Find a correct answer that goes beyond the obvious.
Krillion turns trivia into an ocean dive. Read an open question, type your answer and discover its rarity. Every recognised answer adds to your score, and rarer answers take your Krill further into the deep.
Seven questions, one dive
Each dive has seven rounds. In the Daily Dive and themed packs, you have 25 seconds per question to find a correct, uncommon answer. Watch the ocean change as you descend and aim for a personal best of up to 7,000 metres. If an answer is not recognised, you can try another while time remains.
A fresh Daily Dive
Return for a new daily quiz at midnight UTC. Follow your daily streak and discover the previous day's rare finds on the Daily Dive leaderboard.
Choose your world
Explore pop culture, movies and TV, sports and geography through the four free packs: Endless Pop, Movies & TV, Game On and Around the World. Premium adds Anime & Manga, Video Game Vault, Brand Empires and World Flavours.
