Rarity game night: the party game where the rarest answer wins

A rarity game night is a party trivia night where the rarest correct answer wins. The host reads an open prompt — “Name a country with the letter Z in its name”, “Name a cheese from France” — every player writes one answer in secret, and answers are scored by how unusual they are: the answer everyone wrote scores least, the valid answer nobody else thought of scores most. It takes four or more players, about thirty minutes, and no equipment beyond paper and a timer.

Split the room into teams or play every player for themselves. The host reads a prompt and gives everyone 25 seconds — the same clock Krillion Infinite uses — to write one answer. Reveal answers one player at a time, lowest-scoring first, so the room feels the ladder climb. Play seven prompts for a full game, the same length as a Krillion dive, and total the scores at the end. The reveal is the entertainment: a player who wrote Zambia watches Bosnia and Herzegovina take the round, and the room learns something in the same breath.

Use prompts with many valid answers, not one-answer trivia. The best prompts start with “Name a...” and accept a whole shelf of answers: countries, cheeses, movies, animals, instruments. Avoid yes-or-no questions and single-answer facts — a rarity game needs a crowd of possible answers for rarity to mean anything.

You do not need a survey of a hundred people to score a rarity night — the room is the survey. Score each round by how many players gave the same answer: an answer everyone gave scores 10, an answer two or three players shared scores 30, an answer only one player gave scores 60, and a valid answer the host judges genuinely obscure scores 85 or 100. For a ready-made ladder, steal Krillion Infinite's tiers outright: Plankton 10, Too Clever 15, Schooler 30, Rare 60, Deep Cut 85, One in a Krillion 100 — and judge each answer against the ladder on the matching prompt page after the round, which is where the arguments — the good kind — start.

Two house rules keep it honest. First, an answer must be valid: it has to actually fit the prompt, or it scores zero no matter how obscure it is. Second, the “Too Clever” rule: if an answer feels like the clever pick everyone is proud of, it probably is — and the room will have several of them. Genuinely rare answers feel quieter and lonelier than the fashionable ones.

No screen at all: the host reads prompts from any list, players write on paper, and the host scores by counting duplicates in the room. It works at a table, on a trip, or anywhere a phone would be a distraction. With a screen, skip the scoring labour entirely: send the room a challenge link and everyone plays the same 7 prompts on their own device, with Krillion Infinite's full ranked ladders revealed after each answer. Warm up first in Unlimited mode so the night's first dive is not anyone's first dive, and study the strategy guide if the room wants to know why the quiet answers keep winning.
