As I understood "cuss" is not valid answer as far as it has two letters 's' and we have rule
a valid response word must contain four different letters

So probably it should stop execution somewhere on previous steps fo the game

Good day, trying to solve it with C# but every time some random test constantly fails without obvious reason. Could you please check this output?
