Sudoku Primer 137 - subscriber request (double row/col elimination)

Subscriber Gary McIntosh, thank you for your request. A diabolical puzzle from Sudoku To Go volume 117.

In this puzzle we hit one place where the going gets tough. At that time we need to use a combination of techniques, mostly double row and column elimination.

See video 124 https://youtu.be/nX55wcXyRrI for a good explanation of double row/col elimination.

You can go to www.sudokuprimer.com for sudoku tips and techniques. There is also a video index listing all of the videos on this channel.
