About Krillion Free
Krillion Free is a small browser game for people who like thinking sideways. You get a prompt, 25 seconds and one box to type in, and the goal is not to be right but to be right in a way nobody else was. We built it to be quick to start, free to play and fair to everyone.
Krillion Free is an independent fan project. It is not made, endorsed or approved by krillion.io or the people behind it. The original game lives at krillion.io.
The prompts
All prompts come from our own library of more than 850. We draft them with AI tools and then keep only the ones that have a big pool of correct answers, a clear line between right and wrong, and no need for knowledge of one particular country. "Name a fruit" works because there are hundreds of fruits. A prompt with a single answer, or one that asks for an opinion, gets cut.
The answer sheets
Every prompt has a sheet: a long list of correct answers running from the obvious to the obscure, with the usual alternative spellings and names. We estimate which answers players type most often, which sets the Plankton and Schooler bands. Then we hand-pick the Too Clever trap and one or two One in a Million jackpots, and write a short fact for each jackpot. When players point out a mistake through the contact form, we fix the sheet.
Judging
Your answer is matched against the sheet with some slack: capital letters, accents, a leading article, a plural ending and small typos don't matter. If the answer is not on the sheet, an AI referee decides whether it is real and fits the prompt. Correct answers we missed score a Deep Cut, and the verdict is stored so everyone gets the same ruling. The full scoring rules with examples are in the strategy guide.
The daily set
Each day takes one prompt from each of seven categories: nature, geography, film and music, food, sport and games, science and technology, and everyday life. The set changes at 00:00 New York time and is the same for every player. Dive #1 went live on November 11, 2026. The themes draw on the same library, grouped by subject.
Your data
There are no accounts. Your streak and results live in your browser. Our server receives the prompt, your answer and the date so that it can score the answer and count how often each answer is given; to keep one person from skewing those counts it stores a one-way hash of your IP address, which cannot be turned back into the address. The site uses Google Analytics to count visits. Everything is spelled out in the privacy policy.
