In poker, particularly in games like Texas Hold'em, community cards are shared cards placed face-up on the table. These cards are used by all players to create their best possible hand. Each player combines their own private cards, known as hole cards, with the community cards to form a winning combination. Community cards are revealed in stages: the flop (three cards), the turn (one card), and the river (one card). This unique feature adds excitement and strategy to the game, as players must decide how to use the community cards to outsmart their opponents and win the pot.
