Friday Puzzles #175
Sometimes it's handy having 40+ minutes of a competition round to sit in silence when you want to make a puzzle. As with the majority of my sudoku, this one is pretty easy despite having no clued 9's. If you are playing the speed solving game, less than 3 minutes is good, less than 2 minutes is very good and 90 seconds is probably world leading. Enjoy!

ReplyDeleteI remember this puzzle... Discussing the uniqueness after the finals!!
ReplyDeleteHaha yeah, stubborn fool that I was I decided the best thing was to tweak some of the existing givens rather than add a few extra ones. I guess it kind of changed the puzzle a little bit, but I'm surprised no-one has broken 2 minutes on it just yet!
ReplyDelete1'46, with a bad method. I think the 90" mark is reachable indeed... but not by me this evening.
