Blackjack is a comparing card game between a player and dealer, meaning players compete against the dealer but not against other players. It is played with one or more decks of 52 cards. The objective of the game is to beat the dealer in one of the following ways: Get 21 points on the player's first two cards (called a "blackjack" or "natural"), without a dealer blackjack; Reach a final score higher than the dealer without exceeding 21; or Let the dealer draw additional cards until his or her hand exceeds 21.

Like the common poker game formats, Ultimate Texas Hold ‘em is played with a single, regular 52-card deck. Towards the end of the game, the dealer and the players left use any combination from their own two cards and the five community cards in order to come up with the best possible hand for themselves. The dealer will only be able to open if they possess at least a paired board. The play, ante, and blind bets are graded, depending on who wins, and whether the dealer will open. Wikipedia
