How to Play Krillion

The whole game in one sentence: seven open prompts, one typed answer each, 25 seconds per prompt, and depth awarded by how uncommon your correct answer is. Everything below is detail.

Free · unlimited7 prompts · 6 tiers · 9 depth zones

The 60-second version

  1. Read the prompt. It is always an open question with many correct answers.
  2. Type one answer. Only one per prompt, and it has to be correct.
  3. Get graded by rarity. The bank already knows which accepted answers players type most.
  4. Convert to depth. Points × 10 = metres. Seven prompts, maximum 7,000 m.
  5. Dive again. No daily limit, no cooldown, no fee.

A dive, step by step

Tap Begin descent on the home page. Seven prompts are dealt from a bank of 60, spread across eight categories. The first prompt appears with a 25-second countdown. Type an answer and press Sink — or press Enter. The game normalises what you typed, checks it against the accepted list, and shows the tier and points immediately. Then the next prompt arrives.

After the seventh answer the results screen shows your total depth, the ocean zone it falls in, and a list of every prompt with your answer and its points. Anything the bank did not accept is marked. From there you can dive again immediately or share the result. The whole loop is designed to take three minutes.

Scoring: six rarity tiers

Every accepted answer belongs to one tier. The tier is set by how crowded the answer is in the bank, never by your typing speed. The six tiers and their values:

TierPointsDepthWhat it means
Plankton10100 mThe answer everyone gave
Too Clever15150 mA sideways step, still crowded
Schooler30300 mA real move away from the crowd
Rare60600 mGenuinely uncommon
Deep Cut85850 mVery few divers found this one
Deepest1001,000 mThe one in a krillion answer

The top tier is Deepest. Every prompt in the bank has at least one Deepest answer, so a perfect dive is possible on any set. In practice, most dives land between 1,000 and 4,000 metres.

How depth works

Depth is just points made visible: one point equals ten metres. Seven Plankton answers make 700 metres; seven Deepest answers make 7,000. The results screen maps your total onto nine ocean zones so the number has a shape:

ZoneDepth bandWhat it takes
Sunlit Shallows0–150 mA steady, surface-level dive
Coral Garden150–350 mA steady, surface-level dive
Kelp Cathedral350–600 mA few strong answers
Reef Wall600–900 mA few strong answers
Twilight Edge900–1,400 mMost of the dive lands rare
Deep Blue1,400–2,200 mMost of the dive lands rare
Midnight Zone2,200–4,000 mDeep cuts on several prompts
Abyssal Plain4,000–6,000 mNear-perfect rarity across all seven
Hadal Trench6,000–7,000 mNear-perfect rarity across all seven

Around 4,000 metres is a strong dive. Reaching 6,000 metres means most of your answers were Deep Cuts or better. The trench floor at 7,000 requires seven Deepest answers in one dive.

Words the game uses

The game keeps a small vocabulary. Six of the words below are the rarity tiers; the rest describe how a dive works.

PromptThe open question a turn asks. You get one typed answer per prompt
DiveOne full game: seven prompts, 25 seconds each. Total depth is the score
SinkWhat a good answer does. Points become depth at ten metres per point
Plankton10 points, 100 m. The answer everyone gave
Too Clever15 points, 150 m. The sideways answer many players reach for
Schooler30 points, 300 m. A real move away from the crowd
Rare60 points, 600 m. Genuinely uncommon
Deep Cut85 points, 850 m. Very few divers found this one
Deepest100 points, 1,000 m. The rarest accepted answer on the prompt
BankThe game's prompts and hand graded answers, grown by hand

Classic and Zen

Classic mode gives each prompt 25 seconds; when the clock hits zero, whatever is in the box is submitted. Zen mode removes the countdown entirely. The scoring is identical in both, and so is the results screen. Choose Zen if you want to think, or if you are playing somewhere a ticking clock is unwelcome.

Answer matching and aliases

Matching ignores capitalisation, accents, punctuation and leading articles. Each answer also carries aliases for the names people actually type: “UK” for United Kingdom, “USA” for United States, “Man Utd” for Manchester United, “8 1/2” for 8½. A clear, conventional short form will usually be accepted; a genuinely different name will not.

If an answer is correct but missing, the results screen marks it and the contact page takes the suggestion. Suggestions are checked by hand: a wrong answer never enters the bank, and a right one is graded before it is added.

Playing a friend

A duel fixes the seven prompts with a code so two players face the same set. Generate a code on the 1v1 page, send the link, and both players play on their own device. The higher total depth wins; a tie is broken by the deeper single answer. Duels are asynchronous, so nobody has to wait in a lobby.

Four mistakes that cost depth

  • Typing the first answer. It is the crowded one by definition. Bin it once and look again.
  • Trying to be clever. The “smart” alternative is usually still in the Too Clever tier. Go sideways, not louder.
  • Leaving the prompt. A rare answer still has to be correct. A wild guess is zero points, not a lottery ticket.
  • Skipping the results. The list of accepted answers on the results screen is the cheapest study material in the game.

Rules: frequently asked questions

How long is a dive?

Seven prompts. In Classic mode each prompt gets 25 seconds, so the clock time is under three minutes; in Zen mode there is no clock and a dive takes as long as you want. A dive ends after the seventh answer and shows your total depth.

What is the maximum depth?

7,000 metres. Seven Deepest answers at 100 points each make 700 points, and one point equals ten metres. That is the floor of the Hadal Trench and the top of the depth scale.

Does typing faster score more?

No. The tier is a property of the answer you gave, not of how quickly you gave it. A Plankton answer typed in one second and a Plankton answer typed in twenty are worth the same ten points. The clock only decides whether you get an answer in at all.

What is Zen mode?

The same dive with no countdown. Every prompt is still worth the same points, and the results screen is identical. Zen exists for players who want to think, or who are playing on a device where a timer is more stressful than fun.

Why was my correct answer not accepted?

The bank accepts a fixed list of answers and aliases per prompt. A valid answer can miss if it uses a different name, a different spelling that is not in the alias list, or a correct example that has not been graded yet. The results screen marks the miss; the contact page takes suggestions.

Do I need an account to keep my score?

No. Your best depth, average and dive count live in your browser storage. They survive a refresh and a browser restart, but they do not follow you between devices, and clearing site data resets them.

How do I play a friend?

Use the 1v1 page to generate a duel code. The code fixes seven prompts; send the link and both players play the same set on their own device, then compare total depth. No account and no live room are needed.
