The rarest tier
One in a Krillion: the answer almost nobody finds
“One in a krillion” started as a joke about impossible odds — an answer so rare it might as well be one in a krillion. In Krillion Infinite it is a real, specific thing: the single rarest accepted answer on a prompt, worth 100 points and a full 1,000 metres of depth.
What the tier means in the game
Every prompt in the bank has exactly one or two answers at this tier. They are real, valid answers — they obey the prompt — but they sit so far outside the crowd's habits that almost no player produces them under a 25-second clock. Land one and three things happen: 100 points, a kilometre of depth in a single move, and the golden tier card that tells you, correctly, that you have done something absurd.
Seven of them in one dive is the perfect 700 — the trench floor. It has the same relationship to normal play as a hole-in-one has to a round of golf: it is the story you tell, not the score you plan around. Planning happens at the Rare and Deep Cut tiers; One in a Krillion is what happens when preparation meets a prompt it happens to own.
Real examples from the bank
From the hand-curated shelf of the prompt bank:
- Name something sold in stick form (like deodorant; things on a stick don’t count). — rarest answer: Kolrosing stick
- Name a food made by mashing or puréeing (like guacamole) — rarest answer: Hasselback?
- Name a country with the letter D in its name — rarest answer: São Tomé and Príncipe
- Name a device made to blow air — rarest answer: Aeolian pilcrow
- Name a mammal smaller than a house cat — rarest answer: Etruscan shrew
- Name an internet service provider — rarest answer: Minitel
Notice the pattern: each one is correct, specific, and a little bit lateral — a thing you know, but not a thing you reach for. That gap between knowing and reaching is the entire game.
How rarity is decided (and why it is fair)
Rarity is fixed when a prompt is written, not calculated live. The bank ranks answers by how a crowd actually responds: the answer everyone blurts becomes Plankton, the fashionable “obscure” pick becomes Too Clever, and the tail of the ranking — answers that are valid but almost never volunteered — becomes Deep Cut and One in a Krillion. Because the ranking never moves, the same answer always scores the same, for every player, in every mode. Studying yesterday's answers is therefore real training: you are learning where the tail of the crowd's thinking actually lies.
