Texas hold'em is a common poker game usually played by 2 to 10 players. Each player will be assigned two hole cards, and then a total of five community cards will be gradually revealed. Players compete by combining the hole cards in their hands with the community cards to form the strongest five cards possible. There are betting rounds in the game, and players can choose to raise, call, check, fold, or go all-in. Finally, the players remaining in the game will show off their cards to determine the final outcome. Combining luck, strategy and psychological tactics, Texas Hold'em is a very popular competitive poker game and is widely regarded as one of the most challenging poker games.
