Ok kiddo, so the National Puzzlers' League is a big group of people who really love puzzles! They get together and do all kinds of puzzles, like word games, crosswords, and brain teasers. They even create their own puzzles to share with each other!
It's like a big club where everyone is really good at solving puzzles and they help each other get better at it. They also have fun with it and make lots of friends who share their love of puzzles.
Sometimes they even have big competitions where they try to solve puzzles faster than each other. It's all about having fun with puzzles and getting better at them.
