Krillion's hook — open prompts where the rare correct answer wins — sits in a family tree of daily games. If you've finished today's dive and want something in the same spirit, these are worth a bookmark. All run free in the browser with no signup.
The closest relatives
- Pointless (BBC) — the direct ancestor. A hundred people are surveyed, and the fewer of them who gave your answer, the better; an answer none of them gave is the best there is. Krillion swaps the panel of a hundred for the internet at large.
- Scattergories — the party-game grandparent (1988): an answer another player also wrote down earns nothing. Originality as the scoring rule, around a table instead of a leaderboard.
- Anything Grid — fill each cell of a grid with an answer matching both its row and column, and the more obscure the answer, the better it scores. The closest browser-game cousin to Krillion's rarity scoring.
- Rarish — give two answers to one daily trivia question, then compare their rarity.
Daily trivia with a shared set
- Brainer — a quiz-show format with questions from several categories and a new set each day.
- Quizl — five multiple-choice trivia questions daily, with a streak for regulars.
- Daily Tens — ten items sit at the top of today's category; find them all.
- GuessTen — name the ten entries at the top of today's category; nothing outside them counts.
- Tightrope — daily trivia questions across a range of topics.
- Daily Fact or Fiction — one statement a day, two buttons.
- Real Bird Fake Bird — seven prompts a day; decide which birds are real and which were invented.
- 100 of Us — "of 100 people in the world, how many…?" — press and hold to guess, then see the real number with its source.
Daily puzzles with a twist
- Chrono — put six events in chronological order in three tries.
- Rankle — rank six things in four guesses; a different category every day.
- Sortem — drag countries, cities, foods and more into the correct order.
- Searchle — name the Google autocomplete suggestions that top a given query.
- Costcodle — guess the price of a Costco item in six tries, with higher/lower after each.
- Blinkle — an image flashes for five seconds; can you identify what you saw?
- Foodguessr — a dish in a photo, and the country or region it comes from to work out.
- riddl.ing — one handmade riddle a day with five clues.
- Anidoku — daily anime sudoku: fill a 3×3 grid with titles matching both the row and column clues.
Why the format works
Shared daily prompts turn trivia into a social comparison: everyone faces the same seven questions, so scores are comparable and the post-game "what did you say?" conversation writes itself. Krillion's twist is that knowledge alone doesn't win — you're also guessing what the crowd will say, which is why the rarest correct answer beats the most impressive wrong one.
