Short answer: no — krillion has no defined numerical value in the standard sequence that runs million, billion, trillion. It is an informal -illion word, a comic way of saying "an extremely large, deliberately vague amount" — in the same family as zillion, jillion and bajillion. Here is how the word is used, why the internet keeps assigning it values anyway, and what it means inside the game that uses it.
What krillion actually means
Krillion resembles English's family of indefinite hyperbolic numbers: zillion, jillion, bajillion, gazillion. These are real words with real jobs — Merriam-Webster defines zillion as "an indeterminately large number" — but their job is vagueness, not quantity. Nobody who says "there were a zillion people at the concert" means a specific count; they mean "more than I could possibly tally." Krillion works as similarly informal wordplay, rather than a defined numerical value.
What the wordplay suggests
Krillion suggests a blend of krill and million. That reading explains the joke, but not who coined it or why the game chose the name. The game's public FAQ does not document its naming inspiration. Our article on One in a Krillion, the game's top rarity tier, focuses on the scoring tier rather than tracing the phrase's origin.
The real number sequence — and where krillion isn't
In the short-scale English sequence, each step below adds three more zeros.
- million — 10^6 (a 1 with 6 zeros)
- billion — 10^9
- trillion — 10^12
- quadrillion — 10^15
- quintillion — 10^18
- sextillion — 10^21
- septillion — 10^24
- octillion — 10^27
- nonillion — 10^30
- decillion — 10^33
The ladder keeps climbing by Latin prefix — vigintillion is 10^63 — and beyond the named rungs sits the famous outlier: a googol, 10^100, a 1 followed by 100 zeros. Krillion appears nowhere in this system. The test is simple: real -illion numbers derive from Latin number prefixes, and "krill" is a crustacean, not a prefix.
Why the internet gives krillion a value anyway
Search "krillion number" and you will find pages confidently stating a specific value for it — fictional googology wikis, Urban Dictionary entries, Reddit joke threads. Googology, the hobby of inventing and naming ever-larger numbers, is a real community with genuine creativity, and its members have proposed values for krillion more than once. But those values are fan fiction for numbers: playful, sometimes internally consistent, and recognized by no mathematician, standard or dictionary. Two different fan wikis don't even agree with each other. Enjoy them as creative writing about numbers — just don't cite them as fact.
What krillion means in the Krillion game
In the daily word game Krillion, the word does double duty, and the name is the pun. You answer seven prompts a day at krillion.io, and every valid answer is assigned one of six curated tiers. The public FAQ describes different rarity methods by question, not a live count of players. The 100-point top tier is called One in a Krillion. The arithmetic of that scoring is in our scoring math breakdown, and the full six-tier ladder lives on the rarity tiers reference.
An honest limitation
This page uses "real number" to mean a defined numerical value in the standard large-number sequence, not whether someone can use the word creatively. The origin of the game's name is not established by the scoring rules or by this site's saved answer data.
Frequently asked questions
Is krillion a real number?
No. Krillion is a made-up -illion word — the same family as zillion, jillion and bajillion — used to mean an extremely large but deliberately vague amount. It appears in no official number naming system: the real sequence runs million, billion, trillion, quadrillion and so on, with no krillion anywhere in it.
What does krillion mean?
Krillion is an informal, comic way to suggest an extremely large amount without specifying a value. It plays on krill and million. The game's public FAQ does not explain the inspiration for its name.
Is krillion bigger than a trillion?
There is no official answer, because krillion has no defined value. But as a made-up word it is meant to feel bigger: a trillion is a real, countable number (1,000,000,000,000), while krillion signals “so many I’m not even counting.” Fan wikis assign it specific huge values, but none of those are recognized.
