Play Online Blackjack at UK-Licensed Casinos

Blackjack is one of the most popular card games in the world... It’s fast, strategic, and offers some of the best odds in the casino.

How does online blackjack work?

The goal is simple: get as close to 21 as possible without going over – and beat the dealer’s hand. It’s a mix of luck and smart decision-making.

Is blackjack a game of skill or luck?

Both. Blackjack has one of the lowest house edges in the casino – as low as 0.5% when played with perfect strategy. While you can’t control the cards, learning basic strategy can improve your odds significantly.

Blackjack - FAQ

🂡 What is Blackjack?

Blackjack (a.k.a. 21) is a card game where you compete against the dealer to get a hand value closer to 21 without busting. Number cards count as face value, face cards 10, and Aces 1 or 11.

🔢 How is the RTP calculated?

Using optimal basic strategy, classic 6-deck blackjack with 3:2 payout and dealer stands on soft 17 offers an RTP around 99.5% (house edge 0.5%). Variations and side bets change this.

📜 What is Basic Strategy?

Basic Strategy is a mathematically derived chart telling you when to hit, stand, double or split based on your hand and the dealer’s up-card. Following it minimises the house edge.

🃏 What are common rule variations?

Payout: 3:2 (best) vs 6:5 (worse)
S17/H17: Dealer stands or hits on soft 17
Double: Allowed on any 2 cards or 9-11 only
Resplit Aces: Allowed / not allowed
Number of decks: 1 to 8 (fewer decks = lower edge)

🎁 Are side bets worth it?

Side bets (Perfect Pairs, 21+3, Bet Behind, etc.) offer big payouts but higher house edge (5%-10%+). Fun for small stakes, but not optimal for RTP seekers.

👥 What is Live Blackjack?

Live Blackjack streams a real dealer and shoe. The table may allow 7 seats plus Bet Behind. Evolution’s Infinite/Power/Free Bet variants scale to unlimited players.

💳 Minimum & maximum bets?

Online RNG blackjack starts at £0.10. Live tables usually range £1–£5 up to £10k+. VIP Salon Privé tables can exceed £25k per hand.

♠️ When should I split or double?

Basic Strategy says: always split A-A & 8-8; never split 5-5 or 10-10. Double 11 vs any dealer card, 10 vs 9 or less, and 9 vs 3-6. Deviations depend on exact rules.

🔄 Can I surrender?

Late Surrender lets you forfeit half your stake after the dealer checks for blackjack—cuts losses on tough hands (e.g., 16 vs Ace). Not all tables offer it.

🧮 Is card counting possible online?

No for RNG games (decks reshuffled each hand). Limited for live tables—continuous shuffle machines or frequent shoe swaps make counting impractical.

❓ Should I take insurance?

Insurance pays 2:1 if the dealer has blackjack but has a house edge of ~7%. It’s generally not recommended unless you’re counting cards.

📱 Is mobile blackjack safe?

Yes—HTML5 and live casinos run securely in mobile browsers or apps. Touch controls adapt to smaller screens without affecting fairness.

🧠 How do I play responsibly?

Set session bankrolls, stick to basic strategy, and use deposit/time limits. Take breaks and never chase losses.
