Before you play

  1. Rarer answers score more, from 5 to 100.
  2. 25 seconds on the clock. A miss costs 1 second.
  3. Spotlight doubles one prompt, and only when you score.

How to play

  1. Press Play. A daily round deals 7 prompts when the list is full, fewer when a category is still empty, and the same prompts for everyone on your local date.
  2. Type any real answer and press Enter. Capital letters, accents, punctuation, and a leading "the" do not matter. On a name of six letters or more, one wrong character still counts.
  3. You have 25 seconds. A wrong guess takes 1 second off the clock and you can try again. Turn the timer off before the round if you want to think, then use Pass when you are done.
  4. Arm Spotlight once per round to double that prompt. It is spent only when you score, and you can turn it off again before you submit.
  5. After each prompt you see your tier. A list of ten or fewer answers is shown in full, rarest first. A longer list shows the ten rarest and the ten most common. The share grid is colored squares. It does not include what you typed.
  6. From the answer box, Enter submits. Tab moves to Guess and Pass. Escape closes a dialog.

What science trivia is here

Science trivia asks you to name a thing in the field: an element, a body in the sky, a unit, a scientist, a species of particle. The textbook example is the one the clock will tempt you to type. The name from a footnote is the one that scores. Rounds on this page use science prompts only, under the same 25-second clock you can switch off before you start.

Science trivia prompts

32 science trivia prompts are in the catalog.

A science prompt ranks accepted names. It does not decide which fact is more true.

Each link opens that prompt's ranked answers, rarest first. The full index is on rarest answers .

How rarity is measured

Rarity is a rank inside one prompt. A name is common or legendary only beside the other accepted answers on that prompt. When the source names Wikipedia, the answer list is compiled from Wikidata (CC0) and monthly English Wikipedia pageviews set the rank. More views means a lower tier. When the source names Wiktionary, the rank uses monthly English Wiktionary pageviews. Any other source is placeholder popularity, not a live pageview count. Every prompt in this list records a pageview source: "Wikidata + Wikipedia pageviews (2026-10)".

Scoring tiers

Points for one prompt. Spotlight doubles those points once per round.
Tier What it means Points
Common Most players will say it 5
Familiar Widely known 10
Uncommon A solid, less obvious pick 20
Rare Specialist knowledge 40
Epic Few people land here 70
Legendary Among the least known answers on this prompt 100

Tips for this round

Science Trivia uses the same six tiers and the same Spotlight as the daily Rarest Answer game. Skip the famous legal name when you have a more specific one, and do not leave the set. The finding guide and the strategy guide are the long version.

Not a Krillion mode

Science Trivia is a Rarest Answer category, not a Krillion mode. Krillion is a separate game. The Krillion page says what this site could verify, and the games-like-Krillion page sets it next to other daily games.

Other rounds

Science Trivia questions

You name something the prompt accepts, such as an element, a body, or a unit. The rarest correct answer scores the most. You can turn the 25-second timer off before the round. A science round does not move the daily streak.

No. Accepted answers are all treated as correct. The rank is which name is less familiar inside that list, not which statement is more scientific.
