With guessing a arrived to a correct answer that wasn't valid U.U.

Almost logical. A bit of guessing at the end.

Well I thought it was a lot of guessing. Didn't enjoy it at all. Had no clue what it was until the end and even then it looks like some kind of alien to me with no connection to "Paul" whoever that might be.

Terrible to solve and dissatisfying output.

It's an alien.

Thank you.

50% on the last two dots but straight forward otherwise.

Hint: the 10 starts in c12 after that you only have to make one guess.
