What are the rules to “22”?

I heard about a game like 21 that’s being played in some Indian gaming casinos called 22.

The concept is fascinating that a new game could be created by a simple change, like the target score.

Is it really just the one rule that changed?
Has it changed the odds in favor of the house, like the addition of 00 did for roulette?
Is the idea to make everyone play to look for a new card-counting system?

well, no, i don’t know anything about it, but one thing it does is eliminate “blackjacks” right off the bat.
There are only 6 card combinations that make 22.
There 16 that make up 21, so that reduces the probability of the house paying an automatic 1.5 times bet. So it seems the house saves a lot of money there.
However, this would probably also eliminate a lot of money the house would be making on insurance, cuz who the hell would buy on an ace up in dealer?

But this is assuming the rules aren’t different. So I’ll wait until further info comes in…

(Warning: Yes, my above probabilities are based on one-decks games, and casinos pretty much all use at least four decks. The number of combos change, but the base probability stays more-or-less the same.)

So called “California Blackjack”:

Note that those two descriptions don’t quite agree - there are apparently several variants in existence. The common features are a goal of 22, a “no bust” rule and some gimmick to make 22 more likely, such as the extra aces in the deck or counting deuces as 2 or 12. It also lacks a house dealer, which is apparently the reason the game came into existence - house banked games were illegal under California gambling laws, except at Indian casinos.
