Why Spot-the-Difference Puzzles Make Your Brain Work Hard
You’re not the only one who thought this puzzle was hard. These problems work by messing with the brain’s ability to find patterns.

They help you get better at focusing, being aware of what you see, and paying attention, which makes your observations sharper over time.
