The community cards poker term refers to all shared cards every player at the table can use to make the best possible hand.
Most notably, the community cards gameplay feature is present in Texas Hold’em and Omaha poker variations.
The community cards always unfold in the same specific order. In the first phase, the dealer puts three community cards on the board, called the flop.
After that, they add another card, called the turn or the fourth street. Lastly, they deal the fifth community card, called the river.
This full set of shared cards is called the board.
