You still didn’t explain how it works. Explain it from the point of view where the user knows only, and only the basic rule, 1-9 in the lines and boxes. Explain it better!!!
this is a quite good strategy!
You didn’t really answer the question or reolve the issue.. So where does the “two” go, without going through whole puzzle and solving it??
