What kind of game is Krillion?
Krillion ("the daily dive") is a daily rare-answer trivia game with an ocean-diving theme: per its official homepage, each daily dive is 7 prompts, 25 seconds each, everyone worldwide gets the same seven, rarer answers score big while obvious ones "float", every point sinks you 10 metres (700 points — the maximum — reaches the trench), and you get one dive per day, no second chances. Its official FAQ adds that answer sets are built by aggregating dictionaries, wikis and encyclopedias, with rarity scored against a word-familiarity database (some questions with LLM assistance plus a manual pass), plus alias matching for near-miss spellings. Beyond the daily dive it offers Unlimited (classic), Archive and Themed packs, and a Friends section. We link the official site so you can verify everything yourself.
Krillion vs Outlier Duel, honestly
Both games reward uncommon correct answers. The Krillion column below reflects the official homepage and FAQ as of 2026-10-12 — no invented specs.
| Krillion (official) | Outlier Duel (this site) | |
|---|---|---|
| Format | Daily dive: 7 prompts × 25 seconds; rarer answers sink deeper; every point = 10 metres of depth | Five rounds × 30 seconds per game; server-timed (refreshing never buys time) |
| Question count | 7 per daily dive (same for everyone) | Always exactly 5, drawn from a 30-question reviewed bank |
| How rarity is scored | Word-familiarity database scoring, some LLM + manual passes, per the official FAQ; max 700 ("the trench") | Editorial weights (20/40/60/80/100) per answer, assigned at review time with published sources and rationales; max 500 — explicitly not population statistics |
| Daily attempts | One dive per day, no second chances (official rule) | Daily set is frozen once per UTC day; replays are allowed and each session scores separately |
| Unlimited mode | Yes — "Unlimited (classic)" | Yes — every game draws a fresh five from the reviewed bank; play unlimited free |
| Friend challenge | Friends section exists (mechanics not detailed on the homepage) | Asynchronous same-set duels: your friend plays your exact five, answers unlock round by round only after they submit theirs, duel points decide the winner, one-tap rematch |
| Accounts | "My Krillion" page suggests an account system | No accounts ever — anonymous sessions, one cookie to survive refresh |

What makes Outlier Duel different
- An original five-round format. Short sets — five prompts, one sit-down, a score out of 500. The daily set is frozen once per UTC day, so everyone worldwide plays the same five.
- Editor-reviewed rarity scoring. Every answer's points (20–100) are chosen by content reviewers with a written rationale and a verifiable source. We publish the scoring philosophy on our scoring page — no black box.
- Same-question friend duels. Challenge a friend and they play your exact five prompts. It's a fair fight: identical questions, identical answer bank.
- Per-round reveal. Your answers unlock one round at a time, only after your friend has locked in theirs — then a duel-point verdict and a one-tap rematch.
- Server-authoritative and refresh-safe. Scores, timers and anti-cheat checks run on our server (Cloudflare Workers), not the browser.
