Knowtilus: Krillion Trivia

Most trivia games want the right answer. Knowtilus wants the rare one.

Every question in this trivia quiz is open-ended: "Name a moon in the solar system." "Name a type of spider." Any correct answer counts, but the fewer players who said it, the deeper your submarine sinks. Answer "Moon" and you'll stay in the shallows. Answer "Goliath birdeater", which only 0.21% of divers thought of, and you plunge toward the abyss.

A daily quiz with a twist

Every day brings a new dive: seven questions, one answer each, and a ticking clock. Everyone plays the same daily trivia, so you can compare your depth with friends and find out who has the most original general knowledge.
