Rules of Texas Hold'em
The Flop - the second round of betting
After the first round of betting is complete, the first three community cards are dealt. This is known as the 'flop'.
The Turn - the third round of betting
When all bets have been made in the second betting round, the fourth community card is dealt. This is known as the 'turn'. Another round of betting begins, starting with the first player still in the hand to the left of the dealer.
The River - the fourth round of betting
When all bets have been made in the third round of betting, the fifth and final community card is dealt. This is known as the 'river'. A final round of betting then begins, again starting with the first player to the left of the button.
ShowdownAfter the last round of betting is complete, each player must form the best possible five-card poker hand, made from a combination of their two hole cards and the five community cards. At this point, all players remaining must show their hands, so that the best hand can be determined. The player who has the best hand at showdown wins the pot.
If more than one player has the same winning hand, the pot is split accordingly, which is known as a 'split pot'. When the current hand is complete and before the next can start, the dealer button is passed one position to the left.
