What replay is (and isn't)

Replay re-serves a closed day's set — the same seven prompts, the same bank, the same 25-second clocks — under practice rules. Your score is real, your depth is real, and neither touches your daily record, your streak or your achievements' daily conditions. That separation is what keeps the daily honest: nobody can grind today's set in advance, because today's set is never in replay until it has closed for everyone.

The best use of replay is diagnostic. Dive a closed day, then open its published answers and compare, prompt by prompt: where did you stop — Plankton, Too Clever, Schooler — and what did the next tier down look like? Three replays a week of that comparison teach the crowd's shape faster than any guide, including our own strategy page. For fresh water rather than revisited water, Unlimited shuffles the whole bank with no date attached.
