The Caesars Entertainment Blog mentions that the xtreme version of 21+3 can be found in the Party Pit at the Paris casino in Las Vegas. I had to chuckle at their sense of humor with this remark,
'We would calculate the odds of hitting these side bets, but being in Vegas isn't about math, it's about having fun. And just never-you-mind that this is the blog of a casino company. Check out the new Ooh La La Party Pit at Paris Las Vegas the next time you’re in the neighborhood.
Hey, it is about the math everywhere, even in the Party Pit!

Written by: Michael Shackleford21+3 Blackjack is a very popular side bets blackjack variation, invented and patented by Derek J. Webb in 2000. The game is a combination of blackjack and three card poker, where your first 2 cards and the dealer’s face up card are used to combine a three card hand. If you are familiar with Perfect Pairs, then you can look at 21+3 as its further development.
It is considered one of the latest additions and therefore it is not offered by most blackjack sites. Nevertheless, there are 3 versions of 21+3 Blackjack available online and we are sure that more to come.
