About Krillionio
krillionio.com brings together daily trivia, unlimited dives, multiplayer battles and tools for exploring the answers.
An independent practice companion
krillionio.com is not affiliated with or endorsed by the original Krillion publisher. Our six-question games use our own question sets and fixed knowledge ratings. The archive contains our daily editions, and our answer tools validate only our published library.
Looking for the original daily dive or its themed packs? Play the original Krillion at krillion.io. Check its current rules and access options there; this site’s free practice does not unlock content on another site.
Game modes and answer tools
Start with six daily questions, continue with unlimited practice, or create a private battle for 2–8 players. Use prompt search and the answer checker to explore a tricky question between dives. Your profile keeps track of completed games and your strongest subjects.
Our answer policy
We start with bounded questions: a named list, an explicit date range or a rule that can be checked. Every prompt carries a source and every accepted answer has an explanation. The mixed practice set has 215 prompts across six subjects, plus a six additional Pixar questions in the movie collection. Movies also draws on film questions in the mixed set. The searchable reference library has 221 questions, including released daily additions. Unlimited means repeated play, not an infinite supply of distinct questions.
Canonical names and explicit aliases are normalized for case, accents and punctuation. Our live validator checks the prepared list; it does not ask an AI model to make a new factual judgment during your round. An absent answer is reported as “not found,” with a route to report an omission.
Where the facts come from
Practice sources include the European Union, NASA, IUPAC, NATO, FIFA, NBA, ITF, UEFA, the International Olympic Committee, United Nations, NOAA, EPA, ICPDR, New7Wonders and Pixar. The source for a particular rule appears on its prompt page. A reference-version date records the dataset edition; it is not a claim that every reference source is continuously monitored.
Publication and spoilers
New daily questions are released on an editorial schedule at 00:00 UTC. Today's questions and rules are public, with hints and answers available through optional reveals. Future editions remain unavailable. On dates without a scheduled addition, the game uses its stable rotating collection. Past editions keep their original questions and scores.
After a daily edition ends, its new questions can join the searchable library and unlimited practice in the next library update. Today’s and future additions are excluded from that practice pool. Shared practice links keep the same six questions when the library grows. Prompts may recur in future practice dives, so studying the library can help you recognize a later question. Answers stay collapsed until you choose to reveal them.
Report a missing answer
If a valid answer is missing, use the report button in the checker or during a round. Reports include the question and submitted spelling so the answer list can be reviewed.
