Types of Blackjack: Best & Worst Ranked By House Edge
If you’re thinking about playing blackjack at a UK online casino, understanding the differences between game versions can help you make more informed choices.
Rules can vary between games—some increase the casino’s edge, while others may be more favourable, depending on how you play.
This guide explains the house edge, compares some common blackjack types, and highlights a few key rules that can affect gameplay.
Since casinos and game libraries can differ, it may be worth checking the rules before you start. If you’re new to blackjack, this guide is designed to be simple and easy to follow.
How Many Different Types of Blackjack Games Are There?
Blackjack is one of the most played card games in UK casinos, both online and in physical venues. At its core, blackjack is simple: try to get as close to 21 as possible without going over. However, small rule changes between different versions can have an effect on your chances.
In UK casinos, you may come across versions such as:
Classic Blackjack
European Blackjack
Vegas Strip Blackjack
Blackjack Switch
Single Deck Blackjack
Free Bet Blackjack
Some blackjack games are standard, while others are designed by software providers and may include special rules or features.
For example, some may allow players to split cards multiple times, place side bets, or swap cards between hands. You might also notice changes in how many decks are used, how blackjacks are paid, or what the dealer must do on certain hands. These rule differences are key to understanding the house edge—which is the built-in advantage that the casino has over time.
To help avoid confusion, check the rules inside the game before placing a bet. This can help you understand the key details like potential payout rates and card-handling rules, which can sometimes vary between games—even if they have the same name.
Best Blackjack Variations (Lowest House Edge)
The house edge is the casino’s expected profit from each bet, usually shown as a percentage.
For example, if a game has a house edge of 0.5%, the casino expects to keep 50p out of every £100 wagered over time.
This edge can vary depending on:
Whether you use basic strategy (the mathematically best way to play every hand)
The specific rules of the game
Any mistakes made during play
If you follow optimal basic strategy, you can potentially lower the house edge.
Here are some blackjack versions often found at many UK online casinos with relatively low house edges when played using basic strategy:
Classic Blackjack
Typically uses one or two decks
Dealer stands on 17
Blackjack pays 3:2
House edge: around 0.5%, depending on how you play
European Blackjack
Usually uses two decks
Dealer takes second card after players finish
Blackjack pays 3:2
House edge: approximately 0.5%–0.7%, depending on how you play
Vegas Strip Blackjack
Commonly played with four decks
Dealer stands on all 17s
Players can double after splits
House edge: about 0.35%–0.4%, depending on how you play
Single Deck Blackjack
Played with one deck
Often seen with 3:2 payouts, but many now use 6:5
House edge: around 0.3% (with 3:2 payouts); over 1.5% (with 6:5), depending on how you play
Blackjack Switch
Players manage two hands and can swap top cards
Blackjack usually pays 1:1 instead of 3:2
Dealer 22 often results in a push (not a win)
House edge: roughly 0.6%–0.7%, depending on how you play
Remember, these numbers are based on ideal play. If you ignore basic strategy—such as hitting when it may be safer to stand, or forgetting to double down when it might be favourable—the house edge increases. Even simple errors can raise it to 2% or more, depending on the situation.
To find games with rules that suit your approach, check the in-game information before betting. The rules will explain how blackjacks are paid, what the dealer must do on a soft 17 (a hand that includes an Ace counted as 11), and whether certain strategic options like re-splitting or doubling after a split are available.
Worst Blackjack Variants: Tables To Avoid
Some blackjack games may include rule changes that tend to benefit the casino more than the player. These versions may seem attractive at first, often with extra features or bonuses, but the trade-off is usually a higher house edge.
Blackjack versions with a higher house edge include:
6:5 Blackjack Tables
Instead of the standard 3:2 payout (which gives £15 on a successful £10 bet), these pay 6:5 (£12 on a £10 bet)
House edge increases significantly—often over 1.8%
Super Fun 21
Allows unusual rules like splitting up to four times
Blackjacks often paid at 1:1, not 3:2
House edge: around 1.2% or more
Free Bet Blackjack
Offers “free” double downs and splits
But introduces rules like dealer pushing on 22
House edge: around 1%–1.5%
Multi-Deck Tables With Dealer Hits on Soft 17
Games using six or eight decks where the dealer hits on a soft 17 add to the casino’s advantage
These rules might seem minor, but can push the house edge above 1%
You might still choose to play these versions for their unique features or variety, but it can be helpful to understand how those features can affect your outcomes. A lower payout or a dealer-friendly rule can shift the odds quickly.
Live Blackjack vs Online: Which Is Better?
Live blackjack and online (digital) blackjack each offer a different playing experience, but neither gives you a better chance of winning.
Live Blackjack Played with a real dealer on a video stream. The pace is usually slower, often more social, and there are limited seats. The minimum bets are sometimes higher, and rules vary by table. These games aim to mirror the feel of a physical casino.
Online (Digital) Blackjack Played against software using a Random Number Generator (RNG). These games tend to move quickly and allow you to play on your own schedule. Bets may be smaller, and you may find more rule variations.
Your choice might depend on whether you want a quiet, fast-paced session or a more traditional setup with live interaction. It can be worth reading the rules or help section before you begin, so you understand things like betting limits, available side bets, and payout structure.
