Online blackjack brings the classic casino card game to your screen, allowing players to compete against the dealer in real-time. Played with one or more decks, the objective is simple: beat the dealer by getting a hand value closest to 21 without going over.

UK players love online blackjack for its fast-paced action, low house edge, and variety of game variants like Classic Blackjack, European Blackjack, and Multi-hand Blackjack. Licensed sites ensure fair play with RNG technology or live dealers.

With stakes from pennies to high rollers, online blackjack suits every budget and skill level.

Blackjack rules are straightforward yet strategic. Each player receives two cards face up, while the dealer gets one up and one down. Card values are: numbered cards as face value, face cards 10, and Aces 1 or 11.

Options include Hit (take another card), Stand (keep current hand), Double Down (double bet for one more card), Split (if pair, play two hands), or Surrender (forfeit half bet in some games).

• Blackjack pays 3:2 (Ace + 10-value card).
• Dealer hits on soft 17 in most variants.
• Insurance available if dealer shows Ace.

Understanding these rules gives players an edge from the start.

Basic strategy is a mathematically proven chart dictating the optimal play for every hand against the dealer's upcard. It reduces the house edge to under 0.5%, maximising long-term wins.

Key moves: Always split Aces and 8s; never split 10s or 5s; double down on 11 vs dealer 2-10; stand on hard 17+.

Free basic strategy charts are available on Blackjack4.co.uk for quick reference. Practice in free play mode to internalise it.

UK casinos often allow strategy use, making it essential for serious players.

Card counting tracks high vs low cards remaining to adjust bets. Popular systems like Hi-Lo assign +1 to low cards (2-6), 0 to 7-9, -1 to 10-Ace.

Increase bets when count is positive (fewer low cards left). While effective in live games, online RNG shuffles make it challenging, but live dealer streams allow it.

Practice with simulators. Note: Casinos may ban counters, so use discreetly.
