Games Like Krillion: Daily Trivia With a Rarity Twist
What is the opposite of Krillion?
If you want a game where the most common answer wins instead of the rarest, the closest opposite on this list is Noillirk: it rewards crowd answers, while Krillion rewards rare ones. If you want to keep the rare-answer idea but use a scoring source you can check, Uncommon Trivia ranks every correct answer by English Wikipedia pageviews and shows the number behind each score.
Neither game is an official Krillion mode; these are independent alternatives. Choose Noillirk for the inverted crowd-answer game, or Uncommon Trivia for a rare-answer daily trivia game with a transparent scoring measure.
Krillion hands out seven open-ended prompts a day, the same for every player, and instead of rewarding speed it rewards obscurity: an obvious correct answer barely moves your score, while a rare, correct one sends you deeper. That rarity-first scoring is unusual. Seldom is the closest match: one question a day, five guesses, and each answer scores from 0 to 100 by how obvious it is, which Seldom pictures as how many of 100 people would call it obvious, so the lowest total wins. Undersung applies the same instinct to music: name any song whose lyrics contain the word of the day, and the less that song has been streamed, the more points it earns; it can be played in English, French or Spanish. Top Answer Club runs the opposite incentive on purpose: a daily survey-answer game where you think like the crowd, with three lives to find the crowd's answers on the board. Fermi, linqed, and illivia stay in the open-trivia family without the rarity hook: Fermi scores three estimation questions by how close your guess lands, linqed asks four trivia questions that share one hidden linking word, and illivia gives hot-and-cold color feedback toward a single numeric answer. Uncommon Trivia also rewards rare correct answers, but it measures rarity its own way: every answer to its seven daily category questions is ranked by public Wikipedia pageviews, so any score can be checked. Try a few to see which twist on testing what you really know fits you.

Krillion alternatives: which one suits you?
Every game on this list is free to play in the browser and puts out a new puzzle each day, and each one scratches a different itch that Krillion players tend to enjoy: the hunt for a rare answer, reading the crowd, or working with numbers.

If you like the social side of daily trivia, Top Answer Club turns the idea around and rewards thinking like everyone else. Fermi and illivia suit players who prefer numbers to names, and linqed suits anyone who enjoys a puzzle with a final twist.
How Krillion-style games work
Krillion sums itself up as seven prompts a day, the same for everyone, where rare answers sink you deeper and obvious ones barely count. Games in this style share three parts: a fixed daily set of open-ended prompts that each have many correct answers, an answer list that decides what counts as correct, and a rarity value for every answer on that list. Any answer on the list is accepted, but the score depends on how unusual it is, so the challenge is less about knowing an answer than about knowing one that few other people would reach for.
The hard part for any game like this is deciding what counts as rare. Krillion's FAQ says its answer sets are merged from sources such as dictionaries, wiki pages, and encyclopedias, and that the way rarity is measured depends on the prompt, as the next section explains. Its featured answer, called the Krillion, is also picked partly for how satisfying it is to land on, not on rarity alone. Other rarity-scored games measure it differently: Undersung, for example, counts song streams.
The same habits help in every game of this kind. The first answer that comes to mind is usually the one everyone else gives, so it pays to spend a few seconds on a second or third idea. Krillion even has a label, too clever, for the go-to obscure pick that isn't really that obscure. An obscure guess only helps if it is really on the answer list, so the best pick is the rarest answer you are sure of, not a wild stab.
Krillion and Uncommon Trivia: how they differ
Both games give everyone the same seven prompts each day and reward a correct answer more when fewer people would think of it. The difference is in how rarity is decided and in what you see afterwards. Krillion's FAQ explains that rarity depends on the question: some prompts are scored against a familiarity database of how often a word or name turns up in what people read and write, while others get LLM assistance and a manual pass.
Uncommon Trivia uses one public measure for every answer: the median of its monthly English Wikipedia page views over the last six full months. Each question is a clearly defined set, such as the chemical elements or the US state capitals, built from Wikidata and Wikipedia lists. After every answer you see its monthly views, how many of the other answers it beats, and the three rarest answers you could have given, so every score can be explained and checked.
Krillion also offers themed packs, friends, and merch. Uncommon Trivia keeps to three free ways to play: the daily puzzle at 00:00 UTC, an archive of every past puzzle, and an unlimited mode with random categories, all without an account.
