Solve the alphametic part of the course challenge

OK! Let’s get down to the course challenge. Try and solve the following cryptarithm: I x KINGJO = JOKING The hint is: I=4

In the video we mixed Capital and regular letters, just to make it more “readable”, however, Capital and regular letters encode the same number, i.e. I=i=4.

This isn’t an easy one, so spend some time on it. You can ask for hints in the discussion, but don’t give away the answer. That you’ll be able to see on the next step. Good Luck!
