Here is A code that I left out of my original post that worked for me today.

Code: 50PLAYDAY

This $50 ND code also works at these two casinos:

Planet7 Casino
and
CatsEye Casino

I read this at another forum. I had my doubts on it working but sure enough, it worked like A charm! I would have sworn that I tried it already and was denied.
Perhaps I had got a space character in my code by accident. Anyway they do work!
