Realtime Gaming (RTG) is the leading software provider to American facing online casinos. It offers a reasonable range of blackjack variants that can be accessed from the Table Games tab in its Games menu.

The staple blackjack variants are those that are played in the land casinos. In the land casinos in the United States the dealer checks for blackjack if his face up card is an ace or a ten value card. This variant is listed as simply Blackjack at RTG online casinos. In the land casinos in Europe the game play is slightly different. The second card to the dealer is not dealt up front and therefore he does not check for blackjack. This variant is listed as European Blackjack at RTG online casinos. Another popular land casino variant offered by RTG at its online casinos is Pontoon. In Pontoon both the dealer cards are dealt face down. This gives the player a disadvantage and therefore the Pontoon (which is the equivalent of blackjack) pays 2 to 1 instead of 3 to 2.

Many players prefer the innovative variants of blackjack because they offer something different. RTG has quite a few such blackjack games in its portfolio. One of these is Face Up 21. As the name indicates, both the dealer cards are dealt face up, the opposite of Pontoon. Because of the advantage offered to the player, blackjack hands pay only even money. In normal blackjack games ties push. However in RTG Face Up 21, the player wins blackjack ties but all other ties go to the dealer.

Match Play 21 is another innovative blackjack variant at RTG online casinos. In blackjack games the player must try to get as close to a hand value of 21 without going over and therefore RTG has designated many of its blackjack variants as 21. The main difference in Match Play 21 is that the tens are removed from the decks. This gives a disadvantage to the player, which is made up through a number of bonus hands. The largest of such payouts is for the Match Play hand, which consists of three suited sevens as the first three cards for the player with the dealer face up card being a seven of the same suit.

RTG Super 21 also offers a number of bonus payouts and favorable rules. These are compensated by the regular blackjack paying only even money. The most advantageous rules are that the player can double any time and surrender anytime. Normally these moves are restricted to the dealt hand and are not available if the player hits once. A win with a 5-card or a 6-card hand of value 21 pays out 2 to 1. A 6-card hand valued at less than 21 is an instant win.

Blackjack + Perfect Pairs is another blackjack variant with bonus payouts. But in this game players have to place a side bet in order to be eligible for the bonus payouts. The payouts are for different kinds of pairs dealt up front to the player. A mixed pair pays 6 to 1, a colored pair pays 12 to 1 and a suited pair, called perfect pair, pays 25 to 1. All these blackjack variants are live at RTG online casinos like Club World Casino, Cherry Red Casino and Slots Jungle Casino.
