"King of the Hill" is a game where one person tries to stay on top of a hill while other people try to knock them off. Imagine you're playing on a big playground with a hill in the middle. The person on top of the hill is the king or queen, and everyone else wants to be the king or queen too.
To play, one person starts on top of the hill (the king or queen), and everyone else tries to push or tackle them off the hill. If the king or queen falls off the hill, the person that pushed them off becomes the new king or queen. The game goes on until everyone has had a turn as the king or queen or until the players get tired and want to stop playing.
People like playing "King of the Hill" because it's fun to try to be the best and stay on top. It's a simple game that doesn't require any special equipment or complicated rules. It's just about having fun and competing against your friends.
