Lesson #15: This sudoku strategy is a type of Turbo Fish and is useful in solving hard sudoku puzzles. You will find it pops up a lot, so its a useful pattern to learn. I hope you enjoy, thanks for watching!
@@LearnSomethingNewEveryDay I agree with Ken. Your examples, and clarifications really mean a lot to me, because they explain what we don't need to worry about. I appreciate that you tell us what to look for.
I'd like to see a video breaking down the order of operations of which techniques to look for in which order ( i.e. skyscraper, x wing, 2 string kite, naked and hidden triplets, x-y wings, etc.) Which techniques are "staples" and which are more esoteric and reserved for extreme puzzles?
You should use the given digits to solve the easy cells first. Start at 1, then go to 9. Repeat until you can go all the way through with no more progress. Next, go find the naked sets of 2 or 3. After that, look for chains and links. After that, find any hidden sets of 2 or 3. The rest has to be taken as you find them. I think that this is best.
I don't see why the strong link in column 4 (8-6) was not considered in this example forming a weak link in the bottom center box as well, thus eliminating the 5 in 8C.
Summary *Some term abbreviations for brevity* V = Vertical conjugate pair H = Horizontal conjugate pair H1 and H2 refer arbitrarily to the two points in the pair, likewise for V1 and V2. H1 & V1 meet in the same square, H1 ≠ V1. Intersection of H2 & V2 can elim. that num as a candidate
