Perks of playing blackjack for free

Practice your strategy

Not sure if you should split, double down or surrender? Playing free blackjack gives you the chance to try different tactics in a variety of different situations and work your on your blackjack strategy, without the worry of having real money on the table.

Try new blackjack variations

Free online blackjack games are ideal if you want to try something a little different from your standard game of 21. You can test the waters on a few variations, with no money lost if you decide it’s not for you.

Play for fun

It goes without saying that you don’t need to gamble real money to enjoy a game of blackjack. With free games, you can just enjoy the challenge of beating the dealer to 21 without the pressure of a real money game.

Blackjack Rules

The lowdown on the rules of free blackjack

It’s important to understand the rules of blackjack, even when you’re playing for free. The rules are the same as when you’re playing real money games, though accepted moves vary between online blackjack variations.

The aim is to beat the dealer to 21 without going bust – that means exceeding the limit of 21!

Blackjack Moves

Stand– You play out the round with your current cards
Hit– You’ll receive another card to add to your hand
Split– Split two matching cards into separate hands
Double Down– Double your bet and receive one more card in your hand.
Surrender– Give up half of your bet and surrender your hand. This move is only available in certain variations.

Blackjack variations often have different rules on when you can split, double-down and surrender!

How to play blackjack online:

  1. Place your bets

    You make your bets before you’ve seen any cards. Of course, these will be with play money credits.
  2. Press deal

    Press deal to receive your cards. Both of your cards will face up so that you can see the value, while the dealer will usually have one up card (face up) and one facing down. However, this can vary depending on which blackjack game you’re playing.
  3. Make your move

    Your move will depend on the value of the cards in your hand. Happy with your hand? Stand with your current cards. If you fancy your chances with another card, you can hit. You can keep hitting until either you hit 21 or go bust. You can also choose to double down after receiving your first two cards, or split depending on your hand.
  4. Compare hands

    How does your hand compare to the dealer’s hand? Even if you didn’t make it to 21, the closest hand wins!

Mobile blackjack

Play blackjack for free, wherever you are

All of the casino sites have mobile-friendly websites, so it’s easy to grab a game of free blackjack when you’re out and about. You’ll be able to play all of your favourite blackjack variations via mobile – all you need is a stable internet connection.

Want to take your mobile blackjack experience to the next level? Many of the top sites have mobile casino apps, which makes for improved gameplay. These apps are tailored for your device, meaning clearer graphics and smoother functionality. Mobile blackjack apps also have the added benefit of push notifications, which means you can receive alerts on all the latest blackjack games.

FAQs

Are free blackjack games fair?

Yes. Playing at a UK licensed casino site guarantees you a fair blackjack experience, whether you’re playing for free or gambling with real money. The UK Gambling Commission monitors licensees to ensure they use random number generators (RNG) to power animated blackjack games, and live blackjack games are held to equally high standards. Here at Compare.bet, we only recommend UK licensed casinos and betting sites, so you know you’re in for a fair game when you choose from our list.
