Best blackjack apps UK

How we chose the best blackjack apps

Blackjack is the same card game on every licensed app, but the rules at each table, and the app around it, are not. We ranked apps on what you can check before you play: the app's own features, how quickly and cheaply it pays out, how you reach support, and whether its bonus terms are honest about table games.

What we could not do is rank by blackjack range. None of these operators publishes a full list of its tables, so we never claim an app carries a particular variant. Treat the ranking as a guide to the app and its money side, then use the checks later on this page to pick a good table inside it. The full set of lists is on our best casino apps hub.

Best blackjack apps UK, ranked

1. Casumo: best app for live blackjack on a phone

Casumo's iPhone app runs on iOS 15.0 or later at 52.5 MB, and its listing includes Face ID and Touch ID login, Quick Deposit with Apple Pay and a haptic feedback toggle, small touches that help when you are making quick hit or stand decisions. On Android the app is titled "Casumo - Live Casino & Slots". The listing does not name blackjack specifically, so check the Casumo games lobby for live and RNG tables.

Casumo says PayPal, Apple Pay and e-wallet withdrawals arrive instantly after approval. Its bonus is the most blackjack-relevant detail: game restrictions apply, and a £5 maximum bet runs while the bonus is active, so most players will want to play blackjack with cash, not bonus funds. Support runs 7:00 to 23:00.

2. 10bet: best for phone support at the table

10bet's app combines its sportsbook with a casino that its listing says includes live casino tables. It needs iOS 16.0 or later and takes 112.3 MB. The standout is a published UK phone line, 0808 175 0550, open 08:00 to 23:00, which is handy if a hand is settled in a way you want explained. See the 10bet games page for what the lobby holds.

Card and e-wallet withdrawals take up to 2 business days. Its welcome bonus is wagered on slots, so it adds little for a blackjack player.

3. Coral Casino: the only listing that names blackjack

Coral's App Store listing is the only one of the three to name blackjack directly, alongside roulette and live casino. It is a standalone casino app (101.6 MB, iOS 18.0 or later), and Coral says it charges no withdrawal fees, with Visa Fast Funds payouts usually approved within a couple of hours and then landing in up to 4 hours. Browse the Coral games guide for more.

It ranks third because the iOS 18 requirement rules out many older iPhones and no phone support is published. Its welcome spins are for slots only.

Blackjack rules that change the house edge

Every blackjack table publishes its rules in the game's help screen, and small rule changes add up. These figures come from Wizard of Odds' rule variations table (opens in a new tab), measured against an eight-deck game where the dealer stands on soft 17.

The payout rule matters most. At 3:2 a £10 blackjack wins £15; at 6:5 it wins £12. That £3 gap, repeated every time you are dealt a natural, is why the 6:5 rule costs more than the dealer hitting soft 17 and no doubling after splits put together. Our blackjack app guide covers the full rules.

What blackjack costs per 100 hands

With the edge known, the cost is simple: stake × hands × house edge. These examples assume you play basic strategy; mistakes push the cost up.

Despite its name, Free Bet Blackjack does not hand out money: its no-cost doubles and splits are paid for by a rule that a dealer 22 pushes, which is why its edge is more than double Infinite Blackjack's. Read about Infinite Blackjack and the rest of our house edge by game figures.

These are long-run averages. Over a single session of 100 hands your result will usually differ from the expected cost by far more than the cost itself, in either direction.

Live blackjack vs RNG blackjack on a phone

Blackjack apps offer two kinds of table. RNG blackjack is software: a tested random number generator deals each hand, and most online games shuffle after every hand. Live blackjack is dealt by a real dealer on camera from a shoe of physical cards.

• Pace. UK rules require at least 5 seconds per game cycle for casino games other than slots, so even RNG tables cannot be rapid-fire. Live tables run at the dealer's pace.
• Seats. Classic live tables have seven seats; Bet Behind lets you back a seated player's hand instead. Evolution's Infinite tables have unlimited seats, with everyone sharing the same first two cards.
• Screen. RNG games scale cleanly to a small screen. Live games need a steady connection and are easier to follow on a larger phone or in landscape.
• Data. Live streams use much more data than RNG tables, so Wi-Fi is the safer option.

Our guide to live blackjack on mobile goes further, and Evolution's live blackjack page (opens in a new tab) lists the studio's main variants. Remember that each app chooses which tables to carry.

Basic strategy on a blackjack app

Basic strategy is the mathematically best decision for each hand against each dealer card. It reduces the house edge to the figures above; it never removes it. For four to eight decks with the dealer standing on soft 17, Wizard of Odds' basic strategy chart (opens in a new tab) includes these principles:

1. Always split aces and 8s.
2. Never split 5s or 10s.
3. Always stand on hard 17 or more.
4. Stand on hard 13 to 16 only when the dealer shows 2 to 6.
5. Double hard 11 unless the dealer shows an ace.
6. Never take insurance or even money.

Strategy changes with the rules: no-hole-card European games and dealer-hits-soft-17 tables use slightly different charts. See blackjack strategy on mobile for more.

Blackjack side bets: what they really cost

Side bets are where blackjack apps make the game expensive. Each one is a separate wager with its own, much higher, house edge. Figures below are from Wizard of Odds' published analysis for the paytables named.

Compare those with 0.45% to 0.62% on the main game. A £1 side bet on every £10 hand can easily double what an hour of blackjack costs you. Read more about side bets.

Does card counting work on blackjack apps?

No. Card counting is a historical idea: the mathematician Edward O. Thorp popularised it in a 1962 book, and it relies on tracking cards through a shoe that is not reshuffled. RNG blackjack shuffles after every hand, so there is nothing to track. Live tables generally use shuffling methods, such as continuous shufflers or reshuffling well before the shoe runs out, that defeat it too.

Apple's App Store Review Guidelines (opens in a new tab) also ban illegal gambling aids, including card counters, from the store. Be wary of any app or video that promises a way past the house edge; no system changes it.

Welcome bonuses and blackjack apps

Most welcome offers are designed for slots. Blackjack, roulette and live tables are often excluded or count for less towards wagering,. That applies to all three apps here: Casumo says game restrictions apply, 10bet's bonus is wagered on slots, and Coral's offer is spins on selected slots.

The honest advice is to choose a blackjack app for its tables and payouts, not its bonus, and to read the terms before you take bonus money near a card table. Our guide to reading casino app bonus terms shows where the game rules sit.

Other UK blackjack apps worth knowing

These licensed brands are relevant to blackjack players but are not ranked, because we only rank our partners against full published facts.

• Sky Casino: its iOS app is listed as "Sky Casino Blackjack, Roulette" (155.9 MB, iOS 15.0 or later), covering blackjack, roulette, baccarat, slots and live casino.
• Betfair Casino: the "Betfair Live Casino" iOS app lists live blackjack, roulette and baccarat, though its iOS 9.0 requirement suggests an older listing.
• Virgin Games: Gamesys's site lists table games including blackjack, roulette, baccarat and craps.
• 888casino: third-party reviews mention exclusive 888-branded live blackjack tables; its UK app listing could not be confirmed.

How to check a blackjack table in any app

1. Open the blackjack game but do not place a bet.
2. Tap the information or help icon inside the game.
3. Find the blackjack payout: you want 3 to 2.
4. Check whether the dealer stands or hits on soft 17, and whether you can double after splitting.
5. Look for the RTP figure, which UK games must make available, and compare tables.
6. Note the table's minimum and maximum bets, and set a deposit limit that fits your budget.

Blackjack app offers and their terms

These three offers come from our ranked blackjack apps, but none is aimed at blackjack: table games are often excluded or count for less, so check the terms. All are for new customers aged 18+, and terms apply.
