Choose your question count
Before you start, choose any multiple of 7 from 7 to 168. Seven questions is the default and a good way to learn the rules. Choose 14 or 21 to practice across more categories. The game ends after the number of questions you picked, even if you miss some.
How long a dive takes
Each question gives you 3 seconds to read the prompt and up to 25 seconds to answer. If you use the full timer, that is 3 minutes 16 seconds for 7 questions, 6 minutes 32 seconds for 14, 9 minutes 48 seconds for 21, and 1 hour 18 minutes 24 seconds for 168. This counts only reading and answering. Animations, time between questions, pauses and reviewing your results can make the full session longer.
See an accepted answer after a miss
A wrong answer or a timeout without a valid answer earns zero points. The game shows one accepted answer as an example, then advances automatically. A miss uses up one question in your chosen total. After the final question, you surface and see your results.
Read your score and review the answers
Accepted answers earn 10, 15, 30, 60, 85 or 100 points based on the rarity tier assigned in the question pack. Each point adds 10 metres of depth. On the results screen, expand a question to compare your answer and points with other accepted answers. For a long dive, use the page controls to review earlier questions.
Save your dive and return later
Choose Save and exit in the game menu. To continue, open Custom Question Count again in the same browser profile. The run is stored on the server and tied to this browser, so switching browsers or devices, or clearing site data, can leave you without access to the saved dive. Krillion does not use an account or offer cross-device cloud sync. Custom Question Count and Unlimited Mode have separate saves.
