I honestly can't tell if I think this is a good puzzle or a bad one. It's clear it has an absurdly narrow entry. I've got one digit, I've found about 180 equivalencies, and I haven't moved in about 2 hours.
[Edit] I did finally get this solved after about 4 hrs. It really feels like this needs bifurcation to make happen. I'm sure there is a more logical path, but I couldn't find it, and eventually you have to give up.
I definitely agree with DiMono, this is a 5-star difficulty.
