About this game
The basics of how the world works — how many can you actually answer?
Why is the sky blue? Why do dogs bond with humans? Why are pyramids shaped like that?
The everyday "why?" trips you up the moment you're asked. There's general knowledge every adult should hold.
This game offers 80 picture-based 4-choice questions across 8 categories — animals, nature, world landmarks, food & living, science, space, the human body, and culture & history — studied alongside Professor Neumann.
"What is this?" "Why does it happen?"
Look at the image, pick your answer, and let the explanation make it click.
How to play is simple.
・Read the question and look at the image
・Choose from 4 answers
・After answering, deepen your knowledge with Professor Neumann's explanation
Get it right and feel sharper. Miss it and find a fresh "huh, really?"
By question 80, the world will look a little richer.
Squeeze in a relaxed knowledge boost on your commute, on a break, or before bed.
Perfect for sparking "Did you know?" chats with family and friends.
World-class general knowledge, at your fingertips.
So — can you earn the adult certification?
