Independent fan-made trivia game. Not affiliated with, endorsed by, or connected to krillion.io or its creator.
What we are making
We make an English-language trivia game about finding a valid answer beyond the first familiar example. Each session contains seven open-ended prompts, with 25 seconds per answer. You can finish, inspect your results, and start again without an account or a daily allowance. Geography, sports, and general knowledge currently share one mixed question pool. This is a small first edition with 30 original prompts, not an exhaustive encyclopedia. Repeated questions are possible, and the catalogue will need careful expansion rather than an endless stream of unchecked text.
Where the questions and scores come from
The prompts and answer examples were newly composed for this project with language-model assistance, using general knowledge. We do not import another game's daily questions, answer lists, screenshots, databases, or rarity data. Each prompt has three familiar examples and three less familiar examples. Those labels are editorial calibration choices, not survey results. The scoring system combines offline model-assigned rankings with local occurrence counts from a deliberately authored English practice corpus. The corpus is synthetic and reflects those design choices; it does not establish how frequently an answer appears across English writing in general.
No live AI service is used when you play. The server matches your answer to the saved catalogue, handles limited typo correction, and assigns a repeatable tier. This makes the experience fast and predictable, but a sensible answer can still be missing. Please report omissions with enough context to identify the exact prompt. A rarity score is game feedback, not a claim about your intelligence, a factual authority, or a comparison with every other player.
Open-source foundations
The game builds on the MIT-licensed openkrillion.com-service implementation by VulcanEon. Its server-side timing, ownership checks, matching logic, and seven-round structure provide the foundation. Our visual design, question bank, calibration corpus, and page content are maintained separately. The inherited LICENSE and THIRD_PARTY_NOTICES.md remain intact in the source repository. An accompanying provenance note explains which upstream features and assets this edition removed.
