Version 1
Version 1 of 21+3 I noticed at the Las Vegas Hilton in April, 2001. The side bet pays based on the player's first two cards and the dealer's up card. If the three cards equal a flush, straight, straight flush, or three of a kind the side bet pays 9 to 1. The following table shows the probability of each hand in a six-deck game,as played at the Hilton.
The game is sometimes referred to as 21, as players will try to get a hand total that is equal to 21. The game is not a competitive game in that players do not compete against each other. It is only played between the player and the dealer at the blackjack table. To start learning optimal blackjack strategy, you should strictly follow the plays outlined in our blackjack charts.

- Play four hands across four lanes at the same time, creating as many 21s as you can before time runs out. Play fast, but try not to go over 21 in any lane if you don't have to! Standard blackjack rules apply for each lane. Face cards are worth ten points each, and aces are high and low.

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.
