Yes, it is fairly difficult. And it can be solved without brute force.
Can people confirm that this one can be classed as "difficult" ?
I have been trying to solve this on and off for the past few days. I’ve spent loads of time on it and I remain stumped. So I would definitely class it as difficult!

Has anyone actually solved it?
Spent another hour or so on it today. Still stumped!
