What is Online Blackjack?
How It Works
Blackjack is a card game where your goal is to beat the dealer by getting a hand total closer to 21 — without going over. You and the dealer each receive two cards. You then choose to hit (take another card), stand (hold), double down, or split pairs. The dealer must stand on 17 or above.
House Edge & RTP
Blackjack has one of the best RTPs in the casino — up to 99.5% when you use basic strategy correctly. The house edge is just ~0.5%. By comparison, most slot games sit at 94–97% RTP. Your decisions directly influence the outcome, unlike slots.

Basic Strategy — When to Hit, Stand, Double & Split
Basic strategy is the mathematically optimal play for every hand. Memorise these core rules to reduce the house edge to 0.5%.
Hit
- • Hard 8 or less — always hit
- • Hard 12–16 vs dealer 7+
- • Soft 13–17 (Ace + 2–6) vs most dealer cards
Stand
- • Hard 17 or more — always stand
- • Hard 13–16 vs dealer 2–6
- • Soft 19 (Ace + 8) or above
Double Down
- • Hard 11 — double vs dealer 2–10
- • Hard 10 — double vs dealer 2–9
- • Hard 9 — double vs dealer 3–6
Split
- • Always split Aces and 8s
- • Never split 10s or 5s
- • Split 2s and 3s vs dealer 2–7
Note: Basic strategy varies slightly by number of decks and dealer rules. These rules apply to standard 6-deck blackjack (dealer stands on soft 17).

What is the best RTP for online blackjack?
Online blackjack using basic strategy returns up to 99.5% RTP — one of the highest of any casino game. The house edge is around 0.5% when played optimally.
Can you count cards at online blackjack?
No. Online blackjack — both RNG and live — uses continuous shuffle machines or regular shoe re-shuffles, making card counting ineffective.

Both are legitimate options. Live blackjack offers a real casino atmosphere with human dealers, while RNG blackjack is faster and available for lower stakes. RTP is comparable.
What are the minimum stakes for online blackjack in the UK?
Stakes vary by table. RNG blackjack can start from as little as £0.10 or £0.25. Most live blackjack tables start at £1–£5 per hand.
Is online blackjack rigged?
Not at UKGC-licensed casinos. RNG blackjack is independently audited, and live blackjack uses physical cards dealt by real dealers under CCTV.
