Fours in column 1 and 5 allow elmination of other fours and solves the puzzle.

When I try to use what looks like a perfectly good x-wing on 8 in c67 the puzzle goes bust. Could someone help me out here?

Rocky; this is a very good puzzle. The key for me was getting to the point that revealed the 456 XY-wing by using the 8 Xwing, the 345 trip followed by the 46 pair. After that I used a bunch of pairs, trips, and quads to the solution. When I solve a puzzle I tend to play in the order I see things so I'm not always sure I'm taking the shortest way to the solution. I have a feeling there are other paths to take.

Actually, I did have it. Just for kicks I pushed the "Grade" button and it's response was "Too Hard", hence my last post. I started over, when I filled in after the 8 x-wing in c68 I tried grade again, again I got "Too Hard". This time I ignored it and went on to solve the puzzle. Lesson learned. Good puzzle!

I too found the strange occurrence of 'Too Hard' which usually means you've
gone wrong- but in this case it's obviously a programming xx.
