Our poker parlor has a jackpot for a royal flush holding 2 of the five cards needed. As many times it is hit, these odds have to be wrong. I could go in to a lot of detail about no. on hands deal daily , but it is pointless. We hit jackpot 8 to 13 times a month. The formula does not compute for the no. of hits, no even close. Looking @ another thread the odds are for a 5 card draw game. NOT holdem. Odds more like 32000. to 1 Last edited by naplesplayer; 10-22-2008 at 09:36 AM. |

I think it should be 4 * C(47,2) / C(52,7) = 1/30940. That is to say, you have 4 5-card Royals and then C(47,2) ways to distribute the other 2 cards in your 7 card board. Then divide by the total number of possible 7-card boards. Correct? |

| 10-22-2008, 05:24 PM | # 7 | | jay_shark Pooh-Bah Join Date: Sep 2006 Posts: 3,655 | Re: Odds on Royal flush My solution computes the probability that you hit a royal flush by the river using both of your hole cards. Your solution computes the probability that you hit a royal flush even if you were dealt a hand such as 7-2o, and then you chopped the pot by hitting a royal flush. Or that you were dealt a hand such as Ah Kh and then the board came 10sJsQsKsAs,etc |

Obviously if you see raise, RR, shove, then you need to fold AJ suited. |

| 04-16-2012, 03:22 AM | # 19 | | fruktpuff stranger Join Date: Sep 2011 Posts: 1 | Re: Odds on Royal flush The likelyhood of getting paid off with a royal flush in PLO is way lower though, the only chance you have of it happening is on a paired board by a full house really. No one is going to pay with 6th flush, or with a straight when the flush has come in, really. |

Pardon bumping an old thread. If this information is correct, and it looks to be correct, would a 2-card-in-hand royal flush show up 1 in ~6.5k hands at a 10-handed table? Obviously some assumption is being made that every suited broadway hand enters the pot and plays to the river. Just trying to find some facts in a world of mis-information |

Yes, since only 1 player can have a royal with 2 cards in his hand, the players having a royal represent mutually exclusive events, so the probabilities add, and the probability for 10 players is exactly 10 times that for 1 player. The other numbers are correct too. Happy Mutually Exclusive Day. Quote: | Just trying to find some facts in a world of mis-information |
That should be the subtitle of this forum. |

| 09-12-2015, 11:28 AM | # 25 | | Wave Function stranger Join Date: Jun 2014 Posts: 5 | Re: Odds on Royal flush A guy at my table the other day flopped a royal flush. I believe the odds are in the neighborhood of 650,000 to 1 and making one by the river is something like 65,000 to 1. He got payed 0 of his own money back that was pumped into the promo fund. This is just ludicrous and insulting. Oh and BTW this guy who is a semi reg, did not know about the promotion. I really hope the new manager gets back to the basics regarding marketing of what could be a top poker room in the Country. Whatever route he decides to go promotion wise, this information needs to be communicated to the players and casual casino patrons. Doing things like listing the BBJ on billboards in and out of the casino, requiring poker room hosts to actively direct players to a clear and concise poster of the promotions so they are informed (Bravo is nice, but many players have no idea what it is). I personally would love to see the BBJ grow quicker and money funneled into reserves so it does not reset at a comical number. At certain levels the hand requirements should be reduced like many rooms do. Quad 10's or better has to be the hardest BBJ to hit in the Country. I would also love to see progressive royal flush payouts. Its a nice promotion that builds excitement and does not neglect the weekend player. Lastly please bring back 'Poker Plinko' I can think of no better poker room promo......just kidding. Good luck to the new manager and I hope that upper management allows him to do his job. |
