I found today’s 7x7 particularly difficult. It took several attempts to solve it and I note that there have been relatively few solvers so far for a non subscriber only puzzle of this size. It will be interesting to see how many people in total manage to solve it.

I agree. After several seemingly sensible trials got me to error or stuck, a lucky guess got me through.

Thanks to Paul’s warning, I didnt waste to much time doing on an analytical solution, I went to brute force (trail and error). I was lucky and it only took a few tries.
