How to Play Krillion

Seven prompts a day, one attempt, and a simple rule: common answers float, rare answers sink.

What is Krillion?

Krillion is a free daily trivia dive game. Every day, all players worldwide face the same 7 prompts and have roughly 15–20 seconds to type one answer per prompt. The twist: common answers float while rare answers sink — your score depends on how few people type the same word you do.

Core rules at a glance

  • 7 identical prompts per day, worldwide, same order.
  • About 15–20 seconds per prompt; a blank or timed-out answer scores 0.
  • 1 point = 10 metres of depth. 700 points = 7,000 m — the Trench Floor (Perfect Dive).
  • The Daily Dive allows exactly 1 attempt per day; for unlimited practice rounds, check the Unlimited mode.

💡 There is no penalty for a mediocre answer — only for an invalid one. A safe 30-point word beats a rejected 0.

Beginner tips

  • Specific beats general: "Axolotl" sinks far deeper than "Dog".
  • Typos sink dives: a misspelled word is rejected and scores 0.
  • The 10-second rhythm: spend 10 seconds climbing past your first two ideas, lock in pick #3 or #4, then spell carefully.

Your first dive, prompt by prompt

Reading rules is one thing; playing is another. Here is the realistic shape of a first dive, so nothing about the flow surprises you. Prompt 1 appears with its category tag and a 15–20 second timer. You type one answer — anything that fits the category — and the game immediately shows where it landed: the tier name and the metres it sank. That instant feedback is the tutorial. By prompt 3 you will have seen a Plankton (10 points) or a Too Clever (15 points) land, and the instinct to climb one rung further starts forming on its own. Prompts 4–7 are where the rhythm settles: climb for the first half of the timer, commit, spell carefully, submit. When the seventh answer lands, the game totals your points, converts them to depth and drops you into an ocean zone — that zone is your daily result, and the whole worldwide player pool gets the same seven prompts to compare against.

  • The tier reveal after each answer is information, not judgment — it teaches you what the crowd is typing today.
  • Depth zones are the scoreboard: Sunlight (0–200 m) is the crowd, Midnight (1,000–4,000 m) is where disciplined ladders land.
  • One attempt per prompt is final — but the whole dive resets tomorrow, so a bad day costs nothing but the day itself.

What counts as a valid answer

The game accepts answers through a curated word list per prompt, which is why validity and rarity are separate judgments. A word can be rare because nobody types it — or "rare" because nobody typed it because it is not on the list. Accepted lists are generous with proper nouns (cities, species, brands, characters) and strict about spelling: a one-letter typo is not a near-miss, it is a zero. When you are torn between a risky deep cut and a safe mid-tier word, the deciding question is not "is it rare" but "am I certain of every letter". A 60-point Rare you can spell beats a hypothetical 100 every time.

  • Proper nouns are usually valid — named places, species, brands, fictional characters.
  • Spelling is binary: accepted or zero. No partial credit, no suggestions.
  • Category fit is checked: a valid word outside the prompt's category scores 0.

Frequently asked questions

▸How do you play Krillion?

Krillion is a free daily trivia game. Every day you face the same 7 prompts and have 15–20 seconds per prompt to type one answer. Common answers score low (10 points), rare answers score high (up to 100 points), and you get exactly one attempt per prompt per day. Play at krillion.io in any browser — no download or account required.

▸How does Krillion scoring work?

Each answer lands in one of six rarity tiers based on how many other players worldwide typed the same word. Plankton (10 pts) is the most common; Schooler (30 pts) is mid; Too Clever (15 pts) is the collision trap for overthought picks; Rare (60), Deep Cut (85) and One in a Krillion (100) reward genuinely obscure answers. Every point equals 10 metres of depth — 700 points is the 7,000 m Perfect Dive.

▸When does the Krillion Daily Dive reset?

The new Daily Dive goes live around 12:30 a.m. US Eastern time (04:30 UTC during daylight saving, 05:30 UTC in winter). That is one dive per calendar day; miss it and that day is gone for your score, though you can replay every past dive in the archive for practice.

▸Is Krillion free? Do I need to download anything?

Yes, Krillion is completely free and runs in any modern browser — no download, no account, no install. The Daily Dive is free, and unlimited practice rounds are available in Unlimited mode. It works unblocked on school and work networks since it is a browser-only site at krillion.io.

▸What happens if I miss a day or score zero on a prompt?

Nothing carries over negatively. A timed-out or invalid prompt scores 0 for that prompt only — the rest of your dive still counts. Miss a whole day and that day's dive is simply gone for your record; there is no streak penalty and no way to replay it for score, though the archive lets you practice every past dive for free.

▸How is my daily result measured?

Your seven prompt scores add up to a total between 0 and 700 points, and every point converts to 10 metres of depth. The depth places you in an ocean zone — from the Sunlight Zone near the surface to the Trench Floor at 7,000 metres, which only a Perfect Dive (seven 100-point answers) reaches.
