What Is Noillirk?

The short definition

Noillirk (say it: noy-LIRK, or just read it in a mirror) is a rarity game. Each day it poses seven prompts — "Name a European capital", "Name a fermented food", "Name an animal with tentacles". You answer each one against a 25-second clock. But Noillirk doesn't grade correctness; it grades uniqueness. Every possible answer the game expects has been pre-scored by how many players would give it. The obvious answer scores 10. The rarest scores 100. Your total becomes a dive: points convert to ocean depth, and a perfect game — 700 points — reaches the trench floor at 7,000 metres.

It is free, it needs no account, it runs in a browser, and one dive takes under three minutes. Yesterday's answers are published daily; today's are yours to earn.

Why "backwards"? The name is the mechanic

KRILLION read backwards is NOILLIRK. The reversal is not decoration — it describes the skill the game measures. Ordinary trivia asks: what do you know? Noillirk asks a question that runs the other way: what does everyone else know, and where does their knowledge stop? To score, you mentally reverse the room: picture a thousand players meeting the prompt "Name a country with Z in its name". A thousand keyboards type Zambia. The backwards thinker sees the crowd's answer first, rejects it, and keeps swimming — past Czechia, past Kazakhstan — to Kyrgyzstan and the 100-point tier named after this site: One in a Noillirk.

Psychologists call the underlying ability perspective-taking — modelling other minds. Game theorists meet it in Keynes's famous beauty contest, where the winning move is to predict the predictors. Noillirk is that contest miniaturised into a daily ritual: seven little elections where the winning answer is the one almost nobody votes for.

The pieces of the game

• The bank. 302 prompts across eight categories — geography, movies, sports, food, science, animals, history and music — each with its expected answers pre-scored into six tiers: Plankton (10), Too Clever (15), Schooler (30), Rare (60), Deep Cut (85) and One in a Noillirk (100). The bank is the crowd, written down.
• The daily dive. One shared set of seven prompts per day, resetting at midnight UTC, one attempt per player. Streaks and achievements ride on it. It is the ritual the site is organised around.
• The depth. Ten metres per point, drawn to real ocean scale: you pass the twilight zone, the deepest scuba dive ever, the Titanic's rest, and the hadal dark on your way to the floor.
• The other modes. Unlimited (endless shuffled dives), eight category Packs for deliberate training, Challenge (a pass-and-play duel on one device), Replay and an Archive that publishes every day's full answer bank the morning after.
• The mirror ranks. Your total is read back as a rank — Surface Reflection, Glass Reef, Mirror Deep, Reverse Current, True Noillirk — a small ceremony that tells you how backwards you thought today.

Where it sits among word games

Noillirk belongs to the daily-game family — one short shared challenge a day, built for streaks and for arguing about over coffee — but it is not a spelling game, a guessing game or a trivia quiz in the usual sense. Its closest relatives are the rarity and reverse traditions: games where the least-given answer wins (the "pointless" format popularised on television), and the backwards wordplay lineage of palindromes and semordnilaps — words like racecar that survive reversal, and pairs like stressed/desserts that reverse into each other. The site keeps a whole wing for that lineage: the backwards word game guide and a field guide to palindromes.

And its name places it in one more family: the mirror. Noillirk is the reversed twin of the rarity dive Krillion — same rules, violet water, the thinking flipped. Players who go looking for a "reverse Krillion" or "opposite Krillion" game are, knowingly or not, spelling this site's name. That story is told here.

Noillirk vs Krillion: the mirror, side by side

Players who know the original rarity dive ask what actually changes in the mirror. Less than you'd think — and all of it deliberate:

• The name flips. Krillion forwards, Noillirk backwards — a true semordnilap pair, like stressed and desserts.
• The water changes colour. The mirror world runs violet: dusk light, purple glow, a surface like glass. Same ocean, other side of it.
• The crown is renamed. The rarest answer here is not "one in a krillion" — it is One in a Noillirk, exactly one banked per prompt, worth the same 100.
• The ranks speak mirror. Totals are read back as Surface Reflection, Glass Reef, Mirror Deep, Reverse Current and True Noillirk — a reflection of the dive, not just a number.
• The thinking is the game. Where a forward game rewards what you know, the mirror foregrounds its method: picture the crowd, reject its first answer, and dive for the one it never reaches.
• Everything else is shared DNA. Seven prompts, 25 seconds, six tiers, ten metres per point, one daily dive at midnight UTC. The mirror is a twin, not a parody — the full comparison lives on the reverse Krillion page.

The name, letter by letter

Read it slowly: N-O-I-L-L-I-R-K. Now read Krillion backwards and watch the same letters arrive in reverse order. Wordplay has a small, devoted vocabulary for this. A palindrome survives reversal unchanged — racecar, level, noon. A semordnilap (itself "palindromes" reversed) becomes a different word: stressed hides desserts, drawer hides reward, lived hides devil. Coined names almost never form clean semordnilaps — which is precisely why this one works as a brand: the reversal is exact, pronounceable, and impossible to unsee once noticed.

Say it either way you like — noy-LIRK, or simply "Krillion, read in the mirror." The site answers to both, and keeps a whole cabinet of reversible words for the curious: start with the palindromes field guide and the backwards word game — the family this name, and this game, grew out of.

What it is not

Noillirk is an independent fan game. It is not affiliated with krillion.io or any other rarity game; it sells nothing, has no accounts, takes no payments and stores your records only on your own device. It is not a test you can fail — a dive of pure Plankton still surfaces, still counts the day, still teaches you where the crowd lives. Tomorrow the mirror resets, and the crowd will be just as predictable, and you will be one day better at thinking backwards than you were today.
