Everyone is familiar with this timeless pastime. The game of blackjack, popularly known as “21,” has gained widespread popularity. In blackjack, you want your hand total to be as close to 21 as possible without going over. For additional information about how to play Blackjack, please refer to my Rules page.


Some casinos may have slightly different blackjack rules than others. The listed ruleset is the most common one used online.

Roulette European

Two decks are used in most games of European blackjack. Some of the rules favor the players, such as limiting the number of decks and allowing the dealer to stand on soft 17.


Because of this, the casino has implemented the “dealer does not check for blackjack” rule. That is to say, the dealer won’t look for a blackjack until the end of the hand. That makes doubling down or splitting pots riskier moves. In some blackjack games, the dealer must first check for blackjack before the hand begins, making double and splitting impossible.


When the dealer has a soft 17, he or she must stand.

When a player has a blackjack and the dealer has one, the game is tied.

Blackjack is checked for just after the hand is over (dealer does not check for blackjack).

Point totals of 9, 10, and 11 are the only ones that qualify for a double down.

The rules of Match Play 21 deviate significantly from those of standard blackjack. There are no 10s in the deck, and certain hands are worth more than others. Similar to Spanish 21, but designed specifically for use in virtual casinos.


The removal of all 10s from the deck leaves only the face cards.

After a player’s first double, the dealer must strike a soft 17.

Pontoon is quite similar to “Spanish 21,” a variant of blackjack. The dealer’s hole cards in this game are initially hidden from the player. The casino compensates for the player’s ignorance by offering 2:1 rather than 3:2 odds.


When your first two cards add up to 21, you have what is called a “pontoon.”

Pontoon pays 2:1 if the dealer has a soft 17.

Those familiar with Pontoon will find many similarities between that game and Spanish 21. In this game, the top 10 cards are discarded. While a larger house advantage would be expected with no 10s in play, Spanish 21 mitigates this by including a number of player-friendly rules.
