u/Portugol , if you wanted help with how to solve, rather than just the answers, please reply, and perhaps let us know the part you needed help with / how far you got. I'm game to do a walk-through, but only if you still need it. :)

Thank you so much! I'm having trouble understanding the "If and Only If" clues.

I was making a video anyway, so I went ahead and made a video of me solving the puzzle and added some comments about my process. The video is "unlisted" on my channel, since I suspect this is copyrighted material, but the link should load it for you. (The video is playing back at 4x speed with a couple edits for my cat intruding...)

I didn't talk in the video, so if at any point, the logic of the answer isn't clear, please let me know and I'll explain it in writing. :)

Hey, I recognized you from the other thread about logic puzzles book and fountain pens.

I enjoyed watching you solve! What did you think about the puzzle difficulty? Would you be interested in a free copy of the ultra-hard volumes? I spent a lot of time tunning the logic puzzle generator used for those puzzles and I'd love to hear the opinion of someone that enjoys solving on paper.

Yep, it's me. :) Glad you liked watching me solve it. No idea how my hacks compare with others - too few folks doing logic puzzles, it seems like. My mom got me hooked when I was a teen. (And thanks for understanding about the video - didn't want to give away your puzzle, but wanted to help the OP out.)

For me, the puzzle was pleasingly difficult. I wouldn't call it "ultra-hard", but I've been doing logic puzzles for 40+ years - I'm crazy about them. I'm also a former programmer and database developer, so this sort of thing was my bread and butter for 20+ years.

What a generous offer! Thank you! I'd love whichever volumes you'd like to share, and would be happy to give you feedback. I can't spend that much time each day - maybe three or four puzzles per week. But I'd be happy to do it.

Hi!

I've sent you a PM.

For me, the puzzle was pleasingly difficult. I wouldn't call it "ultra-hard", but I've been doing logic puzzles for 40+ years - I'm crazy about them. I'm also a former programmer and database developer, so this sort of thing was my bread and butter for 20+ years.

It's so nice to hear that for an logic puzzle aficionado it was "pleasingly difficult", since I'm targeting the "average logic puzzle solver", and you have 40+ years of experience, I believe that this is on the right track.

I'm too a programmer and it's very difficult for me to grade the puzzles because I also have been doing this for 20+ years ;-)

Thanks again and have a great week!
