What kind of game is Krillion, exactly?
It is a rare-answer trivia game: an open prompt, many valid answers, and a payout that rises with how few people would say yours. That puts it closer to Scattergories than to Wordle, with a scoring twist borrowed from pub-quiz “pointless” formats where the least-given correct answer wins. Anything on this list has at least one of those three parts: open prompts, a rarity payout, or a daily clock.
Games with a rarity payout
Wordillion
The closest relative here, and the one built for Krillion players who also play Wordle. Prompts are one or two criteria (“is a bird”, “is a verb and contains a K”), answers are capped at five letters, and every answer is scored twice: once for rarity across six tiers, once as Wordle tiles against a hidden five-letter word. Between rounds you pick a boon that changes the next round or the whole run, so it plays as a roguelike. Daily run, endless mode after you beat par, and a 60-second time trial. Free at Wordillion. The full comparison is on its own page.
Noillirk
Krillion spelled backwards and scored backwards: the most common answer pays the most. It is the Family Feud instinct instead of the pointless-quiz instinct, and it is surprisingly hard to switch between the two on the same day. Good for finding out whether you actually know what other people think.
Pointless-style quizzes
The UK game show that popularised “score low by being obscure” has spawned many unofficial browser versions. The survey mechanic is different from Krillion's curated rarity, but the skill transfers directly.
Games where distance is the score
Contexto
Guess the secret word; every guess is ranked by how close in meaning it is, using word embeddings. No prompt, so it is less trivia and more vocabulary cartography, but the feeling of “I know a word that's near this” is very Krillion.
Semantle
The original semantic-similarity guesser. Harder and slower than Contexto, with a cold/warm scale. If you like Krillion for the thinking rather than the clock, start here.
Category sprints
Sporcle
Thousands of timed “name all the X” quizzes. There is no rarity payout, but Sporcle is the best training ground for Krillion prompts there is, because it teaches you the full depth of a category rather than the first three things you'd say.
Scattergories (and its browser clones)
One letter, twelve categories, a timer, and points only for answers nobody else wrote. It is the board-game ancestor of the whole rare-answer genre and still the best party version.
Daily puzzles with the same rhythm
Wordle
Mentioned because Krillion players almost always play it too. It is the opposite design: one hidden target, no credit for creativity. See new types of Wordle for the variants that bend that.
Connections
Sixteen words, four hidden groups. Different mechanic, same daily social loop and the same pleasure in spotting the category other people miss.

Noillirk, which scores the most common answer highest instead of the rarest. Family Feud works on the same principle.
