Blackjack
Blackjack is one of the best-known card games in online casinos. Your goal is to get closer to 21 than the dealer without going over. Online, blackjack is offered either via a Random Number Generator (RNG) or in live-dealer studios with a real shoe.

Overview
- You play against the dealer, not other players.
- Cards 2–10 count their face value, face cards 10, the ace 1 or 11.
- A blackjack is an ace plus a 10 or face card and usually pays 3:2.
- Online versions differ mainly in dealer rules, payouts and side bets.
Rules
- You receive two face-up cards; the dealer gets one face-up and one face-down (except in European variants).
- Possible actions: Hit, Stand, Double Down, Split, sometimes Surrender.
- Going over 21 = bust and immediate loss.
- The dealer draws to 17 (Stand on 17) or hits soft 17 depending on the table.
How to play
- Pick a table with clear limits and a 3:2 payout, not 6:5.
- Read the table rules (S17/H17, double rules, surrender).
- Play strict basic strategy, not gut feeling.
- Set a session budget and stick to it.
Tips & Strategy
- Memorize the basic-strategy chart for the exact variant you play.
- Always decline insurance — mathematically a losing bet.
- Always split aces and eights, never tens or fives.
- Avoid side bets like Perfect Pairs or 21+3 — they carry a high house edge.
Common mistakes
- Playing 6:5 tables instead of 3:2.
- Standing on 16 versus a dealer 7.
- Taking insurance against an ace.
- Chasing losses with bigger bets (Martingale).
Odds & Probability
Blackjack has one of the lowest house edges in the casino — but only if you play a 3:2 variant with basic strategy.
FAQ
+Does card counting work online?
Not in RNG blackjack, since the deck is reshuffled after every hand. In live-dealer games with a shoe it's theoretically possible but practically unprofitable due to deep cuts and fast play.
+What's the difference between RNG and live blackjack?
RNG uses an audited random number generator and is instantly playable. Live blackjack is streamed from a studio with a real dealer.
+Which variant is mathematically best?
Classic single-deck or European blackjack with S17 and 3:2 payout — when available.
Blackjack variants
Online casinos offer many blackjack variants with significantly different house edges. The most important:
Classic Blackjack
The timeless standard with the lowest house edge.
Classic Blackjack is the standard variant in almost every online casino. Played with 1–8 decks, dealer stands on all 17s, blackjack pays 3:2.

No hole card — slightly different strategy.
In European Blackjack the dealer only takes a second card after all players have acted. This subtly changes basic strategy in some spots.
Learn more →Live Blackjack
Real dealer, real cards, streamed via video.
Live Blackjack is streamed from a studio with a real dealer and physical cards. Providers like Evolution, Pragmatic Live or Playtech run dozens of tables 24/7.
Learn more →Multi-Hand Blackjack
Play 2 to 5 hands at once.
Multi-Hand lets you play several boxes per round. It speeds up the game and can be useful, but doesn't change the per-hand house edge.

Swap the top cards between your two hands.
In Blackjack Switch you always play two hands and can swap the second card between them. In return, dealer 22 is a push against all non-busted player hands.
