Krillion Lexicon
Every Krillion term, tier and rule — from Daily Dive to One in a Krillion — explained with real examples from verified answer data.
Game Mechanics
- Prompt
- A single question or clue in a Daily Dive. Each prompt has a category tag (Geography, Food, Entertainment, etc.) and a difficulty level. You get one attempt per prompt, and your answer's rarity determines the points.
- Spoiler-Free
- The hints system on KrillionGuide reveals information progressively: category clues first, then first letters and word lengths, then more specific descriptions — without ever showing the actual answer. You decide how far up the ladder to climb.
- Verified Answer
- An answer confirmed by community trackers to have actually appeared in a Daily Dive with a specific rarity tier. KrillionGuide tracks {count, plural, one {# verified answer} other {# verified answers}} across every past dive. Unverified entries are always marked.
Game Modes
- Daily Dive
- The core game mode in Krillion: 7 prompts per day, one attempt each, 15–20 seconds per prompt. Your answers are scored by rarity — the fewer players who type the same word, the deeper it sinks and the more points you earn. A new Daily Dive resets every day at midnight UTC.
- Unlimited
- A free practice mode in Krillion with unlimited rounds and no risk to your Daily Dive score. Unlimited Classic and themed packs let you train your rarity instincts between daily dives. Play free in any browser, no download needed.
Rarity Tiers
- One in a Krillion
- The rarest rarity tier in Krillion, worth 100 points per answer. Fewer than 1% of players worldwide type these words — they are the legendary deep cuts that separate elite divers from the rest. Each Daily Dive has a handful of verified One in a Krillion answers.
- Plankton
- The lowest rarity tier in Krillion, worth 5 points (50 m). Plankton answers are the obvious picks that nearly every player types — the first thing that comes to mind. If your answer feels too easy, it is probably Plankton.
- Rarity Tiers
- The six scoring levels in Krillion: Plankton (5 pts), Too Clever (15 pts), Schooler (25 pts), Rare (50 pts), Deep Cut (75 pts) and One in a Krillion (100 pts). Each tier represents a different level of answer uniqueness.
- Schooler
- The third rarity tier, worth 25 points (250 m). Schooler answers are a step above obvious — they show some thought but are still fairly common among experienced players.
- Too Clever
- The 15-point rarity tier that punishes overthinking. Too Clever answers are the ones that feel like deep cuts but collide with thousands of other players who had the same clever idea. They score more than Plankton but far less than true rare answers.
Scoring
- Depth
- The scoring unit in Krillion. Every point you earn converts to 10 metres of depth. A 50-point answer sinks 500 m; a Perfect Dive (700 points) reaches the Trench Floor at 7,000 m. Depth determines your ocean zone at the end of each dive.
- Depth Zones
- Four ocean layers that classify your daily score: Sunlight Zone (0–1,000 m), Twilight Zone (1,000–2,500 m), Midnight Zone (2,500–5,000 m) and Trench Floor (5,000+ m). The deeper you go, the rarer your answers were.
- Perfect Dive
- Scoring 700 points in a single Daily Dive — the maximum possible if every answer hits the top tier. A Perfect Dive sinks you 7,000 m to the Trench Floor. It requires all 7 answers to land in the highest rarity brackets.
- Rare Answer
- An answer that fewer than 10% of players type for a given prompt. Rare answers earn 50+ points and sink you into the Midnight Zone or deeper. The rare answer finder tool lets you browse verified rare answers by tier.
- Rarity
- How uncommon your answer is compared to what other players typed for the same prompt. Rarity is the core scoring mechanic: common answers earn 5–15 points, while rare answers earn 50–100 points. The game tracks what percentage of players chose each answer.
- Score
- The total points earned across all 7 prompts in a Daily Dive. Each prompt contributes 5–100 points based on answer rarity. Scores convert to depth at 1 pt = 10 m. Use the score calculator to convert your 7 scores into depth and ocean zone.
- Trench Floor
- The deepest ocean zone in Krillion, reached at 5,000+ m depth. Only divers who score 500+ points in a Daily Dive reach the Trench Floor. A Perfect Dive (700 pts) sinks exactly 7,000 m — the theoretical maximum depth.
- Zero Score
- Three ways an answer scores zero in Krillion: (1) no attempt before the timer runs out, (2) an answer that does not match any accepted response for the prompt, or (3) certain edge cases where the game rejects the input. A zero earns 0 points and 0 m depth.
Strategy
- Specificity
- The strategy principle that specific answers beat generic ones. A generic answer like 'dog' scores Plankton; a specific one like 'basenji' scores Rare. Specificity is the single biggest lever for improving your daily score.
