A card game is like playing with special paper rectangles with pictures and numbers on them. There are many kinds of card games with different rules, but most card games involve players competing to get higher or lower numbers, or to match cards with the same pictures or suits.
In some card games, like Go Fish, players try to collect sets of matching cards by asking each other if they have certain cards. In other games, like Poker, players bet on who has the highest or best combination of cards in their hand.
Sometimes, certain cards have special powers or abilities that can change the game, like Wild Cards or Action Cards. Some card games have a certain order of suits, like Hearts or Spades, that need to be followed when playing cards.
It's important to know the rules of each card game in order to play and win. Card games can be played for fun with friends and family or for competition in tournaments.
