Our word practice includes NATO codewords, Greek letters, English grammar, Japanese scripts and punctuation. The rule names the exact list: primary auxiliaries are be, have and do, while modal verbs form a different set. For NATO word-length questions, Alfa has four letters even though Alpha is an accepted input alias.
Read the question’s exact scope.
A clear category is the best starting point. Review the prompt library for the exact rule, use the checker for spellings, and read the answer explanations to understand why each entry qualifies.
Before your next dive.
How does rare-answer trivia work?
Read a question and type one answer that fits. Less obvious accepted answers earn more knowledge points, taking you deeper into the ocean. A dive has six questions with 20 seconds for each answer.
Can I play Krillion Unlimited for free here?
Yes. Unlimited practice is free and does not require an account. The mixed library has 215 questions; six additional Pixar questions are available in Movies. Other movie questions also belong to the mixed set. New dives prioritize questions you have not encountered on this device, then revisit older ones. Completed daily additions enter practice with library updates. Shared links keep the same questions. Focused topics contain six questions and can repeat.
What can I play in Deep Bench?
Deep Bench is our free Sports practice mode with 52 questions. Mix sports or choose a focused six-question topic. Each question states its reference season or year range.
What does the answer checker verify?
It matches your answer against the selected question’s answer list, including recognized alternate names and spellings. A match shows the canonical name, fixed score and a factual explanation. You can report an answer that is missing.
How does the Rare Answer Finder choose its picks?
It compares only listed answers for the chosen question. Highest score shows the most points; quickest to type uses the shortest accepted name or alias. Balanced pick chooses the shortest spelling among answers worth at least 65 points when available. These are fixed ratings, not predictions of other players.
What can I play in At the Movies?
Each dive selects six of 18 movie questions, covering Pixar, Oscar winners, film series, directors and Bond actors. New dives prioritize questions you have not seen in this browser. Check whether a question uses release years or ceremony years. Original Pixar links still select their original six questions.
How do scores and crowd counts work?
Knowledge points are fixed editorial ratings, with 10 metres per point and up to 6,000 metres per dive. Daily crowd counts come from actual answers submitted on this website. Those counts show how many recorded rounds chose your answer and do not change your knowledge score.
When does the daily dive reset?
A new daily dive opens at midnight UTC. Everyone receives the same six prompts for that UTC date. You can keep playing in Unlimited between resets, or replay a previous day from the archive.
Is this the original Krillion game?
No. krillionio.com is an independent practice companion. The original game is at krillion.io. Our six-question dives, fixed knowledge scores and archive belong to this site; our checker does not predict the original game’s validator.
Can I play with friends?
Create a Battle room and share the room link with 1–7 friends. Everyone answers the same question privately. Matching answers cancel each other out, including matching answers written with different recognized spellings.
Can I make the game bigger?
