Intermediate problem - need coaching

Postby Mallycat » Sun Feb 26, 2017 1:23 am

Hi, newbie to the forum here. I would appreciate some help with this "hard" Sudoku

I have it down to the last leg and can't find a logical next move. I don't see any X Wing but am suspicious there may be a sword fish - but I can't see it (I've never ever found one and am looking to take the next step in my game.

I would appreciate any help.

This is a very complex puzzle by newspaper standards.

There is a Unique Rectangle type 4, but it doesn't get you anywhere. Better to go for the W-Wing. You can learn more about W-Wings here.

Thanks JasonLion

It took me a while to find it, but find it I did. It is one of those things that you need to experience. I was not aware of a W wing pattern - hopefully I can remember it for next time.

Appreciate your help
