A royal flush is a specialized version of the straight flush, so let’s quickly go over the straight flush first.
Royal Flush, or How to Play the VPN-Nuts while Gambling Online 3 min read. Casino, poker, sports betting – which associations do these words trigger within you head? Las Vegas is probably one of them. However, nowadays you don’t have to go to Vegas in order to gamble, you only need an access to a computer and the internet.
A straight flush is a combination of a straight and a flush. A straight is where the cards are in sequential order by value, and there are least two different suits among the cards. And a flush is where all cards in the hand have the same suit, and are not in sequential order by value.
So then, a straight flush is a hand where the cards are in order by rank, and they all have the same suit.
Now, back to the royal flush. It’s a special type of straight flush where the highest card is an ace. The image featured at the top of this article is a royal flush.

Writing The Code To Identify A Straight Flush
We’ll start with writing code for a straight flush, because it’s a easier than the royal flush. The pseudocode for matching a straight flush looks like:
Straight Flush
Most of the code has already been written, thanks to the
CardMatchUtils file that contains three functions:
If you’re new to the series, we previously defined a “utilities” file, named
CardMatchUtils.js . This file is shared by all the poker hand matching functions, because it contains a several functions that they all use, and sorting the cards by their descending value makes performing the card-matching functions much easier.
How To Play Royal Flush Poker
So after sorting the cards in the hand, you want to check if the cards are both a straight and a flush. If so, the hand is a certifiable straight flush. Super easy ?
Royal Flush
As I mentioned before, a royal flush is a special version of the straight flush, where the ace is the high card.
The royal flush would New casino site. be a simple modification of adding a check to see if the first card of the sorted hand is an ace, and if so, you’d have a royal flush. However, we’re using wild cards, and they will throw a ? ? into that plan.
First, let’s consider this hand:
Once you’ve successfully determined that the hand is a straight flush, check the first card. As long as it’s an Ace, you’re good to go.
Because wild cards are already handled in both
CardMatchUtils.AreCardsStraight AND CardMatchUtils.AreCardsFlush , you don’t need to do anything specific for wild cards here.
However, what if you had a straight flush where the high card is not an ace, and wilds are present instead? Consider these hands:
All of these hands are royal flushes because of the wild cards!
If you look at what’s going on, for each wild card in the hand, the high card is the value of the ace, minus the number of wild cards in the hand. For example, if there is one wild, the high card (the first card in the hand) must be ace – 1 = king. You can use the numeric values defined in
CardValues to do the math. If there are, say three wilds, the high card must be ace – 3 = jack.
However, for the last hand with five wilds, this won’t work. If you took ace – 5, we’d have 9. And the high card is a wild, and
CardValues.nine != CardValues.wild .
Back when you setup
CardValues , you gave CardValues.wild an arbitrary, super-high numeric value (in this case, 100 ). So when checking that high card, you’ll want to use a greater-than-or-equal-to comparison, instead of equal-to.
So, the royal flush pseudocode looks like this:
