That's kind of the genius of puzzles like these (we can't take credit for inventing it - Spot the Ball has existed for a long time in the analog world) is that it's a mix of skill and luck, so you can fool yourself into thinking you're amazing at it, when in reality the next photo might trip you up completely.
