Score bands

Your final score places you in one of these bands.

Freshly LandedYou just got here, haven't you?

Don't worry — most people don't know that frogs can freeze solid and come back to life. You're not behind, you just haven't started paying attention to the weird stuff hiding in plain sight. Next time a random fact pops up on your feed, give it a second look. Your planet knowledge is about to level up.

Curious WandererYou've started noticing the strange details

Not bad at all. You probably watch the occasional science video and actually finish it. You're the kind of person who goes down a Wikipedia rabbit hole at midnight. A few more facts and you'll be the one dropping random knowledge bombs in group chats.

Trivia HoarderYour brain is full of things most people don't know

Your random knowledge stash is seriously impressive. You're the friend who randomly says 'did you know bamboo grows a meter a day?' during dinner and everyone just stares. People think you're a walking encyclopedia, but really you're just addicted to bizarre facts.

Planet DecoderYou understand this planet better than most

You don't just know random facts — you know exactly when to drop them for maximum effect. Your curiosity about this planet goes deeper than casual browsing. Honestly, did you binge an entire nature documentary series in one sitting? Because it shows.
