Completion Times

Puzzle difficulty as measured by time taken by the 100th person on the global leader board to complete each puzzle.

Frequency distributions of times for the first 1000 stars of each colour. Times, on the horizontal axis, are in seconds on a log scale. As a guide, 256s = ~4min; 2048s = ~30mins; 32768s = ~9hrs and the right hand side is ~4 days.
