Hey there,

The United States has Poker Three Of A Kind Probabilitybeen the most volatile of all the countries in the world when it comes to real money online gambling regulations. In the early days of the industry, you could find online sportsbooks bringing buses outfitted. Three of a Kind. Three cards of the same number or face value ('trips'). A B C D E F G H I J K L M N O P Q R S T U V W X Y Z. Three-of-a-Kind is the 6th best possible hand in the poker hand ranking system. The Straight ranks directly above it, with the best Straight being ace-high, also known as “Broadway”. There are only 3 hands that rank beneath 3-of-a-Kind. The hand that ranks directly under a 3-of-a-Kind is Two Pair.

The mini-series about writing code to match poker hands continues on! This article covers how to match a three of a kind.

You can also find links to the previously covered poker hands in the list below. The list also includes the ones we’ve yet to cover.

• Three of a kind
• Straight
• Flush
• Full house
• Four of a kind
• Straight flush (a non-ace-high straight flush)
• Royal flush (an ace-high straight flush)

Setup

The setup was also explained in the first article of the mini-series, you can check that out here. There, you’ll also a detailed description of the data structures used. But here is a quick rundown of the data structures used in the code:

Card values

Card suits

Card

Hand

And a hand is an array of Card objects:

Writing The Code To Identify A Three of a Kind

A three pair is similar to a pair, except you’re looking for three cards of the same value (rank) instead of two.

Poker Three Of A Kind

As you’ve done before, first you sort the cards by their rank, in descending order. We previously defined a “utilities” file, named CardMatchUtils.js, and added a function to it called, CardMatchUtils.SortCardsByDescendingValue, to help with that. You’ll be sorting the cards by descending value for all of the poker hands, so it’s very handy to have this reusable function.

You’ll also be using the “wild card”, which is a card that can assume the rank of any card. The image of the following hand would also qualify as a three of a kind:

The main function for the pseudocode for matching a three of a kind looks like:

As you can see, this function is very short and sweet, because of the CardsHaveSameValue function, which we previously wrote as the CardMatchUtils.DoCardsHaveSameValue function. If you haven’t seen CardMatchUtils.DoCardsHaveSameValue yet, that’s where the brunt of the work is done. This function determines if any cards in the hand have the same rank, specifying the number of cards we want to match, in this case, three.

Now time for a little fun 🙂

Below you’ll find a “hand” of five cards. You can set the suit and value of each card. It will then tell you if the cards you selected match any of the poker hands you’ve looked at so far:

• Pair (Jacks or higher)
• Two pair
• Three of a kind
