As it would turn out, there is more strategy to SuDoku than I imagined. Had I taken a mere moment to browse the subject on the world wide web, I’d no doubt have learned this. But, alas, I did not. Until yesterday. I have now learned that one should not have to resort to trial and error, but solve the puzzle with logic alone. (I did finish that 12×12, but sadly, used trial and error and a careful mapping scheme. It took four tries, I’m embarrassed, yet also pleased, to admit.)
I was far too rusty in my knowledge of permutations, but now, now I am equipped with the x-wing and the swordfish. I cannot be stopped! Onward ho!
(I plan to tackle one 16×16, armed with my new arsenal of techniques, and, upon completion, will move on to better and more productive diversions.)
As if I have time for diversions. Of any sort.
My SuDoku journey has been an indulgence.
