ELI5: Explain Like I'm 5

Edge-matching puzzle

Imagine you have a really cool puzzle with a bunch of different shapes and colors on it. But, you notice that some of the edges have weird, jigsaw-like shapes on them that don't fit with the other pieces. That's where edge-matching comes in!

Edge-matching puzzles have pieces with these weird edges that can only fit with certain other pieces. For example, if one piece has a zigzag edge on the left side, then you know the piece that goes next to it on the right side must have a matching zagging edge. It's like a giant game of putting together a puzzle within a puzzle.

The goal is to fit all the pieces together perfectly so that the edges match up and create a complete picture without any gaps. It can be a bit tricky at first, but once you get the hang of it, it's a ton of fun!
