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, show broken inequalities and 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.
