Century 21 blackjack

In California, there are some variations of blackjack such as California 22 and Century 21 blackjack. My question is: has anyone seen these variations in any casino OUTSIDE of California?

I'm not familiar with these games, but several years ago, the Imperial Palace had some wierd BJ game that went to 22. I remember the dealer did not have to hit until 17, being able to stop whenever he wanted.

Which Imperial Palace? The one in Las Vegas?

The Vegas IP and Sahara used to have Extreme BJ, but that was many years aog. According to WOO it was in a few Canadian casinos too.

Yes, but it was several years ago. Perhaps 2005.

Looking at WOO, I don't believe the game I'm talking about was Extreme BJ, as I remember 22 not being a bust.
2005 is the year, as I remember playing ties win BJ in Laughlin that same trip, and that game only lasted a few months.
