I’m a cryptogramaholic, so I was thrilled to find these threads a few days ago. I never timed myself, though, because I had to work them out in my head since they were on my phone. That proved to be a different kind of challenge, especially for a geezer like me. Fortunately, these haven’t been too difficult. Here’s hoping that memorizing what letter is what and remembering them throughout the process is exercising certain gray matter that might otherwise be getting flabby.
Thanks for uploading them!
Shall I add you to our ping list?
