Average difficulty rating - show wrong or multiple sessions
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
Here we have a section at the top with horizontal numbers 9+33+14+10 = 66.
If you add up the numbers for the vertical clues of those cells of that area, you get more - that is the bottom digit of the 22.
Do the same with the top cell of the 18 in the bottom area.
Always works, if there is an enclosed area with one or two cells "sticking out".
For example, in this puzzle, the 37 vertical clue is 8 short of 45, so it's missing either '1,2 & 5' or '1,3, & 4'.
In either case, we know it doesn't have a '1', so the the horizontal 4 clue resolves to [3,1] which tells us that the missing digits have to be '1, 2 & 5'
