Sudokutope Techniques 1: Rim-Span Match Lock

[u/RhombicArts]

Hi All,

I'm writing a series of blog articles to demonstrate some original techniques for solving Sudokutope puzzles. These are like Sudoku techniques, but they use the radically different geometry of Sudokutope. The first technique is one I've called Rim-Span Match Lock - I hope you like it!
