What is Krillion?
Krillion is a free daily trivia game you play in the browser. Instead of rewarding the “correct” answer, it rewards the rarest one: every prompt accepts many valid answers, and each is scored by how few players type it. Answering “scrambled” to an egg-prep prompt keeps you near the surface; typing “haminados” sends you plunging.
A fresh set of seven prompts — identical for every player — goes live each day at midnight US Eastern time. You have about 20 seconds per prompt to commit to one answer, and every point you earn sinks your dive another 10 metres toward the trench floor. Answer nothing and you still descend a little; nail seven rare answers and you touch 7,000 metres.
The framing is all ocean: prompts are “the dive,” low-scoring answers are “Plankton,” the rarest answers are “One in a Krillion,” and your daily descent is logged like a dive computer. It was created by a solo developer, and the whole thing takes about three minutes a day — which is exactly why players keep streaks and compare depths with friends.
How a daily dive plays out
You open today’s dive and read the first prompt — say, “Name a country whose name starts with A.” The obvious answers surface instantly: Argentina, Australia, Austria. Those are Plankton, worth 10 points each. You have roughly twenty seconds to think past them: Andorra? Armenia? Those score better. Antigua and Barbuda? That’s a Deep cut. You type one answer, the timer judges nothing, and the next prompt arrives.
After seven prompts you get your score, your depth, and — later, once the official sheet is out — the full answer data showing exactly where your picks landed. That reveal is half the game: everyone swam in the same water, and the sheet proves who found the quiet corners.

The questions only — no spoilers here. Taps take you to the spoiler-safe answer sheet.

Scoring in one table
| Tier | Points | Depth | Example vibe |
|---|---|---|---|
| Plankton | 10 | +100 m | The answer everyone types first |
| Too Clever | 15 | +150 m | You thought it was obscure — it wasn’t |
| Schooler | 30 | +300 m | Familiar, but one step off the main path |
| Rare | 60 | +600 m | Uncommon but comfortably valid |
| Deep cut | 85 | +850 m | Only a small share of players land it |
| One in a Krillion | 100 | +1,000 m | The rarest confirmed answers on the sheet |
Answer validity is checked against the official accepted-answer list, and each day’s tiers here are confirmed against that sheet — so the numbers on our daily answers page match what the game actually scored.
Why the rarest answer wins
Most trivia games reward knowing more. Krillion rewards knowing differently: the winning move is guessing what everyone else won’t type — while staying valid and spellable before the timer. That single twist changes how you think. “Fannie Farmer” is a perfectly real celebrity chef with a famous cookbook, yet almost nobody reaches for her while Gordon Ramsay sits one reflex away. “Mycelium” is a building material only if you’ve read about mushroom bricks — and if you have, that’s 100 points.
It’s also why the game rewards broad, strange knowledge: regional phone carriers, historical search engines, hairstyles from the 1800s. You are not competing against a quiz master; you are competing against the crowd’s first thought. The crowd is predictable, and that’s the exploit.
How the answer sheets are made
Per the official FAQ, every prompt’s answer set is built by aggregating whatever datasets fit the question — dictionaries, wikis, encyclopedias — then merging and cleaning them into one list. Rarity is judged per question: sometimes mechanically, against a database of how often words and names appear in real text; sometimes with LLM assistance plus a manual pass. The 100-point gem isn’t always the statistically rarest answer — past a certain depth, rarity stops being distinguishable, so the final pick balances rarity with fun and stays reachable by at least a few players.
Practice between dives
One dive a day not enough? The official menu has an Unlimited (∞) mode — endless mixed-topic sets with a softer 25-second timer — plus themed packs, chaptered collections that drill single topics like language, movies and geography at your own pace. Your history lives in the Logbook, and past dives can be revisited there. We keep guides for all of it: Krillion Unlimited, themed packs, and the full answer archive when you want to study real sheets instead of guessing blind.

Krillion FAQ
What is Krillion?
Krillion is a free daily trivia game you play in the browser at krillion.io. Each day you get the same 7 open prompts as every other player and type one answer per prompt against the clock. Instead of rewarding the “correct” answer, Krillion rewards the rarest valid one: the fewer players who typed your answer, the more it scores. The name is a play on “one in a trillion” — the rarest answers on each sheet are called “One in a Krillion.”
How many prompts are in a Krillion game?
Seven. The prompts are identical for every player on a given day and always appear in the same order, each with its own countdown of roughly 20 seconds. One dive per day — when it’s done, the next one arrives at midnight US Eastern time.
How does Krillion scoring work?
Accepted answers are grouped into rarity tiers: Plankton (10 points), Too Clever (15), Schooler (30), Rare (60), Deep cut (85) and One in a Krillion (100). Every point sinks your dive 10 metres deeper, so a perfect 700-point run touches the trench floor at 7,000 metres. A run of nothing but “Rare” answers scores 420 points — and even that is hard, because your first instinct is almost always a Plankton answer.
What time does the daily Krillion reset?
Midnight US Eastern time (Washington, D.C.), which is 04:00 UTC during daylight saving time. Until then, the dive is the same for everyone; after it flips, yesterday’s prompts move to the archive and a fresh set goes live.
Is Krillion free?
The daily dive is free, with no signup required. An optional account keeps your streaks, history and friends features. The official FAQ notes that unlocking content in any themed pack disables ads across the whole site, and the game can be installed to your home screen as an app.
Who makes Krillion?
A solo developer — “No, just me,” per the official FAQ. Answer sheets are built by merging dictionaries, wikis and encyclopedias, with rarity judged by a word-frequency database plus manual review. The roadmap includes a native app, merch, multiplayer and a Krillion-based party game.
Where can I see past Krillion answers?
Right here: our Krillion archive lists every dive since day one — all 71 of them — with each prompt’s answers ranked by tier. Past dives can also be replayed in the official app via the Logbook and Unlimited.
What is KrillionHQ?
