole cards to build a five-card poker hand.
Discovering how to play Texas hold'em poker is not difficult and the simplicity of its rules, gameplay, and hand-ranking all contribute to the popularity of the game.
The Flop: the first three community cards.
The Turn: the fourth community card.
The River:The fifth and final community card.
