Is the solution supposed to be unique? I get two possibilities. On the line summing to 31, the 2nd and 7th entry can take two possible values each

Hey Paul, thanks for taking the time to comment.

As far as I can tell, the 2nd cell in the line summing to 31 only has 1 possibility and there should be only 1 solution. However, I have made mistakes in my logic in the past.

Could you please email me or DM me on Twitter with the two possible combinations that you've reached? I'd love to double check and make sure there is a unique solution.

Had lost my first solution, so tried it again. This time with no problem. Must have been tired the other night!

No problem - sometimes I make these puzzles when I'm super tired and they have a couple mistakes.
