Completed in one session without solving aids
Times marked * had very minor assistance

All other times
Time marked ^ solved in one session without 'show wrong'

All times above completed without any aids and without 'Check solution' when wrong or incomplete, except times marked '*' which had very minor assistance by using no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or used highlighting aids (show repeated digits [except for hitori where this counts as a major aid], show broken inequalities, or show valid/invalid placements [slitherlink] only) Times marked '^' were completed in one session with use of solving assistants or use of 'Check solution' more than once when wrong and/or incomplete. All other times used 'show wrong' or were completed over multiple sessions, which is potentially a significant aid.
