More wierd rules, what is the BS and house edge?

[dacium]

Hello!

In Australia we have a game usually called X 21 where X is the casino name (usually crown 21, jupiters 21 etc. etc.).

Anyway its essentially blackjack with the Ten cards removed (but the face cards are still in the game). This obviously give the house a big advantage. To make up for this they give you:

-There is no hole card but if the dealer ends up having blackjack you loose only your original bet (this is standard in australia).
-Double on any value at any time (even if you have 3 or more cards)
-After doubling you may 'forfiet', that is you can reclaim the doubled bet and fold your hand, with the house taking your original bet.
-Any hand of 21 (natural or not) wins automatically, even if the dealer ends up having blackjack.
-You can surrender against a A or T (this would be the equivalent of late surrender since you loose if the dealer ends up having a blackjack).
-Only split once, one card to aces.
-The following enhanced payouts apply, as well as blackjack paying 3:2
five card 21 3:2
678 3:2
777 3:2
six card 21 2:1
777 suited 2:1
678 suited 2:1
seven or more card 21 3:1
678 all spades 3:1
777 all spades 3:1
777 all suited with dealer up card of any other 7 pays 100:1 (only if you dont double, and have not split 77s).

I have been told that the house edge is 1.2%. But from the guys calculations he did not take into account the forfiet rule (which is effectively an early surrender after you double).

Haven't seen anything that would cover these rules. I am guessing a basic strategy could get very complicated.

I read about this game in Blackbelt in Blackjack, I believe. I don't think any of the nonstandard "21" games were recommended. I'd just stick to normal blackjack!

Spanish 21 its called in US casinos and its a crappy game. requires a different BS which may be found at Wizardofodds.com and in Snyder's ne Big Book of Bj which I am currently drafting a review. zg

The only nonstandard "21" games I played is"blackjack switch".

The house edge is about 0.98%.

I test it in casino365 can find that its house edge is really better than normal blackjack.

"Spanish 21" used to be a lot more popular in the US than it is today. Still, there are a few casinos that offer it. Wizard's strategy is supposed to allow you to play this game at an advantage but as ZG stated, it is a far cry from the Basic Strategy you are familiar with.

i deal this game literally everyday. if you want to win money stick to blackjack. it is another useless carnival game.

A 0.98% is about double the house edge at normal blackjack, assuming reasonable rules. The only games that have that bad of a house edge would be 6:5 blackjack.

Sp21 BS leaves a far higher house-edge than normal 21 and BS. Sp21 with SP21BS is about 1.2% - similar to 6:5 ans SF21. zg

SP21 is beatable - in fact with a very large advantage. But, the counting strategy is quite complex. A book will be published, probably in a few months.

Are you suggesting that previous analysis by Wizard, Scobolete and others was insufficient? zg

Isn't this a great game to use 2-1 blackjack coupons on? With the liberal rules you have a high advantage since using the coupon negates the even-money blackjack. I've never done it, maybe they don't allow you to use those coupons on that game.

SP21 is a 3:2 game, but YES, SF21 was the best table to use to old LVA 3;1 coupons. zg

Yeah, I was thinking of SF21 not SP21.
