Need help on this one...

I think this one is hard. I can't find anymore numbers. I was told that there was a some kind of locked candidate in this one, but I don't know what that is...

Here is a partial answer to your question.

Re locked candidates:

Look at boxes 2,5,8 with the number 5.
Look to the columns, where can't the 5 go.
Some eliminations can be made.

Then look at boxes 3,6,9 with the number 6.
Again, look to the columns.
Some eliminations can be made.

Once elimination's have been made you should find a naked pair in row 8 allowing you to eliminate some candidates.

This leaves a naked quad in box 7, again some eliminations can be made.

That's as far as I have got so far.

Hey killing spree – I spent quite a lot of my day off on your puzzle - thanks!:) - and I’m wondering how you got on with it. I found locked candidates, naked pairs, Xwings and a swordfish but I’m still stuck (but I haven’t given up yet!)

PS : It’s called ‘arguably unfair’ in the Pappacom solver.

PPS : You kids do hard puzzles!
