Play Online Blackjack: RNG Games, Live Dealer Tables and Every Variant in Between
Play online blackjack at Conquer Casino with a choice of RNG (computer-dealt) games and live dealer tables. Whether you prefer playing at your own pace with no time pressure or sitting across from a real dealer streamed in HD, we’ve got you covered. Our blackjack library includes classic single-hand games, multi-hand variants, European and American rules, plus innovative titles like Blackjack Switch, and our full live blackjack range from Evolution and Playtech.
Blackjack is one of the few casino games where your decisions directly affect the outcome. With a house edge as low as 0.5% when played with basic strategy, it’s also one of the best-value games in any casino. That combination of skill and favourable odds is exactly why blackjack online remains one of the most popular card games for UK players. Whether you’re new to UK blackjack or an experienced player looking for more variants, there’s something here for every level.
Conquer Casino has been live since 2012 and holds UKGC licence 39335. Every blackjack game on the site is independently tested for fairness, works on desktop and mobile, and is available to play for real money around the clock.
How Online Blackjack Works
The objective is simple: get a hand value closer to 21 than the dealer without going over. Card values are straightforward:
| Card | Value |
|---|---|
| 2-10 | Face value |
| Jack, Queen, King | 10 |
| Ace | 1 or 11 (whichever benefits your hand) |
A “natural blackjack” is an Ace plus any 10-value card dealt as your first two cards. This pays 3:2 at standard tables, meaning a £10 bet returns £25 (your £10 stake plus £15 winnings).
Player Decisions
After receiving your first two cards, you have several options:
- Hit – take another card to increase your hand total.
- Stand – keep your current hand and end your turn.
- Double Down – double your bet and receive exactly one more card. Best used on strong starting hands like 10 or 11.
- Split – if your first two cards are a pair, you can split them into two separate hands, each with its own bet.
- Surrender – available in some variants. Fold your hand and receive half your bet back. Useful against a strong dealer up card.
- Insurance – offered when the dealer shows an Ace. A side bet paying 2:1 if the dealer has blackjack.
Carries a house edge over 7% and is generally not recommended
The dealer follows fixed rules – typically hitting on 16 or less and standing on 17 or more. This means the dealer has no decisions to make, while your choices are what determine the outcome.
RNG Blackjack Games
RNG (random number generator) blackjack games are computer-dealt. There’s no live dealer and no other players at the table. You play at your own pace, take as long as you want on each decision, and the results are determined by certified random number generator software.
RNG blackjack is ideal for:
- Learning the game without time pressure.
- Practising basic strategy at your own speed.
- Playing at lower stakes (often from £0.10 per hand).
- Quick sessions when you don’t want to wait for other players.
RNG Blackjack Variants
| Variant | Key Feature | Decks | RTP |
|---|---|---|---|
| Classic Blackjack | Standard rules, single hand | 6 or 8 | 99.50%+ |
| European Blackjack | Dealer receives second card after players act (no peek rule) | 2 | 99.60% |
| American Blackjack | Dealer peeks for blackjack with Ace or 10 showing | 6 or 8 | 99.50% |
| Multi-Hand Blackjack | Play up to 5 hands simultaneously | 6 | 99.50%+ |
| Blackjack Switch | Play two hands and swap the top cards between them | 6 or 8 | 99.87% |
| Pontoon | British variant with different terminology (twist/stick/buy) | 8 | 99.64% |
| Double Exposure | Both dealer cards dealt face up | 8 | 99.33% |
| Single Deck Blackjack | Played with one deck for improved odds | 1 | 99.83%* |
| Atlantic City Blackjack | Late surrender option; dealer stands on all 17s | 8 | 99.65% |
*RTP can vary based on specific rule sets and payout structures. Some single-deck games pay 6:5 on natural blackjack instead of 3:2, which significantly increases the house edge.
Understanding the Rule Differences
The differences between variants might seem small, but they affect the house edge and your optimal strategy.
Number of decks matters. Fewer decks generally favour the player. A single-deck game has a lower house edge than an 8-deck game, all else being equal. However, casinos often adjust other rules (like reducing blackjack payouts to 6:5) to compensate.
Dealer peek vs no peek is the key difference between American and European rules. In American blackjack, the dealer checks for blackjack when showing an Ace or 10 before players act. In European blackjack, the dealer doesn’t peek, which means you could double or split against a dealer who turns out to have blackjack – losing more than your original bet.
Surrender is available in some variants (like Atlantic City) and not others. When available, it’s a valuable option against strong dealer up cards. Surrendering a hard 16 against a dealer 10, for example, is mathematically correct.
Blackjack payout should always be 3:2. Avoid any game that pays 6:5 on natural blackjack, as this nearly triples the house edge compared to the standard payout.
Live Dealer Blackjack
For players who want the social atmosphere and transparency of a real dealer, our live blackjack tables deliver exactly that. All live blackjack games are streamed in HD from professional studios operated by Evolution and Playtech.

Basic Strategy
Basic strategy is a mathematically calculated set of optimal decisions for every possible hand combination. It tells you exactly when to hit, stand, double, split, or surrender based on your hand and the dealer’s up card. Following basic strategy reduces the house edge to its lowest possible level – around 0.5%.
Here are the most important basic strategy rules to remember:
When to Hit
- Hit on hard 8 or less (always).
- Hit on hard 12 against a dealer 2 or 3.
- Hit on hard 12-16 against a dealer 7 or higher.
When to Stand
- Stand on hard 17 or higher (always).
- Stand on hard 13-16 against a dealer 2-6.
- Stand on soft 19 or higher (Ace + 8 or better).
When to Double Down
- Double on hard 11 against any dealer card except Ace.
- Double on hard 10 against a dealer 2-9.
- Double on hard 9 against a dealer 3-6.
When to Split
- Always split Aces and 8s.
- Never split 10s or 5s.
- Split 2s, 3s, 6s and 7s against a dealer 2-7.
- Split 9s against a dealer 2-9 (except 7).
When to Surrender
- Surrender hard 16 against a dealer 9, 10, or Ace.
- Surrender hard 15 against a dealer 10.
These guidelines apply to standard multi-deck blackjack. Some variants have adjusted strategies – for example, the optimal play in Blackjack Switch differs because you can swap cards between hands.
Full basic strategy charts are freely available online and easy to reference while playing RNG blackjack. There’s no rule against using them, and we’d recommend it, especially if you’re still learning.
Blackjack House Edge Comparison
The house edge varies between blackjack variants depending on the specific rules in play. Here’s how the main options compare.
| Game Type | House Edge | Notes |
|---|---|---|
| Classic Blackjack (basic strategy) | 0.50% | Standard 3:2 payout, multi-deck |
| Single Deck Blackjack (3:2 payout) | 0.17% | Best odds, but rare online |
| Single Deck Blackjack (6:5 payout) | 1.45% | Avoid – significantly worse odds |
| European Blackjack | 0.40% | No peek rule; 2 decks |
| Blackjack Switch | 0.13% | Card swapping offsets dealer 22 push rule |
| Pontoon | 0.36% | Five-card trick rule benefits the player |
| Atlantic City Blackjack | 0.35% | Late surrender reduces edge |
| Live Blackjack (basic strategy) | 0.50% | Same rules as standard RNG blackjack |
| Average Slot Machine | 3-5% | For comparison |
Blackjack with basic strategy offers a dramatically lower house edge than slots and most other casino games. The difference between 0.5% and 4% compounds significantly over hundreds of hands, which is why skilled blackjack players tend to get better long-term value than slot players.
Side Bets
Many blackjack games – both RNG and live – offer optional side bets alongside the main game. These are independent wagers resolved separately from your hand.
| Side Bet | How It Works | Typical House Edge |
|---|---|---|
| Perfect Pairs | Pays if your first two cards form a pair (mixed, coloured, or perfect) | 4-11% |
| 21+3 | Combines your two cards and the dealer’s up card into a poker hand | 3.6% |
| Insurance | Pays 2:1 if the dealer has blackjack (offered when dealer shows Ace) | 7%+ |
| Hot 3 | Based on the combined value of your cards and the dealer’s up card | 6% |
| Bust It | Wager on whether the dealer will bust | Varies |
Side bets carry a significantly higher house edge than the main game. They add excitement and the potential for larger payouts on specific combinations, but they’re best treated as occasional extras rather than a core part of your strategy.
RNG vs Live Blackjack
Both formats are available at Conquer Casino. Here’s how they compare.
| Feature | RNG Blackjack | Live Blackjack |
|---|---|---|
| Dealer | Computer | Real person, streamed in HD |
| Pace | As fast as you click | Set by dealer and other players |
| Minimum Stake | Often from £0.10 | Typically £1-£5 |
| Time Pressure | None – play at your own speed | Decision timer on each hand |
| Other Players | None | Up to 7 (or unlimited on Infinite/Power) |
| Social Interaction | None | Live chat with dealer |
| Side Bets | Some variants | Most tables |
| Demo Mode | Available on most games | Not available |
| Strategy Practice | Excellent – no time limit | Possible, but timer adds pressure |
| Transparency | RNG certified by independent labs | Physical cards dealt on camera |
Choose RNG blackjack if you want to learn at your own pace, play at lower stakes, or fit in quick sessions without waiting for other players.
Choose live blackjack if you want the social experience, prefer watching physical cards being dealt, or enjoy the atmosphere of a real casino table.
