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.
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 has no assigned value in this sequence.
How to read an invented value
A fictional number system can define its own value for a word. Keep that definition with its source. For ordinary short-scale arithmetic, use a defined term such as trillion or write the power of ten explicitly.
What krillion means in the Krillion game
In the daily word game Krillion, the word names a score tier. You answer seven prompts a day at krillion.io, and every valid answer is assigned one of six curated tiers. 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.
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. In the game, One in a Krillion names the 100-point answer tier.
Is krillion bigger than a trillion?
There is no official answer, because krillion has no defined value. A trillion has a defined short-scale value of 1,000,000,000,000. Krillion expresses an indefinite large amount, so the two cannot be placed on a numerical scale together.
