Play – The Basics
The main goal within any blackjack game is to reach 21 or obtain a higher hand than the dealer without going over 21, called a “bust.” The game is played by comparing cards within the dealer, and action can be taken to improve your chances within the game.
While playing real money blackjack, all bets are placed before the game begins. The main bet against the dealer pays out even money or 3:2, depending on the blackjack game.
Blackjack commences with two cards being dealt to the dealer and the punter in play. One of the dealer’s cards is face down (hole card), and every other card in play is an up card.
The player takes action first, totalling their own hand and taking the dealer’s up card into account. Here the player can either hit, stand, double down, split or surrender in some blackjack variations. The dealer then reveals the hole card and must play their hand as stated by the game. In the event the dealer has a hand totalling 16 or less, the dealer will continuously hit until the hand reaches or exceeds 17. If the hand is 17 or above, the dealer must stand.
The nearest hand to 21 while beating the other participant wins the game, and all bets are paid out accordingly.
Types of Blackjack Games
Unlike other casino games, there is an excess amount of online blackjack games for real money—all differing with added moves and payouts. Whether you love to play European blackjack or enjoy spicing your gameplay up with multi-hand blackjack, there is something for everyone within UK blackjack platforms on offer at Casino Martini.
Here are some of the many variations you can anticipate at the best blackjack sites in 2025.
Blackjack Switch – Blackjack Switch is played with two hands at once. The beauty of this game is that players can switch cards between both hands at any stage of the game. This offers double the chance of beating the dealer.
Blackjack Surrender – Blackjack Surrender gives the player the opportunity to forfeit their hand and only lose half of their original stake if they feel they have a failing hand. This move can be used either as a late surrender or an early surrender. Both moves give players the chance to opt out of the game and save half of their bet amount.
Double Exposure Blackjack – As the name may suggest, within double exposure blackjack, both of the dealer’s cards are exposed. The lack of a hole card allows players to make more informed decisions on their hand, minimizing some risk within the game. However, this does come at a price as the payouts are not as high as other blackjack variants.
Single Deck Blackjack – Single deck blackjack is one of the easiest blackjack games to begin learning. On the other side of the spectrum, card counters should also start with lower decks while practising a card counting system such as high/low card counting.
Pontoon – Pontoon is the British game of blackjack we all know and love. The rules within this version of blackjack are considerably different from the classic game. Players can double with more than two cards which have proven enriching for our team in the past.
Progressive Blackjack – Progressive blackjack provides an additional progressive jackpot which every player has a chance at winning. Before the game begins, players have the option to place a side bet toward the jackpot in addition to their main bet. Most progressive blackjack games payout accordingly as a player obtains a number of Aces within their hand.
Perfect Pairs Blackjack – Perfect Pairs Blackjack offers players a side bet with the hope they will land a perfect pair. Any pair of the same cards will be rewarded with a payout depending on the side bet amount.
21+3 Blackjack – Another interesting side bet which can be found within 21 + 3 Blackjack combines luck with poker hand knowledge. Here is the play has any 3 card poker combination from the cards on the table they win the side bet.
Multi-hand – Within multi-hand, blackjack players can wager with multiple hands simultaneously, dramatically increasing the chances of beating the dealer.
Ensure that the blackjack bonus funds you have claiming can be used within your chosen variant. Most online casinos allow players to wager their bonus funds throughout the casino. However, there are some exceptions at some gambling sites.
Betting Strategies
The low house edge within blackjack games is a huge attraction for new gamblers. This figure sits around 2% for new players learning this classic table game. To lower this even further, 0.5% to be exact, players can implement a basic blackjack strategy.
The basic strategy within blackjack is simply a card dictating the correct action depending on the cards in play. Betting systems can also be effective if you are lucky enough to obtain a winning streak within the game. Depending on your bankroll size, test out progressive, non-progressive betting systems or flat betting.
Mobile Blackjack
