Under-The-Gun 31
Under-The-Gun 31 is a game developed and marketed by a pair of brothers who work at my local San Diego casinos. The game was on the floor at Viejas for a year, and it had a test placement at Pala too. The game is something of a cross between Blackjack and Three Card Poker. They designed the Ante bet with a small house advantage, while they pay good odds for the optional Bonus bet. The idea of the game is to make a hand total as high as possible, where only suited cards add together. Aces are always 11, and face cards have a 10 value. Since you can only add cards of the same suit, the maximum hand value is 31. The A-K-Q suited hand is a mini-Royal. The Ante pays a built-in bonus for a straight flush, a 31, or a mini-Royal.
To begin, the player makes an Ante bet. The Bonus bet is optional. The player and dealer both receive 3 cards. The looks at his hand, and decides to either fold, or to play the hand by betting an additional amount equal to the Ante. If the player stays, he also has the option to discard and draw one card. Once the action is complete, the dealer turns up his 3 cards. The dealer automatically takes a hit, and makes a hand from his 3 best cards. The player’s 31 Bonus and Stay-n-Play Bonus pay regardless of the dealer hand. The player’s Ante and Stay-n-Play bet pay even money against the dealer’s hand.
I know the game inventors, and wrote a playable Flash demo for them. They’d love to hear your feedback. Please try it out, and leave a comment about its playabilty, appeal, etc.. They’re working hard to get it out on the floor again. Click on the screenshot below to play:

I played several sessions. Very hard to win. I think the 4th card the dealer gets is a HUGE house edge.
I did better when not betting the bonus. At no time did I ever get ahead.
Would I play this game? NO!
Tried it again tonight. Still did better not betting bonus. I would like to see what the dealers cards are when I fold though.
Keep trying.
Today I did 4 half hour sessions.
Playing bonus I ended up with $525 and $465
Without bonus $875 and $1005. On the $1005 session I folded a LOT of hands with low cards.
Maybe it’s me. Just unlucky. lol
I get a house edge of 2.1% on the ante bet. Does that sound about right?
I don’t know what the house edge is. You can contact the game owners @ danr@utg31.com, and Danny will probably give you the info. The game is no longer on the floor at Viejas or Pala. But you can ask the owners if it’s headed any where else.
John, Ante Bet is 2.12% on this pay table.
