Hello everyone!

I've played Blackjack more than any other game, and I have noticed three variations (not including games like Free Bet, Super Fun 21, Spanish 21, etc.)
Variation 1: Sometimes surrender is allowed sometimes it isn't
Variation 2: Sometimes you can re-split aces (Minnesota) and sometimes you cannot
Variation 3: Sometimes the dealer hits soft 17 but rarely they do not (I haven't played since it's always much more expensive).

Are there any other existing blackjack rule variations that can be found in North America?
Let's not count California cardroom variants here.
I have heard that there is ENHC in some Canadian casinos.

Those are the big ones. But there is one other, than normally only applies in double or single deck games- doubling after split, or not. Doubling after split is rare in single deck games. Not doubling after split is not the standard in double deck games and almost always means an undesirable game. A shoe game that doesn't allow DAS is an oddity and something to be avoided.

True DAS is an important difference, and I also forgot that "number of decks" could be considered a rule. When I played double deck in Vegas I asked the dealer if I could double after splitting as I sat down on the table. He said "of course you can, wait, let me check... oh wait I guess you can't I didn't know that". Maybe I shouldn't have asked :D But I would hate to play with suboptimal strategy ;)

Where the heck did you go, to the El Cortez? You have to work hard to find a non-DAS game in Vegas!

When you come out to the show, you can hop across the street to Treasure Island. They and the Strat have the only playable low stakes double deck BJ on the Strip. You can usually get a $15 game at TI.

3/2 6/5 and even money on machines, most important rule variations of all.

Double Any vs D9-10-11 or D10-11
No soft doubles (or after doubling a soft, aces count as 1)

And since someone mentioned machines, there are Charlie rules that show up
May the cards fall in your favor.

Is "no soft doubles" ever separate from "D9/D10-D11"?

On my website I have four options in blackjack: "Double everything", "Double Hard 10-11", "Double Hard 9-11" and "Double Any 9-11" (including soft). Does my classification make sense? Maybe I am including a non-existent option.

Do any casinos in North America not let you split up to three times (four hands)?

Do any in-person casinos still use the "Charlie rule"? (not counting Super Fun 21)

Thanks for your help everyone :)

Pit bosses don't like you jumping your bets substantially between hands, like from $25 to $100 to $200 to $400 to $800 to $1,000, even if you lose all those hands in a row, because it's card counting and you'll be ejected. If it's a Martingale, you may get a reprieve.

In a casino that has the Five Card Charlie rule, does it trump a dealer's BJ?

You don't get to draw against a dealer natural in most games.

No Soft Doubles could be separate from D9, but I don't think I've ever seen it. D9 or D10 can either disallow or allow soft hands.

I have seen some single deck and double deck games only allow splitting to two hands.

I think I've only seen the Charlie rule on a live table during a promotion. I see it more commonly on machines.

In the past I remember games in which you were allowed to split pairs22-TT but not allowed to resplit. That is why RS4 is a describer for BJ games, meaning resplit up to 4 hands.

however, I can't say whether any current B&M or online games have a no resplitting rule.
So many better men, a few of them friends, are dead. And a thousand thousand slimy things live on, and so do I.

Even high limit double deck at Caesars Vegas doesn’t allow DAS. This is an anomaly.

Nowadays you may find both DAS and stand 17 together at high limit DD on the Strip.

There are some casinos that don’t offer insurance.
Also there was a casino that if splitting tens they had to be the same like jj or kk .
Also there were some casinos that if you doubled down on soft19 and got a 2 they would only count your total as 11 because you could only double on 9,10,11 so you were counting the soft 19 as a 9 when you doubled. This was in Reno and I’m not sure if it still exists
Happy days are here again

The Longhorn and Big Horn had double after three cards, but I don't know if they've reopened their table games.

Oh yes I sometimes play progressions in that kind of environment. Sometimes I play one kind of progression, other times I play a different kind. Still progressions, right? Nobody can beat the house with progressions!

Sure you can, but you need lucky streaks to come often enough instead of endless losing streaks or go nowhere for hours types of luck.
