How the cards are dealt

Poker uses a standard deck of 52 cards: thirteen ranks (from two to ace) in four suits. Before dealing, the deck is shuffled — in the simulator, this is done by a cryptographic generator on the server, so the order of the cards cannot be predicted from previous hands.

Each player receives two hole cards, then five community cards are dealt on the table: first the flop (three cards), then the turn (fourth) and the river (fifth). Before the flop, turn, and river, one card is burned — it does not participate in the game. That is why at a table of nine players, 18 + 5 + 3 = 26 cards are used, and 26 remain in the deck.

The winner is determined by the best combination of five cards that can be made from two of your own and five community cards. The evaluator on this page goes through all 21 options of five cards from seven and compares them by rank — taking into account kickers and the possibility of a tie.

Why are there exactly 52 cards in a deck

Four suits with thirteen ranks give 52 unique cards. The number of possible starting hands is 1,326 two-card combinations: C(52, 2) = 52 × 51 / 2. Of these, 78 are pocket pairs, 312 are suited, and 936 are offsuit.

Frequently Asked Questions
Can two players get the same cards?
No. The cards are dealt from a single deck without replacement, so there can't be any repeats: each card exists in a single copy.
What is a burn?
These are cards that are taken from the top of the deck and do not participate in the deal: one before the flop, the turn, and the river. In the simulator, they can be shown with a switch — they do not affect the result.
Why is a hand made up of five cards instead of seven?
Hold'em rules compare the best five cards. Out of the seven available cards, such a five is chosen that gives the strongest combination; the other two are not considered.
How is the winner determined in the event of a tie?
Combinations are compared by rank, then kickers — the lower cards not included in the combination. If they also match, a split is recorded: the pot is divided among the players.
Is this a real money game?
No. The page shows a random hand and hand evaluation, bets are not accepted. This is a training simulator, not a poker room.
