Is krillion a real number?
No, a krillion is not a real number. It is in the same family as zillion and gazillion: a playful -illion that means “a lot,” with extra krill.
The game leans into that joke. The rarest accepted answer on a prompt is labeled One in a Krillion and is worth 100 points. The ocean framing — Plankton at the surface, a trench at 7,000 m — is flavor on top of a popularity contest.
If you came here from a search for the word itself, the playable thing is still the daily dive at krillion.io. This site only logs the public answer sheets after reset.
