Royal flush beats a straight flush in poker. A straight flush is when you have five cards in a row of the same suit, with the royal flush being the highest-ranking series with the cards A, K, Q, J, and 10, all of the same suit. What can beat a straight flush, then? When people first start playing, it is common to ask, “What beats a straight flush?” However, the answer is simple: the royal flush. Not only does it serve as powerful and beautiful, but it is also a terrible sight to see in the game. Other than that, there is no hand combination in poker that outranks the straight flush. This makes the straight flush a hand that few will never get to, talking about its devastating strength. However, when you get it, keep in mind that you can still lose it if your opponent has a royal flush. Therefore, play only when you are confident. A straight flush-ridded game will likely be one you can never experience again.
