My latest video from the 2022 Table Game Protection and Table Games Conference is 21 Stud.
Direct: https://www.youtube.com/watch?v=QDhXo1-w5wQ
This game is blackjack with NO decision making. Your initial two cards are all you get.
In addition:
1. Ace-Ace counts as a blackjack
2. Player wins blackjack ties
3. Dealer wins all other ties
I found the game creator, Brandon Zyxnfryx, to be quite delightful.
The question for the poll is would you play 21 Stud? (multiple votes allowed)

Using an infinite deck approximation, I calculate the House Edge of 21 Stud to be 0.068170977, or 6.817%. I did assume that the BJ (A-A) payout was 1.5 when dealer also has a blackjack.
BTW, is Brandon Zyxnfryx related to Mr. Mxyzptlk?

Oh, I had assumed that A-K was not a blackjack (and thus paid 1-1 and lost to Dealer A-A) because A-A was defined to be a blackjack.
Making that correction, my calculation is now HE = 0.03937541 or -3.9375% However, my calculation is actually a 6-deck calculation in which the dealer hand probabilities are insensitive to the two cards in the players hand.
So, I repeated this calculation based on a 600 deck shoe and I get a House Edge of -0.03930257, which is close enough to confirm your infinite deck result.

Nice game. I would trial it. I'd probably want to find a way to reduce the house edge a tiny bit, but not as low as BJ because you can't misplay hands.
Solid game and play. Easy to learn. Not intimidating for women or new players in general because their play does not affect others. Nice side bet paytable with a possibility to add a progressive for either both cards matchimg or 4 card poker hands.
Well done.

Welcome to the forum, cosmiccow. Its always a good idea for newcomers to take a look at the rules: Forum Rules We look forward to getting to know you!
I think the question of countability is To Be Determined. Yes, a high frequency of getting BJs is in the player's favor, so Aces and (to a lesser extent) Tens should have a positive EOR. But I suspect that excess Tens may also increase the probability of player and dealer tieing on non-BJ hands, and that is where the dealer's advantage comes from. I would normally calculate EORs for the ranks, but I'm about to be very busy for a week, so I imagine some others will do it. This is an easy game to analyze.

Most of my profit in BJ comes from Double Downs, Splits, and Black Jacks. Maybe I cut my losses a bit with surrender too.
Where's the bright points of winning in this game?

That's kind of where I'm at. The lack of player decision makes it approachable, but not enjoyable. I got a chance to play this at the show and I found the side bets to not be engaging enough to make up for no strategy.
It has a place on the casino floor, but it's not something I'd want to play.

And yet you'd give it a trial? Confusing. You even said "solid game and play." Would you like to elaborate on your genuine thoughts, cause otherwise the discussion is going to be really hard to follow.
I agree, I don't think it does. But others certainly seem to, given it placed 2nd in the competition. And I'll concede to the masses' experience. May just not be a game for me.

Nobody needs that kind of HA from a purported BJ game variant. Not even the 6:5 players, but there's too many bettors out there who don't know the difference and it seems like this game was made for greedy casino executives to stiff the customers. Once it catches on, there will be no stopping it, lol.

Saying this game was not ready for casino floors was a mistake. I thought I was posting in the Rule Out game thread.
This game is ready. And adding a Progressive would be even better.
Sorry about the confusion. Totally my fault.

Yes I would love to see someone do the math on this for counting. This game has a pretty high house advantage compared to typical BJ(with decent rules) and counting only gives you a marginal edge (typically 1-2%, which is less than the house advantage here). You are definitely correct as well about how in BJ when the counts get high your chances of a tie go up due to the ratio of 10s left in the deck and in this game you lose with a tie unfortunately, interestingly enough if you tie with a BJ you win the full 1.5 payout though! Maybe a system that weights A's higher would be better or the side bets are more countable than the main game with the match the dealer or player bets.
As a side note this game really seems like if BJ and baccarat had a baby!

It looks as if the things to count are the Aces as the removal of one has quite an effect!
I think adding Aces (c.f. Californian BJ) would make the game very interesting. Single Deck HE=-3.547 450%, add 4 extra Aces HE=-0.022598. Six decks HE would go to -0.155 953%.
EOR - remove one card from the shoe
10=T,J,Q,K.

I agree. This is a boring no-fun game with a house advantage that is unattractively high.
What's next?
High Card Hijinx
The dealer and player each get dealt one card. There are no decisions.
- Highest card wins. A>K>Q>J>10
- A win by player with an ace pays 1.5.
- A Tie is considered a win for the dealer and a loss for player.
Big whoop. I just invented an ugly boring game with a high HA similar to 21 Stud. But it can be dealt quickly and is easy to explain.

Interestingly your rules with winning Ace paying 2/1 (but tie losing) would be 0.59% infinite deck and only goes into the Player's advantage with 3 decks or fewer.

Yeah, I conceived of this game as a satire on 21 Stud. When I did the odds in my head, I didn't have exact numbers but I was surprised how similar the HA was to 21 Stud. Your variations are interesting and make sense, but at its core this is a game with no decisions and I imagine it wouldn't be much fun.

@ZCore13 I am flattered by your positive reception of the game.
As the creator, my goal is to provide a frictionless "21' experience for women, new players, or action junkies that prefer Bonuses.
I'm looking at a California installation this January at the Eagle Mountain Casino, with an active footprint in the NH Gaming market.
The opinions of the game are polarized (love or hate) but the majority of people that have taken a chance to play for real money.
I can send you more performance data, and we can discuss further!
4 card progressive opportunities have also been discussed with Galaxy Gaming, specifically their Monster Match PJP product.
Obviously, any 4-card evaluation would work, giving this a "full meal" experience for the consumer.
Thank you again to the Wizard for making this information available to everyone.
I believe the Casino Patron is entitled to the choice of "hit' or "no hit" versions of 21 games. My two cents~
As far as hands per hour, you can deal a full table under 1 minute.
That's 24 bet resolutions assuming all spots are played!

Hey @ChumpChange!
When playing 21STUD, you will enjoy being paid Blackjack on ANY combination of 21 or 22 (Aces).
In terms of Bonus Bets, when a Player is playing all positions, you are hoping to be dealt a pair of Suited Aces for a payout of 40 to 1 (30 to 1, if Spanish rules)
During a typical game, the Player will naturally gravitate towards all 4 betting positions.
At which point the game becomes "please deal me a suited pair" for a 25x minimum payout, with the potential of the dealer flipping another match for either 1 or possibly 2 repeat pays at 18 to 1.
Generally speaking, I've found that most Players are very accepting of the "No Push" rule.
This works because there is also "No Bust".
I appreciate you taking an interest. Cheers!

Hey @SphinxOfCups -
I'm glad you had a chance to play 21STUD!
I can appreciate that a lack of player-decision may be a turn-off for the more experienced gambler.
Totally get it.
Given this, I believe 21STUD is a best fit for those markets where Casino War thrives, as the game offers similar gameplay with an increase bet velocity overall.
It may also do well in the touristy areas because this is as an "easy game".
Generally speaking, I think the average casino goer is recreational by nature.
Recreational meaning - once or twice a year.
Does anyone know what the industry average is?
By comparison, I go to a theme-park once or twice a year, whereas a casino is more like twice a month for me.
I imagine going to the casino is once or twice a year for the majority of folks.
So in that sense, I'd argue 21STUD is more for them.
Just a few talking points to consider. Nice discussion here!

Thanks for telling me that. I certainly have no pretensions of being a game developer, I think of myself as a game analyst.
To reduce the game one step further, you could simply deal a single card. If its 9 - A, player wins; when its 2-8 dealer wins. With Ace the player gets paid 1.5 to 1.
This one might be countable! LOL.
