Krillion Game is a browser-based trivia game built around one simple idea: give the rarest correct answer. Instead of rewarding the answer most people know, Krillion gives more points when fewer players would think of the same response.
In Krillion Unlimited, each dive features seven open-ended prompts, with 25 seconds to answer each one. Your score becomes an ocean depth, with every point sending you 10 metres deeper. Common answers barely move you, while a “One in a Krillion” answer earns 100 points and sends you down 1,000 metres.
A prompt can have many valid answers, but they are not worth the same. Your goal is to move past the obvious response and find something more specific or unusual.
Every accepted answer falls into one of six rarity levels based on how many other players would give the same response. The rarer the answer, the deeper you descend.
A perfect seven-question dive earns 700 points, taking you to 7,000 metres. The challenge is not simply finding a difficult answer—it is finding one that is both correct and uncommon.
Krillion Unlimited also offers Endless mode, where prompts continue one at a time with three tanks of air. A miss costs one tank, while a “One in a Krillion” answer restores one.
Krillion uses simple browser controls, so there is no complicated control scheme to learn.
Multiplayer supports rooms of up to 30 players. Everyone receives the same prompt simultaneously, then sees the answers and scores after each round.
The key to Krillion is simple: be correct, but try not to think like everyone else.
The name Krillion is a playful combination of “krill” and the invented number suffix found in words such as “million,” “zillion,” and “gazillion.” It connects to the phrase “one in a krillion,” which describes something extremely rare.
The idea also fits the game's central mechanic. Krill often gather in enormous swarms, while the Krillion game rewards the answer that stands apart from the crowd. In other words, being “one in a krillion” means coming up with the response almost nobody else reaches.
