Quick answerBlackjack is the casino game with the best odds for players: on standard rules (3:2 blackjack payout, dealer stands on soft 17, six or eight decks), basic strategy brings the house edge down to about 0.5%, an RTP of roughly 99.5%. The aim is to beat the dealer's hand without going over 21. Online you can play RNG blackjack from about C$0.50 a hand with free demos, or live blackjack with a real dealer. Avoid tables that pay 6:5 for blackjack: they add about 1.4% to the house edge. In Ontario and Alberta, play for real money at registered sites only.

Blackjack rules
- You and the dealer get two cards. Number cards count face value, J/Q/K count 10, and an ace counts 1 or 11.
- Blackjack is an ace plus a 10-value card on the first two cards. It pays 3:2 (6:5 at some tables).
- Your options: hit (take a card), stand (keep your hand), double (double the bet for one card), split (split a pair into two hands) and sometimes surrender (give up half the bet).
- Bust: over 21 loses immediately, even if the dealer later busts too.
- The dealer plays last by fixed rules: hit to 16, stand on 17 (on most tables, including soft 17).
- Insurance is offered when the dealer shows an ace; it pays 2:1 if the dealer has blackjack.
Blackjack basic strategy chart
For multi-deck blackjack where the dealer stands on soft 17 and doubling after splitting is allowed (the most common online rules). "Dealer" is the dealer's up-card.
Hard totals
| Your hand | Dealer 2–3 | Dealer 4–6 | Dealer 7–9 | Dealer 10–A |
|---|
| 8 or less | Hit | Hit | Hit | Hit |
| 9 | Hit (double vs 3) | Double | Hit | Hit |
| 10 | Double | Double | Double | Hit |
| 11 | Double | Double | Double | Double vs 10, hit vs A |
| 12 | Hit | Stand | Hit | Hit |
| 13–16 | Stand | Stand | Hit | Hit |
| 17+ | Stand | Stand | Stand | Stand |
Soft totals (hands with an ace counted as 11)
| Your hand | Dealer 2 | Dealer 3–4 | Dealer 5–6 | Dealer 7–8 | Dealer 9–A |
|---|
| A,2 / A,3 | Hit | Hit | Double | Hit | Hit |
| A,4 / A,5 | Hit | Hit (double vs 4) | Double | Hit | Hit |
| A,6 | Hit | Double | Double | Hit | Hit |
| A,7 | Stand | Double | Double | Stand | Hit |
| A,8 / A,9 | Stand | Stand | Stand | Stand | Stand |
Pairs
- Always split aces and 8s.
- Never split 10s or 5s (play 5,5 as a hard 10).
- 9,9: split against 2–6 and 8–9; stand against 7, 10 and ace.
- 7,7: split against 2–7, otherwise hit.
- 6,6: split against 2–6, otherwise hit.
- 4,4: split against 5–6, otherwise hit.
- 2,2 and 3,3: split against 2–7, otherwise hit.
Never take insurance. It is a side bet on the dealer's hole card with a house edge of about 7%.
Blackjack odds and house edge
With perfect basic strategy, the rules decide the house edge:
| Rule | Effect on house edge |
|---|
| Blackjack pays 6:5 instead of 3:2 | +1.4% |
| Dealer hits soft 17 | +0.2% |
| No doubling after split | +0.14% |
| Single deck instead of eight | −0.5% (approx.) |
| Late surrender allowed | −0.08% |
A table with 3:2, dealer stands on soft 17, doubling after split and late surrender is close to the best you will find online. Mistakes matter more than rules: playing by feel typically costs 1–2% more.
Blackjack variants online
- Classic / European blackjack: the dealer takes the hole card after players act; check whether you lose doubled bets to a dealer blackjack.
- Atlantic City and Vegas Strip: eight or four decks, late surrender in Atlantic City.
- Single Deck Blackjack: lower edge if blackjack pays 3:2.
- Blackjack Switch: switch cards between two hands, but blackjack pays 1:1 and dealer 22 pushes.
- Free Bet and Power Blackjack: free doubles or power doubles, with rule changes that offset them.
- Multi-hand blackjack: play up to five hands at once.
Read each table's rules before you play; the name alone does not tell you the payouts.
Can you count cards online?
Not in RNG blackjack: the deck is shuffled after every hand. In live blackjack, shoes are long and reshuffled well before the end, and Infinite tables play one hand for everyone, which makes counting impractical. Basic strategy is the most valuable skill online.
Blackjack betting systems
Martingale (double after a loss), Paroli (double after a win) and 1-3-2-6 change the shape of your results but not the house edge. Martingale in particular fails on a run of losses, which in blackjack happens more often than most players expect. Flat betting with basic strategy is the most cost-effective approach.
RNG blackjack vs live blackjack
| RNG blackjack | Live blackjack |
|---|
| Shuffle | Every hand | Shoe, reshuffled periodically |
| Minimum bet | Often C$0.50–C$1 | Usually C$1–C$5 |
| Demo | Usually | Rarely |
| Speed | As fast as you play | 50–70 hands an hour |
Practise basic strategy in RNG demo mode, then try live blackjack for the real-table feel.
Is online blackjack legal in Canada?
Yes. In Ontario and Alberta, play at registered sites; elsewhere, provincial sites (PlayNow, Loto-Québec, ALC.ca, PlayNow SK) and licensed offshore casinos offer blackjack. See casinos by province.
Blackjack and bonuses
Most bonuses count blackjack at 0–10% toward wagering, or exclude it, because its low house edge makes bonuses too easy to clear. Read the terms; see wagering requirements. Cashback bonuses are often better value for blackjack players.
Blackjack on mobile
Online blackjack works well on phones in portrait mode. Many RNG games show a hint button based on basic strategy. See casino apps.
Blackjack glossary
- Hard hand: no ace, or an ace counted as 1.
- Soft hand: an ace counted as 11.
- Up-card: the dealer's face-up card.
- Push: a tie; your bet is returned.
- Surrender: giving up half your bet to end the hand.
How to play online blackjack step by step
- Choose a table and check its rules panel: blackjack payout (3:2), dealer soft 17 rule, number of decks, doubling and splitting rules.
- Place your bet with the chip selector; side bets are optional.
- Read your hand and the dealer's up-card, then look up the move in the chart above.
- Act: hit, stand, double or split. Doubles and splits need an extra stake equal to your bet.
- The dealer completes their hand and the game settles bets automatically.
Start in demo mode with the strategy chart open until the decisions feel automatic.
Why the dealer has the edge
The dealer's advantage comes from one rule: you act first. If you bust, you lose even if the dealer busts afterwards. Basic strategy claws back most of that advantage through doubling, splitting and standing on stiff hands against weak dealer cards, but not all of it. That is why the best blackjack is still about 0.5% in the house's favour.
Blackjack side bets
| Side bet | Wins when | Typical house edge |
|---|
| Perfect Pairs | Your first two cards are a pair | About 4–6% |
| 21+3 | Your two cards plus the dealer's up-card make a poker hand | About 3–4% |
| Insurance | The dealer has blackjack | About 7% |
They are entertainment bets: the main game with basic strategy is far better value.
Blackjack vs other table games
| Game | Best RTP | Skill needed |
|---|
| Blackjack | About 99.5% | Basic strategy |
| Video poker (9/6 Jacks or Better) | 99.54% | Hold strategy |
| Baccarat (banker) | 98.94% | None |
| Roulette (French, La Partage) | 98.65% on even-money bets | None |
