Hey guys.

I'm not a statistician so I thought I would ask here. My local casino has a "Lucky Lucky" side bet on their poker tables that you can make before the cards are dealt. Minimum bet is $1 and max bet is $25. Here is the pay schedule.


Flop Payout
Suited 678 100 to 1
777 50 to 1
Off suit 678 30 to 1
Suited 21 15 to 1
Any 21 3 to 1
Any 20 2 to 1
Any 19 2 to 1
Else lose bet


I don't play this type of stuff but I was curious as to the house edge on the bet. I had a look at the Wizard of Odds site, but I only found a similar lucky lucky side bet for 6-deck blackjack...so I don't think those numbers apply.

Does anyone have any idea of what the house edge is? Thanks.

I have a spreadsheet in google docs. I can't edit it now, but you can save a copy and edit yourself or wait until tomorrow when I can edit it.

Just standard Texas Hold'em in the poker room. It is a sidebet on the table that you can make before the cards are dealt.

I assume the bet is on the three card flop. The Lucky Lucky bet, for blackjack usage, is on the player's card plus the dealer's upcard.

It can wait until tomorrow...no big rush. Thanks for the help!

Correct. It is just the flop cards. The player's hole cards are not involved.

This is their official rule:

"If no flop is placed, all bets will be returned to the players, with the option given to the players to let the bet play for the next hand."

Are aces treated as in blackjack or are they forced to be a constant 1 or 11?



It is in standard blackjack fashion

- Aces count as 1 or 11.
- Face cards count as 10.
- Other cards are their point value.

Let me see if I calculated this right:
Apparently not (which is usually why I confirm my math programmatically) - this is after corrections noted by Miplet
(* indicates any ten-value card)

Suited 678 - 4
One for each suit

777 - 4
One for each suit not in the set

Offsuit 678 - 60
4 (suits for the 6) x 4 (suits for the 7) x 4 (suits for the 8) - 4 (for the four suited 678s)

Suited 21 (besides 678) - 108
KQA, KJA. KTA, QJA, QTA, JTA - 6
*92, *83, *74, *65 - 4 x 4
984, 975, A82, A73, A64 - 5
Total = 4 suits x 27 per suit

There are 24 possibilities for a particular flop that includes a pair
For example, for KKA, there are 6 ways to make the pair of kings (KsKh, KsKc, KsKd, KhKc, KhKd, KcKd), and for each one, four different suits for the ace
If there are three different cards, there are four suits for each card, or 64 ways in all

Offsuit 21 (besides 678 and 777) - 1984
KKA, QQA, JJA, TTA - 4 x 24
KQA, KJA, KTA, QJA, QTA, JTA - 6 x 64 - 6 x 4 (already counted as suited)
*92, *83, *74, *65 - 4 x 4 x 64 - 4 x 4 x 4 (already counted as suited)
993, 966, 885, AA9, A55 - 5 x 24
984, 975, A82, A73, A64 - 5 x 64 - 5 x 4 (already counted as suited)

Offsuit 20 - 1688
*55 - 4 x 24
992, 884, 866, 776, AA8 - 5 x 24
*9A, *82, *73, *64 - 4 x 4 x 64
983, 974, 965, 875, A72, A63, A54 - 7 x 64

Offsuit 19 - 1640
99A, 955, 883, 775, 766, AA7, A44 - 7 x 24
*8A, *72, *63, *54 - 4 x 4 x 64
982, 973, 964, 874, 865, A62, A53 - 7 x 64

Results:
Result Hands Payout Total
Suited 678 4 100 400
777 4 50 200
Offsuit 678 60 30 1800
Suited 21 108 3 324
Offsuit 21 1836 3 5508
20 1688 2 3376
19 1640 2 3280
Other 16760 -1 -16760
Total 22100 - -1872

The house edge is 1872/22100 = 8.471%

You have a few errors:
KKA, QQA, JJA, TTA - 4 x 24 ok
KQA, KJA, KTA, QJA, QTA, JTA - 6 x 64 its over by 24 suited
*92, *83, *74, *65 - 4 x 4 x 64 its over by 64 suited
993, 966, 885, AA9 - 4 x 24 ok
984, 975, A82, A73, A64, A55 - 6 x 64 it over by 20 suited and A55 is a pair so its over by 40

Thanks for the catch. The numbers have been corrected (and confirmed programmatically this time).

I agree with a loss of 1872 units per cycle, for a house edge of 36/425 ≈ 8.47%

Seems odd to me that the payout for the rare suited 21 is the same as that of the much more common offsuit 21. Why bother to even have a separate line item in the table? I'd think that something like 10-1 for the suited 21 would make much more sense, and result in a house edge of around 5%

Yeah, but they are two different results with similar likelihood. Why would you create a separate line item for suited 21 with the same payout as unsuited 21, when you could just create a single line item for "any other 21"?

Been done before ... Sort of.

"Pop the Flop" was a three-card-poker-based side bet based on the flop in Texas Hold'em. If memory serves, it was at Red Rock and Imperial Palace in Las Vegas.

Unfortunately, pop flopped.

I don't know because I didn't create it. My point was that they could have similarly just made a single payline called "19 or 20." My guess is there are other paytables where the prizes for the 21s and 19 & 20 are different, since it is unusual to only create one paytable for a side bet.

Ah crap....I made a mistake when I was putting the table together on my original post. The suited 21 actually pays 15-1 instead of 3-1. I've gone back and fixed my original post. Sorry folks for the mix-up.

What would be the revised house edge....around 2.6% if I've followed the calculations right?

It is at a native charity casino near Port Perry Ontario, Canada. I've included a link to their website outlining the game itself.
