Texas Holdem is the most popular form of poker, and it reigns supreme at South Sudan's mobile casinos. The rules of Texas Holdem are pretty straightforward. Each player is dealt two private cards, known as hole cards, and there are five community cards that everyone shares. After the initial two cards are dealt, betting begins. Players can choose to fold, call (match the amount of what the player before them bet) or raise (place a bet higher than the previous bet). After the betting round is finished, the dealer flips over three of the five community cards. This round is known as the flop. After the flop, players will have two rounds of betting with the same structure as the initial round. After the betting is finished, the fourth community card is revealed, known as the "turn." After another round of betting, the fifth and final card, called the "river," is revealed. Players must make the best five-card poker hand with the seven cards that they have. After the final round of betting, the players show their hands, and whoever has the best hand wins the pot.
