Online blackjack in Quebec: rules, house edge and the decisions that matter
Online blackjack is the casino table game where your decisions change the result most. The cards are random, but whether you hit, stand, double or split moves the house edge by whole percentage points. This guide covers how an online blackjack hand works, the formats you meet as a Quebec player, what the published return figures mean, and the decisions that cost the most money when they are played by feel.
The strategy figures below are our own calculations for an infinite deck where the dealer stands on all 17s and checks for blackjack before you act. Real shoes of six or eight decks give results within a fraction of a cent of these numbers.
How a hand of online blackjack works
The aim is to finish closer to 21 than the dealer without going over. Loto-Québec's blackjack rules set out the basics that also apply online:
- Aces count as 1 or 11, face cards count as 10, and every other card counts at face value.
- A blackjack is an ace plus a 10-value card on the first two cards. Blackjack against blackjack is a push.
- You may double after your first two cards and receive exactly one more card.
- You may split a pair by adding a bet equal to the first one, up to four hands. Aces may be split only once, and a 21 made on split cards is not a blackjack.
- When the dealer shows an ace, you can take insurance for up to half your bet. It pays 2 to 1 if the dealer has blackjack and loses otherwise.
On the dealer side, the rule in Evolution's live games is that the dealer must draw to 16 and stand on 17 or higher. The dealer has no choices to make, which is why your own play is the only lever you control.
The formats you will see online
Live dealer blackjack. A real dealer deals from a real shoe on camera, and you act through on-screen buttons. Evolution's Blackjack Classic, listed at Canadian operators, takes $10 to $5,000 per hand and offers Bet Behind, which lets you ride on another player's seat. For more on how these studios work, see our live dealer casino guide.
Infinite Blackjack. Every player shares the same starting cards and makes their own decisions afterwards, so there is no seat limit. Limits run from $1 to $5,000. The main rule change is the Six Card Charlie: six cards totalling 21 or less win automatically, even against a dealer 21.
RNG blackjack. A software dealer and a random number generator replace the shoe. Hands take seconds, which matters more than it seems: the house edge is charged on every hand, so faster play costs more per hour at the same edge.
Variants you also find at Quebec casinos. Loto-Québec's land-based casinos run standard blackjack plus Free Bet Blackjack, Double Down Madness, Bahama Bonus Blackjack and Blackjack Switch. In Free Bet Blackjack, a free bet marker covers a double on a hard 9, 10 or 11 and any split except 10-value cards, and in return a dealer total of 22 pushes your hand instead of busting.
What 99.29% really means
Live blackjack tables publish a return to player (RTP). Evolution lists 99.29% for Blackjack Classic and 99.47% for Infinite Blackjack. Turned around, that is a house edge of 0.71% and 0.53%. Put $100 in total bets through Blackjack Classic and the long-run cost is 71 cents.
Two points about that figure:
- It assumes correct play. An RTP for a game with choices is calculated for the best decisions. Standing on every 12, never doubling or taking insurance all push your personal edge well above the published one.
- The blackjack payout matters more than any other rule. Rule sets approved for live blackjack can pay a natural at 3 to 2 or at 6 to 5. A natural arrives on about 4.73% of hands. Cutting its payout from 1.5 to 1.2 times the bet costs about 1.35% of every initial bet, which is roughly double the whole house edge of a good 3 to 2 table. Check the payout printed on the layout before you sit down.
How often the dealer busts
The dealer's upcard tells you most of what you need. These are the chances that the dealer finishes over 21, by upcard, once the dealer has checked for blackjack:
| Dealer upcard | Dealer busts |
|---|---|
| 2 | 35.4% |
| 3 | 37.4% |
| 4 | 39.4% |
| 5 | 41.6% |
| 6 | 42.3% |
| 7 | 26.2% |
| 8 | 24.5% |
| 9 | 22.8% |
| 10 or face card | 23.0% |
| Ace | 16.7% |
The pattern behind basic strategy sits in this table. Against a 4, 5 or 6 the dealer busts about 4 times in 10, so you avoid risking a bust yourself. Against a 7 or higher the dealer usually makes a hand, so standing on a weak total simply waits to lose.
The decisions that cost the most
Each figure below is the average result per $1 of the original bet for each option. A result of minus 0.54 means you lose 54 cents per dollar over the long run with that hand. The best option is in bold.
| Your hand | Dealer shows | Stand | Hit | Double |
|---|---|---|---|---|
| Hard 16 | 10 | -0.540 | -0.540 | -1.08 |
| Hard 16 | 7 | -0.475 | -0.415 | -0.83 |
| Hard 17 | 10 | -0.420 | -0.584 | -1.17 |
| Hard 12 | 2 | -0.293 | -0.253 | -0.51 |
| Hard 12 | 4 | -0.211 | -0.214 | -0.43 |
| Hard 11 | 10 | -0.540 | 0.119 | 0.180 |
| Hard 11 | Ace | -0.667 | 0.143 | 0.109 |
| Hard 10 | 9 | -0.543 | 0.117 | 0.144 |
| Hard 9 | 3 | -0.252 | 0.101 | 0.121 |
| Soft 18 (A-7) | 9 | -0.183 | -0.101 | -0.29 |
| Soft 18 (A-7) | 6 | 0.283 | 0.191 | 0.382 |
What stands out:
- 16 against a 10 is a coin flip between two bad options. Hitting and standing both lose about 54 cents per dollar, with hitting ahead by less than a tenth of a cent. It feels like a big decision but barely matters.
- 16 against a 7 is where standing hurts. Hitting saves 6 cents per dollar, because a dealer 7 busts only about a quarter of the time.
- 12 against a 2 is a hit. Many players stand, but hitting is worth 4 cents per dollar more. Against a 4, standing becomes slightly better.
- Double your 11 against a 10. Doubling earns 18 cents per original dollar against 12 for a plain hit. Against an ace, with the dealer standing on soft 17, a plain hit is better.
- Soft 18 is not a standing hand against a 9. Hitting A-7 against a 9 saves 8 cents per dollar, and against a 6 you should double it.
Splitting 8s. A pair of 8s is a hard 16. Against a 10, standing loses 54 cents per dollar, while splitting cuts the loss to about 49 cents over the two hands. Against a 6, splitting turns a 15 cent loss into a 33 cent gain. Always split 8s, and never split 10s: a 20 already wins most of the time.
Insurance and side bets
Insurance is a separate bet that the dealer's hidden card is a 10-value card. In an infinite deck, that happens 4 times in 13. The bet pays 2 to 1, so the average result is 2 × 4/13 minus 9/13, a loss of about 7.7% of what you stake on insurance. That is more than ten times the edge on the main hand of Blackjack Classic. Even money on your own blackjack is the same insurance bet under another name.
Side bets such as Perfect Pairs, 21+3, Hot 3 and Bust It pay on the first cards or the dealer's result. Their pay tables appear inside the game, and the RTP shown for the main game does not include them. Treat any side bet as a separate game with its own, usually higher, edge.
Playing online blackjack from Quebec
Loto-Québec's online casino, Espacejeux, runs live blackjack tables from 10 a.m. to 3 a.m. To play there you must be 18 or older, live in Quebec and be physically in Quebec, and your identity is verified at registration. Our Espacejeux guide covers deposits, limits and withdrawals, and our page on online gambling law in Quebec explains where offshore sites fit.
At Loto-Québec's land-based casinos, the By-law respecting casino games requires cards to be shuffled so that they are dealt unpredictably (section 7), each table's minimum and maximum bets to be posted and respected (section 9), and the full game rules, including payout odds and the dealer's strategy, to be available near the table (section 11). Our Casino de Montréal guide covers the tables there.
If you play roulette as well, our online roulette guide has the payouts and edges for every bet. Betting progressions do not change any of the numbers above; the Martingale guide shows why.
