A Royal Flush is a poker hand made up of 10, Jack, Queen, King, and Ace, all of the same suit. It is the strongest possible hand in poker and cannot be beaten. A Royal Flush is actually a type of straight flush, but it beats all other straight flushes. In a 52-card deck, there are only four possible Royal Flush combinations, and they are all ranked equally. The odds of being dealt a Royal Flush are very low, and some players go their entire lives without making one. If you are lucky enough to have a Royal Flush, you should bet everything you have because it is unbeatable.
