Trivia where the obvious answer loses
Krillion Unlimited asks simple open questions, such as "Name a fruit" or "Name a bird that cannot fly", and rewards you for answers that are correct but uncommon. Banana is right, but nearly everyone says it. Jabuticaba is right too, and hardly anyone does.
Each correct answer is worth points, and each point takes your krill ten metres further down, from the warm surface water past coral, whales and shipwrecks into the trenches. Seven questions make a set. When a set ends you start another one straight away, because on this site the sets never run out.
How a set goes
- Press Start a set. You get seven random questions, one from each category: nature, geography, film and TV, food and drink, sport and hobbies, science, and everyday life.
- Answer within 25 seconds. Type one thing that fits the question. If it is not on our sheet you may try again, three attempts in total, while the ring still has time left.
- See how deep it took you. The result screen shows the tier of your answer, the points and, for the rare prize answers, a short fact.
- Read the answer sheets. After the seventh question, tap any question to see the full sheet: prize answers, examples for every tier and a box for testing other ideas.
Points and tiers
| Tier | Points | Depth | Typical answer |
|---|---|---|---|
| One in a Million | 100 | 1,000 m | One of the one or two hidden prizes we chose for the question. Each comes with a fact. |
| Deep Cut | 85 | 850 m | A correct answer that only a handful of players come up with, including correct answers our sheet does not list. |
| Rare | 60 | 600 m | Uncommon, but something many people would recognise once they hear it. |
| Schooler | 30 | 300 m | A sound, mainstream answer that a fair share of the swarm also gives. |
| Too Clever | 15 | 150 m | The answer people pick to look original, so many of them pick it. |
| Plankton | 10 | 100 m | The first five answers on almost everyone's mind. |
A wrong answer, or no answer before time runs out, earns nothing. The best possible set is seven prizes: 700 points and the hadal floor at 7,000 metres.
Four ways to play
Endless sets
The heart of the site. Random questions from a library of more than 850, as many sets as you want, with the timer pausing while a menu is open.
The daily set
One set that every player gets on the same day, with a streak and a comparison with the other players. Find it under Daily set.

Chapters on one topic: food and drink, animals, places, film and TV, sport and games, science. Open them from the menu or the Themes button.
Shared sets
Every endless set has a number. Share your result and the link opens the same seven questions for whoever taps it.
What you swim past
The depth scale follows the layers oceanographers use. The epipelagic layer near the surface gets enough light for plants and coral. The mesopelagic, or twilight layer, starts at 200 m. From 1,000 m the bathypelagic layer is completely dark, and from 4,000 m the abyssopelagic layer sits close to freezing. Below 6,000 m only the trenches remain: the hadopelagic layer. On the way down you pass the deepest freedive on record, the depth where vampire squid live, the 1934 bathysphere record, the wreck of the Titanic and the Bismarck.
Habits of deep swimmers
- Treat your first idea as a warning. If it came to you instantly, it probably came to everyone else too.
- Be wary of the famous oddity. The answer that feels quirky, like durian among fruits, is often Too Clever.
- Think in subtypes and regions. A named variety, a local dish or a species name usually beats the general term.
- Read the rule twice. Questions with a letter, length or word count rule reject anything that breaks it.
- Use the answer sheets. Two minutes with a sheet after a set will give you answers for the next time a similar question comes up.
Questions people ask
Is Krillion Unlimited really unlimited?
Yes. Every time you press Start a set you get seven new random questions, one from each category, and you can keep going for as long as you like. Only the daily set is limited to one a day.
Who runs Krillion Unlimited?
A small independent team of game makers. Krillion Unlimited is a fan-made game in the rare-answer style and is not affiliated with or endorsed by krillion.io. More on the about page.
Can I replay a set or send it to a friend?
Yes. Every set has a number, and the link in your share text opens exactly the same seven questions, so you and your friends can compare depths on equal terms. Past sets are also listed in My record.
Does it work on a phone or a Chromebook?
It runs in any current browser on phones, tablets, laptops and Chromebooks. There is nothing to install and no sign-up.
Why did a correct answer score so little?
Points depend on how common an answer is, not only on whether it is right. Answers almost everyone gives are Plankton and earn 10 points; uncommon correct answers earn up to 100. The guide walks through a full example.
