News update: I just checked my spam folder and found EXACTLY WHAT I NEEDED: an excuse to post something meaningful in my Spider Solitaire blog after it ran dry for more than a month. I should probably check this folder more often from now on.
The word “SPAM” can be obtained by deleting the appropriate letters in the title of this post, but the word “HAM” cannot (rearranging letters is not allowed). Therefore, I have classified the image below as spam.

For what it’s worth, TreeCardGames is the software company that started it all.
Has anyone come across similar spam messages that are related to the Royal Game? If yes, how did you deduce it was spam? Let me know in the comments 😊
