Re: Double Deck Poker Hypothetical Obviously we get that the rules for the 5 best 5 card hand are standard. What the OP is asking and obviously all the posters have missed is what is the best for action. Poker traditionally has to be played with one deck. When you have more than one deck, the entire face of the game changes - more hands become possible, the probability of some hands changes drastically, and so on. To demonstrate this, I decided to analyze poker with two decks of cards. As I calculate it, this is the correct ranking of hands.

One of the most exciting Blackjack games, Double Deck Blackjack games are available at PokerStars Casino in both Single Player and Multi-Player modes. In poker, players form sets of five playing cards, called hands, according to the rules of the game. Each hand has a rank, which is compared against the ranks of other hands participating in the showdown to decide who wins the pot. In high games, like Texas hold 'em and seven-card stud, the highest-ranking hands win. Poker Hand Probabilities. Mark Brader has provided the following tables of probabilities of the various five-card poker hands when five cards are dealt from a single 52-card deck, and also when using multiple decks. The traditional hand types are described on the poker hand ranking page. These include one hand that belongs to two types at once.

Poker traditionally has to be played with one deck. When you have more than one deck, the entire face of the game changes - more hands become possible, the probability of some hands changes drastically, and so on.
To demonstrate this, I decided to analyze poker with two decks of cards. As I calculate it, this is the correct ranking of hands:
Royal flush
Five of a kind
Straight flush
Flush with two pair
Four of a kind
Flush with one pair
Flush with no pairs (1)
Full house
Unflushed straight
Three of a kind
Two pair
One pair
High card
Note 1: You could, if you liked, join a flush with one pair and a flush with no pairs. Then, a full house would beat them. Flush with two pair is rare enough that it should stay separate, though.
All ties are handled in the same way they would be in normal poker.
Some notes:

• I tried to stick to the framework of basic poker hands as best I could. Because of this, five of a kind and flushes with pairs seemed like necessary additions. You could add all kinds of other spiffy hands if you wanted to (i.e. does having a suited pair make it better?), but that's beyond the point of my analysis.
• The Royal flush being top dog seemed like something players would expect, so I included it. If you preferred, you could consider the Royal to be a straight flush, with five of a kind being better. As long as the Royal flush is considered separately, however, it wins: there are 128 Royals and only 728 fives-of-a-kind.
• With five decks, the Royal flush gets dethroned as the best hand, because a flushed five of a kind (with only 52 possibilities) would be king. I'm not sure how adding more decks would affect this, however.

For the curious (and peer review), here are my actual calculations for each hand. 'C' means combinations, e.g. 8C3 is the number of combinations for drawing 3 items out of a list of 8, derived from the formula nCr = n! / ( (n-r)! * r! )
Edit: I forgot to account for flushed vs. unflushed pairs. Embarrassing! The new numbers are correct.

I'll say! This reminds me of some of the stuff that floats around the internet. It's entertaining, but always leaves me thinking 'Somebody has a lot of free time.'

i.e. does having a suited pair make it better?

Yes.
It's no different than the suited five of a kind in five deck poker that you mentioned.
Similarly, many Black Jack side bets pay X for specific cards, but pay more if they are suited.

Well, the flushed five of a kind is a special case: it's a flush, and it's five of a kind. Same with a straight flush (or for that matter, a Royal) in normal poker. You certainly could say that suited pairs are better, but keep in mind that there's a difference between, say, a suited pair of aces, and a flush with a pair of aces.

I didn't check all of your figures, but I disagree with your Two Pair / Three of a Kind result:

Three of a Kind
trips ..... combin(13,1)*combin(8,3) = 728
kickers ... combin(12,2)*combin(8,1)*combin(8,1) = 4224
total ..... 728 * 4224 = 3,075,072 (this agrees with your total)
Two Pair
pairs .... combin(13,2)*combin(8,2)*combin(8,2) = 61152
kicker ... combin(11,1)*combin(8,1) = 88
total .... 61152 * 88 = 5,381,376 (this is much higher than your total)

The above Two Pair figure does not subtract the counts for suited Two Pair hands if they are deemed to be higher in rank than other Two Pair hands. Nevertheless, the figures show that Three of a Kind is still a better-ranking hand than Two Pair.

Yeah, that looks right. I'm not sure where my mistake was, but it seems to be in punching numbers into my calculator. How I made the exact same mistake more than once is a bit weird, but whatever. I'll change it.

I think you missed the last factor of 8, which corresponds to the suit of the kicker. You listed it, but forgot to include it in the calculation.Wizard

I have a table for poker combinations with 1 to 8 decks here. Scroll down to 'Multi-Deck Probabilities.'

Double Deck Poker Hands Games

The Casino I work at is getting a 6 deck Texas Hold'Em table game next month. 5 of a kind suited is the best hand. It's called Texas Shootout. It's reviewed on the Wizard of Odds site and looks pretty cool.

Here's the Wiz's page on it: http://wizardofodds.com/texasshootout
Looks kinda interesting.
Where do you work?
On a side note: Would that be advertising? Nah. I'd bet that the Wiz wouldn't want you to mention your casino in every post, but since this is tied to the thread's topic, I doubt he'd mind a quick plug.
