Blackjack’s appeal lies in its simplicity. At the start of each hand, you are dealt two cards, with one of the dealer’s cards face up. In some variants, the dealer’s second card is dealt only after you've completed your action. You can choose to draw additional cards ('hit') or stick with your current hand ('stand').
If your hand’s final value exceeds the dealer’s without going over 21, you win.
Additional options include 'splitting' pairs of cards and 'doubling down' on certain hands. To improve your decision-making, refer to a blackjack strategy chart that shows the optimal moves for every situation.
Here, our blackjack experts share five essential tips to improve your online blackjack gameplay:
1. Know When to Stand on 12 or 13
New blackjack players often ‘hit’ with a starting hand of 12 or 13, but this can be a mistake if the dealer’s upcard is weak (4, 5, or 6).
Since 10s, Jacks, Queens, and Kings all count as 10, the dealer’s hidden card is more likely to be a 10. For example, if the dealer’s upcard is a 5, their total could be 15, forcing them to draw again and risk busting.
The smarter play is to ‘stand’ on 12 or 13 when the dealer shows 4, 5, or 6. While it won’t win every hand, this strategy improves results over time.
2. Don’t Split Tens
Beginners might see splitting tens as a chance to create two strong hands, but it’s not a smart long-term play.
A hand totalling 20 is already in a strong position. Splitting here introduces unnecessary risk, turning a probable win into two potentially weaker hands with higher chances of losing.
Even if the dealer shows a weak upcard, like a 5 or 6, stick with your 20 - it’s one of the strongest hands in blackjack. Don’t risk a likely win for marginal gains.
3. Double Down on 11
Doubling down is a great way to maximise winnings when the odds are in your favour. It lets you double your bet and take one more card.
The best time to double down is when your starting hand totals 11. There’s a strong chance your next card will be a 10, giving you 21. Even an 8 or 9 leaves you with a strong hand.
Exception: Avoid doubling down when the dealer’s upcard is an ace, as this increases the chance of the dealer having blackjack, negating your advantage.
4. Never Take Insurance
When the dealer’s upcard is an ace, blackjack games offer an insurance bet. This costs half your original wager and refunds you if the dealer has blackjack.
While tempting, insurance is a losing bet in the long run. Statistically, the odds of the dealer having blackjack don’t justify the cost. Simply put, skip insurance - it’s not worth it over time.
5. Bet Within Your Bankroll
Managing your bankroll responsibly is essential for enjoying online blackjack and maintaining sustainable play. Start by setting a clear budget and sticking to it.
For example, if your budget is £100, avoid placing £10 bets - a few bad hands would quickly deplete your balance. As a general rule, we recommend limiting wagers to no more than 5% of your bankroll per hand.
Beginners, however, are advised to start with 1% or less to maximise gameplay, opting for tables with lower minimum bets to make their bankroll last longer.
As your balance grows, consider increasing your bet sizes gradually to aim for bigger wins. But always stay within comfortable limits and resist the temptation to chase losses.
