Why is this the answer?

The answer is cards because this is a very clever riddle that plays a fun trick with words! When you first hear the question, "What has 13 hearts but none beat?", you might start thinking about real animals or people, since they are the ones who have hearts that beat. That is the tricky part of the riddle. It is trying to make you think about something alive, when the answer is actually an everyday object you can hold in your hands. The first clue is "13 hearts." To solve this, you need to think about a standard deck of playing cards. Maybe you have seen your family or friends play a game like Go Fish, Rummy, or Crazy Eights with them. A deck of cards is divided into four main groups, which are called suits. The four suits are Clubs, Diamonds, Spades, and, most importantly for this riddle, Hearts! Each of the four suits is represented by a special picture. The Heart suit has a small, red, heart-shaped symbol printed on its cards. In every full deck of cards, there are exactly 13 cards for each of those four suits. That means there are 13 Heart cards in the deck, starting from the Ace of Hearts all the way up through the numbers to the Jack, Queen, and finally the King of Hearts. So, the "13 hearts" are the 13 cards that all belong to the beautiful, red Heart suit. Now let us look at the second clue: "but none beat." This is where the riddle gets even more fun and a little sneaky! A heart that beats is a real, living organ inside a person or an animal that pumps blood to keep them alive. Your own heart beats many times every minute! But the hearts on playing cards are just pictures printed on a piece of paper or thin plastic. They are only symbols and do not have any blood or life inside them, so they certainly cannot beat or pump anything. They are completely still and flat on the card's surface. This riddle is a perfect example of how clever puzzles use words that have more than one meaning to make you think in a new way. It uses the word "hearts" to mean both the suit in a card deck and the actual organ in a body. Once you know about playing card suits, the answer suddenly becomes clear and the trick of the puzzle is solved!
