Make the most of Krillion practice
Mixed practice draws across all four subjects. A strong round in a familiar category can sit next to a prompt that sends you somewhere new. Treat that variety as an invitation to explore, and use the themed pools when you want to concentrate on one area.
A complete dive in seven rounds
Read for three seconds, then answer within twenty. An accepted name ends the round. If a name is not recognized, you can retry while time remains. A skip or timeout scores zero, and Next starts the following preview when you are ready.
Familiarity becomes depth
Krillion awards 10, 15, 30, 60, 85 or 100 points per accepted answer, with ten metres for each point. The tiers are editorial estimates, not live player frequencies. Seven top-tier answers reach 7,000 metres; there is no speed bonus.
Finish the current dive before starting another. Each pool reserves seven questions at the start and avoids repeating them until its cycle is used. An unfinished dive resumes; refreshing does not produce a fresh set or reset the timer. Changing themes uses a separate pool history.
