suppose the random number is 169 and you enter 999 it says matches all digits but that's wrong. becuase n1, n2, n3 matches g3 Your conditions are only checking if the numbers are matched with every other number. they are not restricting that one number has been checked and need not to be checked again. like if n1 matches g3; these numbers are locked and g3 must not be checked against n2 or n3

I actually do not know the answer to this and that is how I stumbled upon your repository. might update you if I can come up with a solution.
