Play a round to start your log.
A level is cleared after two rounds in a row with at least 5 of 6 right, or the same share of a longer round, and no hint or shown answer. Tempo is the seconds per answer, and the best tempo counts only those rounds.

Community comparison
Rounds using hints or revealed solutions are excluded. One latest round per guest browser, at the same settings, in the last 90 days. Guest browsers are not verified people. Scores are self-reported, not a measure of intelligence.
Community comparisons appear once enough matching results are collected.
Only completed three-puzzle rounds are included. Revealed puzzles do not count as solved. Hinted and revealed rounds remain in your history but stay out of community comparisons. Active time excludes completed-puzzle reviews, pauses and background tabs.
Statistics use the latest 100 saved activities. Earlier rotation-only history remains stored separately. View all activity

Guest settings
Off until you choose. When enabled, future rounds send scores, settings, active time and task counts to Studio AM with a random guest ID for community comparisons. No individual answers, drawings or names. Earlier results stay local. This does not enable usage logging or advertising.
