Play Blackjack Online at Top UK Casinos in 2025

How to Play Blackjack Online at UK Casinos

Blackjack has evolved over the centuries from a card game that originated in the 17th century to one of the most popular games at UK online casinos.

While today there are numerous online blackjack real money variants, at its core it’s a very simple game that involves trying to beat the dealer by getting a hand worth closer to 21 without going bust. The best hand is known as ‘blackjack’ or ‘natural’, and comprises an ace and a 10-value card. It’s an instant win in all blackjack variants.

• In a blackjack online game, you set your bet amount and wait for you and the dealer to be dealt cards. You then have the following options depending on the variant you’re playing:
• Hit: Add another card to your hand. You can keep hitting in online blackjack until the value of your hand exceeds 21 or you decide to stand.
• Stand: Submit your hand for that round.
• Split: If you’re dealt a pair of cards, you can double your bet to split it into two separate hands. This is often recommended if you’re dealt a pair of 7s or 8s.
• Double down: You can double your wager to get a third and final card for your hand. This is suggested if you’re initially dealt a hand worth 10 or 11.
• Insurance bet: If the dealer’s face-up card is an ace, you can place an insurance bet worth half of your original bet if you think they have blackjack.
• Surrender: Some blackjack variants incorporate the surrender rule, which allows you to fold your hand and receive half of your wager back. This is a good option if you have a bad starting hand.
• Side bet: Some blackjack online games allow you to wager side bets, which reward special payouts if you and/or the dealer are dealt certain cards.

Playing online blackjack for real money relies on making the right moves to beat the dealer. Unlike other table games such as roulette, you can rely on probability to help you out and make decisions based on what’s most likely to happen. Learning basic blackjack strategy is recommended if you want to play at blackjack online casinos.
