ELI5: How do puzzles benefit our brains?

Like, yeah I can see how it helps keep your brain active by like ‘solving problems’, but how else does it benefit the brain? 

How does it improve the brain?  What specifically happens? Are there other types of ‘puzzles’ we could create to better help ourselves or even overcome certain problems?

Exercises memory too I guess?

Puzzles mostly help your brain get better at doing those specific kinds of puzzles. Most of the “train your brain using these puzzle games” style services or activities tend to greatly exaggerate the expected benefits. There might be some from just generally being active, and some skills that you practice or learn in the process of doing puzzles might help with working on more general problem-solving, logic or spatial reasoning, but for the most part, it’s not actually doing anything special to your brain to improve it in any particular way.
