Only boards finished with no hints are counted here, at the board you have chosen above. A hint makes a move for you. A board played with one is not the same board. The time is yours to beat and says nothing about your intelligence.

- Median time
Every finished puzzle is counted anonymously at its settings, with nothing that identifies who played it. Puzzles solved with a hint or a shown solution are counted but left out here, so every round here was solved without help and they compare on time. The spread and the median time appear once there are 30 rounds, and where your latest solve falls once there are 100.
Community comparisons appear once enough matching results are collected.
Only solved rounds are included. A round you leave before it is solved is not saved. Solving time counts the round on the screen, not background tabs.
Statistics use the latest 100 saved activities. Earlier rotation-only history remains stored separately. View all activity
