Krillion

Krillion is a clever daily web trivia game that completely flips standard quizzes on their head. Instead of picking answers from a boring multiple-choice list, you embark on a “Daily Dive” where you face seven open-ended category prompts with a 25-second oxygen timer on each one. The game features a retro CRT terminal look and a fun underwater theme where your guesses propel a tiny krill diver down into the deep sea. Because a full expedition takes only a couple of minutes and plays straight in your browser with zero downloads, it is the perfect mental warm-up to play between classes or during a quick study break.

What makes the game so thrilling is the reverse-trivia scoring system where the rarest valid answers plunge you the deepest. If you type the first thing that pops into your head, like “Chrome” when asked to name a web browser, the sonar registers you as basic Plankton and only gives you 100 meters. But if you dig deep into your memory for an obscure answer, you can score a Deep Cut or trigger the legendary “One in a Krillion” rating for a massive 1,000-meter drop. You dive through five distinct ocean zones, starting from the Sunlit Zone at the surface all the way down past the pitch-black Abyssal waters into the Hadal Trench.
