Frequently asked questions
The game, the scores, and what this site does.
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. Finish a dive and choose Dive Again to start a new session. The mixed library has 36 prompts across six categories; the movie pack adds six more. Questions can repeat.
What can I play in Deep Bench?
The sports practice dive has six questions about men’s FIFA World Cup champions from 1930 through 2022. Read the date range on each prompt, then choose a qualifying country that is less likely to be your first thought.
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?
Six questions cover Pixar feature films released from 1995 through 2009. Read each release-year or title rule. The movie question library includes accepted film titles, alternate spellings and explanations.
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 people 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.
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.
