martint Rated puzzle: Easy Best completion time: 8:31 Time on first attempt: 43:12 Used 'show wrong moves'
I got very stuck half way through till I noticed that the entire puzzle seemed to be the triples (369), (572), and (814) repeated.over and over. I spent a couple of minutes wondering if I could prove logically that the rest of the puzzle had to follow. I was not able to - though I will think more of it later.

However, I assumed that it was so repeated, and finished it very quickly.

joshuazucker Rated puzzle: Moderate Completion time: 7:12
I don't know if I can prove that at the beginning, either, but in the middle I could look at the 3s and 4s to get everything sorted.

Still working on that proof -- I know it's not true of nonconsec puzzles in general, so I don't know what to uncover in the givens to figure out whether the solution will have that type of pattern to it. Almost all (all?) of the puzzles in this set seem to have that pattern, which is a bit disappointing.

If enough rows fit the pattern, I can prove that the rest do, in that part of the puzzle at least. However, sometimes such a pattern only covers a small part of it, so it is possible to assume the pattern when it is not there.

  • 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'.
