How to play three card poker
The important elements of creating great casino poker games are to firstly make the rules easy to understand, and secondly, the payouts have to be appealing to players. Derek Webb, the game’s inventor, combines these factors to a tee. Learning the basics of how to play three card poker only takes a minute or two.
Of course, you want to refine your play with a proven strategy, but we’ll get to that part later. For now, let’s explain 3 card poker rules and guide you through the gameplay.
Three card poker rules
Once you know the rules, you’ll be well on your way to being able to play 3 card poker online. The game is played with a standard 52-card deck. Here’s a step-by-step guide to a single round.
- To begin a round, the player must place an ante bet.
- The dealer then deals three cards to the player, which are face-up, and three cards to himself, which are face down.
- Based on the three cards, the player can either fold the hand or continue by placing a play bet.
- If the player folds, he loses the original ante bet wager.
- If he continues, the cost of the play bet is equal to the ante bet.
- Assuming the player continues, the dealer turns over his three cards.
- The dealer’s hand needs to be at least Queen high to qualify.
- If the dealer’s hand doesn’t qualify, the player wins even money (1:1) on the ante bet, but the play bet is pushed (returned).
- When the dealer does qualify; the player’s hand is compared to the dealer’s hand. The winner is determined according to the order of 3 card poker hand ranks.
- If the player’s hand wins, he gets paid 1:1 on both the ante bet and the play bet.
- If the dealer’s hand wins, both bets are lost.
- It is possible for the hands to tie. In which case, the ante and play bets are pushed.
- Regardless of the outcome of the round, if the player holds a straight or higher, he wins an ante bonus (as described below).
Poker hand ranks
There’s a slight alteration in the poker hand ranks for this game (compared to most other forms of poker). The reason is that you are less likely to hit a straight draw than you are to get a flush draw. This is the ranking order, starting with the highest three card poker hand at the top:
- Straight flush: 3 cards of the same suit in consecutive order.
- Three of a kind: 3 cards of equal face value.
- Straight: 3 cards of mixed suits in consecutive order.
- Flush: 3 cards from the same suit but not in consecutive order.
- Pair: two cards of equal face value.
- High card: none of the above hands, means you only have a high card.
Three card poker odds and payouts
We described the standard 1:1 payouts in the 3 card poker rules outlined above, but those are just one part of this game. The excitement jumps up a few notches because three card poker also includes an ante bet bonus. The ante bet bonus is based purely on the player’s three cards. Therefore, you can win this bet but still lose the round.
Ante bet bonus payouts:
- Straight flush: 5 times the ante bet
- Three of a kind: 4 times the ante bet
- Straight: 1 times the ante bet
Pair Plus bet
Before the start of a hand, players can also make a Pair Plus side bet. Again, this wager is independent of the outcome of your game against the dealer. It’s based on the 3 cards you are dealt.
Pair Plus bet payouts:
- Straight flush: 40 to 1
- Three of a kind: 30 to 1
- Straight: 6 to 1
- Flush: 4 to 1
- A pair: 1 to 1
Six Card bonus
The six card bonus is another optional side bet, but not all three card poker games offer this wager. It uses the three player cards and the three dealer cards from which you must form a five-card hand that is on the pay table to win.
Pair Plus bet payouts:
- Royal flush: 1000 to 1
- Straight flush: 200 to 1
- Four of a kind: 50 to 1
- Full house: 25 to 1
- Flush: 15 to 1
- Straight: 10 to 1
- Three of a kind: 5 to 1
These poker hand rankings are more traditional with a royal flush being the best possible hand, and the flush payout is valued higher than the straight.
3 card poker strategy
We can categorize casino card games into two types. The first are games of chance, such as baccarat and Dragon Tiger. The others are decision-based games like blackjack, Caribbean Stud, and Casino Hold’em. Three card poker drops into the second type because the player makes a decision after seeing his cards on whether he wants to fold or continue by making the play bet.
All of these decision-based games have an optimal strategy. However, some of these involve studying playing charts, which dilutes the entertainment value of the game when you first start playing. The 3 card poker strategy doesn’t bother with such complexities. In fact, you only need to remember 3 cards.
The optimal three card poker strategy for the ante and play bet is QUEEN – SIX – FOUR
This means if your hand is equal to, or stronger than, Q-6-4, you should always raise and make the play bet. What you need to remember is to look at each card separately.
- Start with your highest card. If it’s lower than a Queen – you fold the hand.
- If the highest card is a King or Ace – you raise.
- If the highest card is a Queen, you must look at the second highest card. If lower than 6 – you fold the hand. But, if higher than 6 – you raise.
- If the second highest card is 6, you move onto the third card. Lower than 4 means you fold. 4 or higher, and you raise.
House edge
When choosing what casino games to play, you should always consider the house edge. This is essentially the advantage the casino has. The good news is the three card poker house edge is competitive, which is why this game has grown in popularity.
- The house edge for the ante and play bet combination is 2.01% when using the Q-6-4 strategy described above.
- For the Pair Plus bet, the house edge is 2.32% based on the pay table used in our example. This is reasonable value for a side bet.
- The same cannot be said for the Six Card Bonus bet. It has a house edge of 14.36% using the pay table shown. Therefore, even though the royal flush pays 1000 to 1, this side bet will cripple your bankroll over the long-term.
New players should note that the term ‘house edge’ is rarely used these days. Instead, the theoretical return to player (RTP) percentage is given. The RTP can be calculated by: 100% – house edge. Therefore, the RTP for the ante – play bet is 97.99%.
Tips for playing 3 card poker
Using our experience, and from talking with other three card poker players, we’ve composed a few easy-to-follow tips to help you get more from this game.
- Follow the Q-6-4 strategy. It can be tempting to play J-10-8 because the cards are all reasonably high, but this is not smart, and you will end up losing more than you win.
- Check the pay tables before you play. Several software developers have created their own variants, and there is also live 3 card poker. Just because the title of the game is the same, it doesn’t mean the pay tables are. This has an impact on the RTP, and you want to play where you get the best value.
- Avoid the Six Card Bonus wager. The RTP for this bet is 85.64%. That means on average (over the long-term) for every $100 wagered, you win $85.64.
- Manage your bankroll. You don’t want to play $20 ante bets, and $20 play bets if you only have $100 in your casino account. Look to divide your budget so you can get 50 to 100 hands out of what you have.
- Practice by playing free three card poker games. Most online casinos, after you have registered, will allow you to play in demo mode. This allows you to practice your playing and betting strategy. Please note, you won’t be able to play live 3 card poker games for free.
Live three card poker
The award-winning Evolution Gaming, in partnership with Scientific Gaming, has created a spectacular live dealer three card poker game. This brings you all the authentic gameplay that you get in a land-based casino, but from the comfort of your own home.
It should be noted that there is usually a trade-off playing live games. Most of the time, the RTP is lower due to the extra costs involved in operating these tables. For instance, we’ve read reports that the ante bonus on Evolution’s live variant pays 5 to 1, but you need a mini royal flush to claim it.
This title also has the two side bets we talked about above. However, the pay table for Pairs Plus is not identical. Playing live, there is a maximum payout of 100 to 1 for a mini royal. This may appear more rewarding, but the payout for a straight is less, so the house edge ends up being higher. With that said, playing three card poker live is a great experience, and we think it’s worth trying even though the RTP is not as high.
Where to play online three card poker

The decision where to play three card poker depends on what you want from the casino. Each operator has its strengths and weaknesses. Some offer larger bonuses, while others have faster payouts or better mobile apps. If you’re looking for your first casino, we recommend checking out our online casino reviews section for an honest point of view. In terms of bonuses specific for 3 card poker; the truth is that there aren’t many. You can use a casino’s welcome bonus to play, but the wagering requirements combined with game weighting limitations means you are unlikely to score a profit from these offers.

This page describes the ranking of poker hands. This applies not only in the game of poker itself, but also in certain other card games such as Chinese Poker, Chicago, Poker Menteur and Pai Gow Poker.
- Low Poker Ranking: A-5, 2-7, A-6
- Hand probabilities and multiple decks - probability tables
Standard Poker Hand Ranking
There are 52 cards in the pack, and the ranking of the individual cards, from high to low, is ace, king, queen, jack, 10, 9, 8, 7, 6, 5, 4, 3, 2. In standard poker - that is to say in the formal casino and tournament game played internationally and the home game as normally played in North America - there is no ranking between the suits for the purpose of comparing hands - so for example the king of hearts and the king of spades are equal. (Note however that suit ranking is sometimes used for other purposes such as allocating seats, deciding who bets first, and allocating the odd chip when splitting a pot that can't be equally divided. See ranking of suits for details.)
A poker hand consists of five cards. The categories of hand, from highest to lowest, are listed below. Any hand in a higher category beats any hand in a lower category (so for example any three of a kind beats any two pairs). Between hands in the same category the rank of the individual cards decides which is better, as described in more detail below.
In games where a player has more than five cards and selects five to form a poker hand, the remaining cards do not play any part in the ranking. Poker ranks are always based on five cards only, and if these cards are equal the hands are equal, irrespective of the ranks of any unused cards.
Some readers may wonder why one would ever need to compare (say) two threes of a kind of equal rank. This obviously cannot arise in basic draw poker, but such comparisons are needed in poker games using shared (community) cards, such as Texas Hold'em, in poker games with wild cards, and in other card games using poker combinations.
1. Straight Flush
If there are no wild cards, this is the highest type of poker hand: five cards of the same suit in sequence - such as J-10-9-8-7. Between two straight flushes, the one containing the higher top card is higher. An ace can be counted as low, so 5-4-3-2-A is a straight flush, but its top card is the five, not the ace, so it is the lowest type of straight flush. The highest type of straight flush, A-K-Q-J-10 of a suit, is known as a Royal Flush. The cards in a straight flush cannot 'turn the corner': 4-3-2-A-K is not valid.
2. Four of a kind
Four cards of the same rank - such as four queens. The fifth card, known as the kicker, can be anything. This combination is sometimes known as 'quads', and in some parts of Europe it is called a 'poker', though this term for it is unknown in English. Between two fours of a kind, the one with the higher set of four cards is higher - so 3-3-3-3-A is beaten by 4-4-4-4-2. If two or more players have four of a kind of the same rank, the rank of the kicker decides. For example in Texas Hold'em with J-J-J-J-9 on the table (available to all players), a player holding K-7 beats a player holding Q-10 since the king beats the queen. If one player holds 8-2 and another holds 6-5 they split the pot, since the 9 kicker makes the best hand for both of them. If one player holds A-2 and another holds A-K they also split the pot because both have an ace kicker.
3. Full House
This combination, sometimes known as a boat, consists of three cards of one rank and two cards of another rank - for example three sevens and two tens (colloquially known as 'sevens full of tens' or 'sevens on tens'). When comparing full houses, the rank of the three cards determines which is higher. For example 9-9-9-4-4 beats 8-8-8-A-A. If the threes of a kind are equal, the rank of the pairs decides.
4. Flush
Five cards of the same suit. When comparing two flushes, the highest card determines which is higher. If the highest cards are equal then the second highest card is compared; if those are equal too, then the third highest card, and so on. For example K-J-9-3-2 beats K-J-7-6-5 because the nine beats the seven.If all five cards are equal, the flushes are equal.
5. Straight
Five cards of mixed suits in sequence - for example Q-J-10-9-8. When comparing two sequences, the one with the higher ranking top card is better. Ace can count high or low in a straight, but not both at once, so A-K-Q-J-10 and 5-4-3-2-A are valid straights, but 2-A-K-Q-J is not. 5-4-3-2-A, known as a wheel, is the lowest kind of straight, the top card being the five.
6. Three of a Kind
Three cards of the same rank plus two unequal cards. This combination is also known as Triplets or Trips. When comparing two threes of a kind the rank of the three equal cards determines which is higher. If the sets of three are of equal rank, then the higher of the two remaining cards in each hand are compared, and if those are equal, the lower odd card is compared.So for example 5-5-5-3-2 beats 4-4-4-K-5, which beats 4-4-4-Q-9, which beats 4-4-4-Q-8.
7. Two Pairs
A pair consists of two cards of equal rank. In a hand with two pairs, the two pairs are of different ranks (otherwise you would have four of a kind), and there is an odd card to make the hand up to five cards. When comparing hands with two pairs, the hand with the highest pair wins, irrespective of the rank of the other cards - so J-J-2-2-4 beats 10-10-9-9-8 because the jacks beat the tens. If the higher pairs are equal, the lower pairs are compared, so that for example 8-8-6-6-3 beats 8-8-5-5-K. Finally, if both pairs are the same, the odd cards are compared, so Q-Q-5-5-8 beats Q-Q-5-5-4.
8. Pair
A hand with two cards of equal rank and three cards which are different from these and from each other. When comparing two such hands, the hand with the higher pair is better - so for example 6-6-4-3-2 beats 5-5-A-K-Q. If the pairs are equal, compare the highest ranking odd cards from each hand; if these are equal compare the second highest odd card, and if these are equal too compare the lowest odd cards. So J-J-A-9-3 beats J-J-A-8-7 because the 9 beats the 8.
9. Nothing
Five cards which do not form any of the combinations listed above. This combination is often called High Card and sometimes No Pair. The cards must all be of different ranks, not consecutive, and contain at least two different suits. When comparing two such hands, the one with the better highest card wins. If the highest cards are equal the second cards are compared; if they are equal too the third cards are compared, and so on. So A-J-9-5-3 beats A-10-9-6-4 because the jack beats the ten.
Hand Ranking in Low Poker
There are several poker variations in which the lowest hand wins: these are sometimes known as Lowball. There are also 'high-low' variants in which the pot is split between the highest and the lowest hand. A low hand with no combination is normally described by naming its highest card - for example 8-6-5-4-2 would be described as '8-down' or '8-low'.
It first sight it might be assumed that in low poker the hands rank in the reverse order to their ranking in normal (high) poker, but this is not quite the case. There are several different ways to rank low hands, depending on how aces are treated and whether straights and flushes are counted.
Ace to Five
This seems to be the most popular system. Straights and flushes do not count, and Aces are always low. The best hand is therefore 5-4-3-2-A, even if the cards are all in one suit. Then comes 6-4-3-2-A, 6-5-3-2-A, 6-5-4-2-A, 6-5-4-3-A, 6-5-4-3-2, 7-4-3-2-A and so on. Note that when comparing hands, the highest card is compared first, just as in standard poker. So for example 6-5-4-3-2 is better than 7-4-3-2-A because the 6 is lower than the 7. The best hand containing a pair is A-A-4-3-2. This version is sometimes called 'California Lowball'.
When this form of low poker is played as part of a high-low split variant, there is sometimes a condition that a hand must be 'eight or better' to qualify to win the low part of the pot. In this case a hand must consist of five unequal cards, all 8 or lower, to qualify for low. The worst such hand is 8-7-6-5-4.
Deuce to Seven
The hands rank in almost the same order as in standard poker, with straights and flushes counting and the lowest hand wins. The difference from normal poker is that Aces are always high , so that A-2-3-4-5 is not a straight, but ranks between K-Q-J-10-8 and A-6-4-3-2. The best hand in this form is 7-5-4-3-2 in mixed suits, hence the name 'deuce to seven'. The next best is 7-6-4-3-2, then 7-6-5-3-2, 7-6-5-4-2, 8-5-4-3-2, 8-6-4-3-2, 8-6-5-3-2, 8-6-5-4-2, 8-6-5-4-3, 8-7-4-3-2, etc. The highest card is always compared first, so for example 8-6-5-4-3 is better than 8-7-4-3-2 even though the latter contains a 2, because the 6 is lower than the 7. The best hand containing a pair is 2-2-5-4-3, but this would be beaten by A-K-Q-J-9 - the worst 'high card' hand. This version is sometimes called 'Kansas City Lowball'.
Ace to Six
Many home poker players play that straights and flushes count, but that aces can be counted as low. In this version 5-4-3-2-A is a bad hand because it is a straight, so the best low hand is 6-4-3-2-A. There are a couple of issues around the treatment of aces in this variant.
- First, what about A-K-Q-J-10? Since aces are low, this should not count as a straight. It is a king-down, and is lower and therefore better than K-Q-J-10-2.
- Second, a pair of aces is the lowest and therefore the best pair, beating a pair of twos.
It is likely that some players would disagree with both the above rulings, preferring to count A-K-Q-J-10 as a straight and in some cases considering A-A to be the highest pair rather than the lowest. It would be wise to check that you agree on these details before playing ace-to-six low poker with unfamiliar opponents.
Selecting from more than five cards
Note that in games where more than five cards are available, the player is free to select whichever cards make the lowest hand. For example a player in Seven Card Stud Hi-Lo 8 or Better whose cards are 10-8-6-6-3-2-A can omit the 10 and one of the 6's to create a qualifying hand for low.
3 Card Poker Game Rules
Poker Hand Ranking with Wild Cards
A wild card card that can be used to substitute for a card that the holder needs to make up a hand. In some variants one or more jokers are added to the pack to act as wild cards. In others, one or more cards of the 52-card pack may be designated as wild - for example all the twos ('deuces wild') or the jacks of hearts and spades ('one-eyed jacks wild', since these are the only two jacks shown in profile in Anglo-American decks).
The most usual rule is that a wild card can be used either
- to represent any card not already present in the hand, or
- to make the special combination of 'five of a kind'.
This approach is not entirely consistent, since five of a kind - five cards of equal rank - must necessarily include one duplicate card, since there are only four suits. The only practical effect of the rule against duplicates is to prevent the formation of a 'double ace flush'. So for example in the hand A-9-8-5-joker, the joker counts as a K, not a second ace, and this hand is therefore beaten by A-K-10-4-3, the 10 beating the 9.
Five of a Kind
When playing with wild cards, five of a kind becomes the highest type of hand, beating a royal flush. Between fives of a kind, the higher beats the lower, five aces being highest of all. Sleepers ncaa tournament.
The Bug
Some games, especially five card draw, are often played with a bug. This is a joker added to the pack which acts as a limited wild card. It can either be used as an ace, or to complete a straight or a flush. Thus the highest hand is five aces (A-A-A-A-joker), but other fives of a kind are impossible - for example 6-6-6-6-joker would count as four sixes with an ace kicker and a straight flush would beat this hand. Also a hand like 8-8-5-5-joker counts as two pairs with the joker representing an ace, not as a full house.
Wild Cards in Low Poker
In Low Poker, a wild card can be used to represent a card of a rank not already present in the player's hand. It is then sometimes known as a 'fitter'. For example 6-5-4-2-joker would count as a pair of sixes in normal poker with the joker wild, but in ace-to-five low poker the joker could be used as an ace, and in deuce-to-seven low poker it could be used as a seven to complete a low hand.
Lowest Card Wild
Some home poker variants are played with the player's lowest card (or lowest concealed card) wild. In this case the rule applies to the lowest ranked card held at the time of the showdown, using the normal order ace (high) to two (low). Aces cannot be counted as low to make them wild.
Double Ace Flush
Some people play with the house rule that a wild card can represent any card, including a duplicate of a card already held. It then becomes possible to have a flush containing two or more aces. Flushes with more than one ace are not allowed unless specifically agreed as a house rule.
Natural versus Wild
Some play with the house rule that a natural hand beats an equal hand in which one or more of the cards are represented by wild cards. This can be extended to specify that a hand with more wild cards beats an otherwise equal hand with fewer wild cards. This must be agreed in advance: in the absence of any agreement, wild cards are as good as the natural cards they represent.
Incomplete Hands
In some poker variants, such as No Peek, it is necessary to compare hands that have fewer than five cards. With fewer than five cards, you cannot have a straight, flush or full house. You can make a four of a kind or two pairs with only four cards, triplets with three cards, a pair with two cards and a 'high card' hand with just one card.
The process of comparing first the combination and then the kickers in descending order is the same as when comparing five-card hands. In hands with unequal numbers of cards any kicker that is present in the hand beats a missing kicker. So for example 8-8-K beats 8-8-6-2 because the king beats the 6, but 8-8-6-2 beats 8-8-6 because a 2 is better than a missing fourth card. Similarly a 10 by itself beats 9-5, which beats 9-3-2, which beats 9-3, which beats a 9 by itself.
Ranking of suits
In standard poker there is no ranking of suits What is the best hand in 3 card poker. for the purpose of comparing hands. If two hands are identical apart from the suits of the cards then they count as equal. In standard poker, if there are two highest equal hands in a showdown, the pot is split between them. Standard poker rules do, however, specify a hierarchy of suits: spades (highest), hearts, diamonds, clubs (lowest) (as in Contract Bridge), which is used to break ties for special purposes such as:
- drawing cards to allocate players to seats or tables;
- deciding who bets first in stud poker according to the highest or lowest upcard;
- allocating a chip that is left over when a pot cannot be shared exactly between two or more players.
I have, however, heard from several home poker players who play by house rules that use this same ranking of suits to break ties between otherwise equal hands. For some reason, players most often think of this as a way to break ties between royal flushes, which would be most relevant in a game with many wild cards, where such hands might become commonplace. However, if you want to introduce a suit ranking it is important also to agree how it will apply to other, lower types of hand. If one player A has 8-8-J-9-3 and player B has 8-8-J-9-3, who will win? Does player A win by having the highest card within the pair of eights, or does player B win because her highest single card, the jack, is in a higher suit? What about K-Q-7-6-2 against K-Q-7-6-2 ? So far as I know there is no universally accepted answer to these questions: this is non-standard poker, and your house rules are whatever you agree that they are. Three different rules that I have come across, when hands are equal apart from suit are:
- Compare the suit of the highest card in the hand.
- Compare the suit of the highest paired card - for example if two people have J-J-7-7-K the highest jack wins.
- Compare the suit of the highest unpaired card - for example if two people have K-K-7-5-4 compare the 7's.
Although the order spades, hearts, diamonds, clubs may seem natural to Bridge players and English speakers, other suit orders are common, especially in some European countries. Up to now, I have come across:
How Is 3 Card Poker Played
- spades (high), hearts, clubs, diamonds (low)
- spades (high), diamonds, clubs, hearts (low)
- hearts (high), spades, diamonds, clubs (low) (in Greece and in Turkey)
- hearts (high), diamonds, spades, clubs (low) (in Austria and in Sweden)
- hearts (high), diamonds, clubs, spades (low) (in Italy)
- diamonds (high), spades, hearts, clubs (low) (in Brazil)
- diamonds (high), hearts, spades, clubs (low) (in Brazil)
- clubs (high), spades, hearts, diamonds (low) (in Germany)
As with all house rules, it would be wise to make sure you have a common understanding before starting to play, especially when the group contains people with whom you have not played before.
Stripped Decks
In some places, especially in continental Europe, poker is sometimes played with a deck of less than 52 cards, the low cards being omitted. Italian Poker is an example. As the pack is reduced, a Flush becomes more difficult to make, and for this reason a Flush is sometimes ranked above a Full House in such games. In a stripped deck game, the ace is considered to be adjacent to the lowest card present in the deck, so for example when using a 36-card deck with 6's low, A-6-7-8-9 is a low straight.
Playing poker with fewer than 52 cards is not a new idea. In the first half of the 19th century, the earliest form of poker was played with just 20 cards - the ace, king, queen, jack and ten of each suit - with five cards dealt to each of four players. The only hand types recognised were, in descending order, four of a kind, full house, three of a kind, two pairs, one pair, no pair.
No Unbeatable Hand
In standard poker a Royal Flush (A-K-Q-J-10 of one suit) cannot be beaten. Even if you introduce suit ranking, the Royal Flush in the highest suit is unbeatable. In some regions, it is considered unsatisfactory to have any hand that is guaranteed to be unbeaten - there should always be a risk. There are several solutions to this.
In Italy this is achieved by the rule 'La minima batte la massima, la massima batte la media e la media batte la minima' ('the minimum beats the maximum, the maximum beats the medium and the medium beats the minimum'). A minimum straight flush is the lowest that can be made with the deck in use. Normally they play with a stripped deck so for example with 40 cards the minimum straight flush would be A-5-6-7-8 of a suit. A maximum straight flush is 10-J-Q-K-A of a suit. All other straight flushes are medium. If two players have medium straight flushes then the one with higher ranked cards wins as usual. Also as usual a maximum straight flush beats a medium one, and a medium straight flush beats a minimum one. But if a minimum straight flush comes up against a maximum straight flush, the minimum beats the maximum. In the very rare case where three players hold a straight flush, one minimum, one medium and one maximum, the pot is split between them. See for example Italian Poker.
In Greece, where hearts is the highest suit, A-K-Q-J-10 is called an Imperial Flush, and it is beaten only by four of a kind of the lowest rank in the deck - for example 6-6-6-6 if playing with 36 cards. Again, in very rare cases there could also be a hand in the showdown that beats the four of a kind but is lower than the Imperial Flush, in which case the pot would be split.
Hand probabilities and multiple decks
The ranking order of poker hands corresponds to their probability of occurring in straight poker, where five cards are dealt from a 52-card deck, with no wild cards and no opportunity to use extra cards to improve a hand. The rarer a hand the higher it ranks.
This is neither an essential nor an original feature of poker, and it ceases to be true when wild cards are introduced. In fact, with a large number of wild cards, it is almost inevitable that the higher hand types will be the commoner, not rarer, since wild cards will be used to help make the most valuable type of hand from the available cards.
Mark Brader has provided probability tables showing the frequency of each poker hand type when five cards are dealt from a 52-card deck, and also showing how these probabilities would change if multiple decks were used.
