Blackjack is the cheapest game in the casino and the easiest one to make expensive. Played with basic strategy on a decent rule set it costs 0.43 percent of what you stake. Change one line in the rules and it costs 1.82, which is worse than a roulette wheel.
That line is the payout for a blackjack. The good version pays 3 to 2, so a ten euro hand returns fifteen. The bad version pays 6 to 5 and returns twelve. Three euros, on a hand that arrives roughly once in every 21, works out at about 1.4 percent of everything you stake. It is the most expensive sentence on a casino table and it is never in the lobby description.
Not one of the casino reviews on this site names a blackjack rule set, because no lobby publishes one. The same thing is true of the roulette wheel. The numbers that decide the price of a table game are the numbers the lobby leaves out.
Every figure below either carries a named source or is arithmetic you can repeat yourself. No casino has paid to appear here or to soften what the table says.
What Each Rule Costs
| Rule | What it does to the edge | Edge after the change |
|---|---|---|
| Blackjack pays 6 to 5 instead of 3 to 2 | +1.39 points | 1.82% |
| Dealer hits soft 17 | +0.22 points | 0.65% |
| No doubling after a split | +0.14 points | 0.57% |
| Doubling allowed only on 9, 10 and 11 | +0.09 points | 0.52% |
| Late surrender offered | −0.08 points | 0.35% |
The baseline is 0.43 percent: eight decks, dealer stands on soft 17, doubling after a split allowed, played with basic strategy. Rule costs from Wizard of Odds, and each row is measured against that baseline on its own.
Read the first row against the other four. Every rule below it moves the price by a fraction of a point. The payout rule moves it by more than three times the entire edge of the good game, which is why it is the only one worth walking away over.
Why 6 to 5 Costs So Much
The arithmetic is short. A blackjack arrives on about 4.7 percent of hands, which is roughly one in 21. On a ten euro bet the good payout returns fifteen euros and the bad one returns twelve, so each blackjack is three euros lighter.
Three euros on one hand in 21 is about fourteen cents per hand played. Against a ten euro stake that is 1.4 percent of your action, which is where the published figure of 1.39 comes from. You are not losing more often. You are being paid less on the hands you were always going to win.
Stack it with a dealer who hits soft 17 and the table runs at 2.04 percent. At that point the cheapest game in the casino has become more expensive than the European roulette wheel in the next room.
Basic Strategy Is Not Optional
The 0.43 percent figure assumes perfect play. Without the chart it is fiction, because every hand has one correct decision and guessing costs you on each of them.
Basic strategy is not a system and it does not beat anything. It is a lookup table derived from the composition of the deck, which tells you the least bad play for every hand against every dealer card. It is published, it is free, and casinos allow it at the table because it still leaves them ahead.
Five rules carry most of the value. Always split aces and eights. Never split tens or fives. Stand on hard 17 or better. Double 11 against anything except an ace. Never take insurance, which runs about 7.5 percent against you and is the worst bet available at a blackjack table.
The full chart, with every one of those decisions priced, sits on the blackjack tips and tricks page, alongside the one button at the table that is never worth pressing.
Card Counting Does Not Travel Online
Counting works when the cards already dealt tell you something about the cards still to come. Software blackjack reshuffles a fresh virtual shoe before every hand, so nothing carries over and the count is always zero.
Live tables are harder to dismiss, but they are built for the same purpose. Continuous shufflers and deep cuts keep the shoe from ever reaching the depth where a count turns profitable. Treat counting as a casino floor technique that did not make the journey to a screen.
Why the Bonus Will Not Let You Play It
Here is the part that ties blackjack to the rest of this site. It is the cheapest game in the lobby, and that is precisely why the bonus terms keep you off it.
Seven of the casinos I review state that table games count nothing at all toward a wagering requirement: National Casino, Spinanga, HellSpin, DragonSlots, BillyBets, SafeCasino and Spinline. Playfina is the only one that gives them any weight, at 5 percent, so twenty euros of blackjack counts as one euro of turnover.
The logic is not hidden. A game that costs the house 0.43 percent is a poor place to send borrowed money, so the terms route you back to the slots. If blackjack is what you came for, decline the bonus and keep your balance withdrawable. The full version of that sum is on the page about whether to take the bonus at all.
Where Blackjack Runs Live
Nine of the casinos I review list live blackjack in the lobby: Nomini, 22Casino, 1Bet, Playfina, Asino, BetLabel, StoneVegas, AzurSlot and WinRolla. A live table has one advantage that matters here. The rules are printed on the felt, so the payout and the soft 17 rule are visible before you sit down.
With software tables you usually have to open the game and read the paytable or the information panel. It takes thirty seconds and it is worth more than any tip on this page.
How I Checked These Numbers
The rule costs come from Wizard of Odds, measured against a stated baseline of eight decks with the dealer standing on soft 17 and doubling allowed after a split. The 6 to 5 derivation in this page is my own arithmetic from the frequency of a blackjack, and it lands within a rounding error of the published figure.
The casino facts are a different kind of number. Each comes from a full review on this site, read out of the operator’s own terms, and each review carries the date it was last read. Where a casino publishes no rule set, this page says so rather than guessing one.

Blackjack rules belong to the casino, not to the table, and those rules move the edge more than any decision you make. The operators below are ordered by how they scored when I reviewed them.
FAQ About Online Blackjack
Is blackjack really the cheapest game in the casino?
Yes, on a good rule set played with basic strategy, at 0.43 percent. Nothing else on the floor comes close, which you can see on the house edge table for every game.
What does a 6 to 5 blackjack payout cost me?
About 1.39 percentage points, which takes a 0.43 percent game to 1.82. That is worse than European roulette, and it is the single most expensive line in any blackjack rule set.
How do I spot a 6 to 5 table?
It is printed on the felt, usually near the dealer position, and almost never in the lobby description. If you cannot see 3 to 2 written anywhere, assume the worse payout and open another table.
What is basic strategy?
A fixed chart of the correct play for every hand against every dealer card, worked out from the arithmetic of the deck. It does not beat the house, it simply stops you paying more than the rule set already charges.
Should I ever take insurance?
No. Insurance is a side bet on the dealer holding blackjack, and it runs about 7.5 percent against you on an eight deck game, which is more expensive than any main bet on the table.
Does card counting work online?
Not in practice. Software tables reshuffle after every hand and live tables use continuous shufflers or deep cuts, so the count never gets far enough from zero to be worth anything.
Can I clear a bonus by playing blackjack?
Almost never. Seven of the casinos I review count table games as nothing toward wagering, and the one exception counts them at 5 percent. The bonus arithmetic shows what that does to the price.
Is live dealer blackjack better than the software version?
Neither is fairer, because both deal the same odds under the same rules. A live table does show the rules printed on the felt, which is more than most lobby descriptions manage.
How many decks should I look for?
Fewer is better, but the difference between six and eight decks is small next to the payout rule. Check the blackjack payout first, the dealer soft 17 rule second, and the deck count last.
How often are these figures checked?
The rule costs come from a named source and the arithmetic behind them does not expire. The casino facts beside them come from reviews that each carry their own last read date in the review index.
Who Wrote This
I came to this from finance, which is probably why I read a table the way I read a term sheet. Blackjack is the clearest case on the whole floor. The headline is excellent, the price lives in one line of the rules, and that line is the one nobody puts on the tile.
I am responsible for everything published here. Every figure on this page is either arithmetic you can repeat yourself or a number with a named source beside it. If you find one that no longer holds, write to me.
