Your first seven answers
Read the condition and type one matching English answer. Press Enter or Submit; one valid answer completes the round. You have 25 seconds after a brief ready cue. Accepted aliases count. Submit again to confirm a spelling suggestion; an invalid answer lets you try again while the clock runs.
A whole ocean to explore
70 independently written prompts cover chemistry, US states, astronomy, calendars, NATO code words, mathematics, chess and SI units. Every question has a bounded answer set. Numeric answers also accept English number words. Review the complete answer set after your seventh round.
Designed depth rewards
Answers score 10, 15, 30, 60, 85 or 100 points. Scores are preset game rewards, not measured answer popularity. Review all answers and their points after seven rounds, then try for a deeper dive.
Daily or practice?
The daily dive resets at midnight New York time for everyone. One daily result per anonymous diver. The 70 prompts form a ten-day cycle. Practice follows a separate shuffled deck for your diver: all 70 prompts appear before the deck repeats. Daily records stay untouched.
Leaving and returning
Refreshing restores your round, not a fresh clock. Clocks keep running in the background and while disconnected. Practice can pause in a menu; daily challenges cannot. If the connection fails, reconnect and use Retry connection. Saved answers are never counted twice.
