Krillion | How to Play the Daily Dive Game
I've been messing around with Krillion for a few weeks now and honestly the thing that finally made it click for me was realizing that trying to be clever is exactly the wrong move, because everyone else is trying to be clever too, and once I stopped reaching for the obvious deep cut answer and started thinking about what almost nobody else would actually type in, the whole game sort of snapped into focus in a way it never had before. Every day you and everyone else get the same seven open ended prompts, 25 seconds each, one answer each, and the goal is to land on the rarest correct answer you can dig up before the timer runs out. Rare answers sink you deeper. Obvious ones barely count. You get the idea.
How a round actually works
Seven prompts a day, the exact same seven for every single player in the world, no luck of the draw at all, which changes how you approach every answer you type in, because you're not just being scored against yourself, you're being scored against the entire field on identical questions. So you get 25 seconds per prompt to type one answer and lock it in, and once the timer runs out you can't go back and edit anything. But here's the part that trips people up, you only get one answer per prompt, no multiple guesses, so you have to pick the one you think the fewest other people will type. And the rarer your correct answer is, the further down the dive you sink, while a common answer barely moves you at all.
What makes an answer rare
Krillion scores some prompts mechanically against a familiarity database, which is just a fancy way of saying how often a word or name shows up in the stuff people read and write, and if your answer barely appears anywhere it counts as rare. So other prompts get scored by an LLM with a manual pass from the developer instead, because there's no number to measure them against. Sort of a judgment call, if that makes sense.
There's also a daily gem answer called the Krillion, and a lot of players assume it's just the rarest answer of the day, but that's not quite right. Because past a certain depth rarity gets basically impossible to tell apart, so the gem is also picked for fun factor, the answer that feels most satisfying to land on, one that at least a few people get. There's a whole page on this in the rules guide if you want the details.

Frequently asked questions
Is Krillion free?
It's totally free. You play the daily dive in your browser at krillion.io and you don't even need an account. And if you feel like it you can buy themed packs, and any purchase turns off the ads across the whole site, which is nice.
Who makes Krillion?
One person. A developer named kp, who's a 22 year old American CS grad, built the whole thing solo. It's not a team, and they've also said a party game based on Krillion is in the works, and stuff like that.
Why is autocorrect so generous in Krillion?
Because some prompts have thousands of accepted answers, and a lot of those answers have aliases since people call the same thing different names. So autocorrect checks the aliases too, and being a letter or two off can still register. The developer's example is Threebanded Sheephead, which has sea donkey as an alias, and that's one letter off sea monkey.
Is there an app?
Not yet, but the developer has said one is planned eventually. For now it's just a browser game at krillion.io.
