Thanks to Julian for a deilghtful puzzle, and thanks to you for the excellent demo. Not surprisingly, I quickly abndoned the idea of playing my usual, notation free, game. I took a while to figure everything out, but finally did it.
Ver beautiful puzzle construction by Mr. Julian. I saw before one time same type of puzzle, it needed, corner solvation first, then border cells solvtion, after than inner cells solvation, but neeeded very advanced strategy. This puzzle also as same solvation. I tried my self to solve. Firstly Corner cells , Notable to do anything, because of both are 59, 79 pairs, eliminate no's in 9s in col 1& 9. Thats all. Than 2468 in four no's in four cells left and right sides,137 three no's in four cells, l am only focused with 137 sets and want to 7 any place. But failed. I made mistake to see XY wing, because of l thought 137 makes something. Than I dont want to go any hard way, than l left to solve, and saw the vedio. Yes, it is solved just by XY wing, and l saw your great highlight explanation in this puzzle. I expeted, and expecting this type beauty puzzles I enjoyed lot when you solving. The beauty puzzle, you made more beauty with your explanation. It helps in my future solve. Thankyou for giving un forgettable learning puzzle.
I started penciling cornermarks, and got a quick X-wing in 2s, unnecessary because of the Y-wing I found later. (I didn't know that at the time.) SET fills me with dread, and I hoped that I could bipass it. However, I got stuck, and my usual coping with being stuck would have swamped the grid with centermarks. One possible SET occurred to me -- the outer rows and columns, but I initially dismissed it. After trying a more complicated thing that got nowhere, I tried that one. One set was rows 1 and 9, the other was columns 1 and 9. Both rows gave me chocolate-teapot triples in the even numbers -- 246 and 248. It took some time before I spotted a Y-wing in the triples -- I suspect they had at least two Y-wings. One digit placement, and the triples melted. Following that, the puzzle gradually unwound. 1:10 So those were the sets you used -- the simplest SET application you've seen? 4:40 I had to backtrack and make sure I understood what you said about eliminating 9s from the columns. If you could place the 59 and 79 pairs in the corners, you have an X-wing in 9s.
Very nice John. I haven’t seen anything simpler than 2x2 SET application. The X-Wings, MSHS, and continuous loops would all work as well. I had quite a bit of fun with this one.
@@SmartHobbies Well I didn't exactly know about set. I did recognize the patterns and saw the numbers on the outsides. So I had a similar beginning with 79 on the corners, 246 in the top row, 59 on the bottom corners, and248 on the bottom row. But I got stuck and I watched the video to get the xy wing.
Great question. SET can be applied to any row or column. I’ve seen 4-5 rows assigned to one color and 4-5 columns assigned to the other. The key is look for given digits that offset as much as possible from one “color set” to the other and be predominately made up of different sets of digits themselves. This will create the restriction we are looking for. I cannot say there is a strict minimum, but usually you need at least 3 givens for each row/column when each color set contains 2 or 3 sets of the digits 1-9. I advise you watch more of the videos from my SET Tutorial playlist. I show many different types of SET setups to show you how versatile it can be. Hope that helps.
@@SmartHobbies Thank you and I will. I'm too the point where I need to move to more advanced solving options now. STE is very new and I'm still having a tough time recognizing the x-wings, xy wings etc

Nice revision of set theory.
Thank you. I enjoyed this puzzle from Julian quite a bit. I hope you did too.
Lots of fun. It was interesting to see how the 9's in the corners played out.
Glad you enjoyed it, Bruce. I had fun with this one as well. So many ways to approach it.

Great job, Georges.
I’m glad you enjoyed the puzzle by Julian.

Glad you enjoyed it. Did you try SET or something else to solve this puzzle?

Question, to use SET, do a certain amount of numbers need to be in the outer row for it to work or does it work no matter what is in those rows?
