Thank you so much for featuring my puzzle! The 5s on the forward diagonal were indeed the intended break-in, and I used plenty of coloring myself while setting it.

And I do use they/them pronouns; thank you for not defaulting to he/him or she/her!

91:56. What a rewarding puzzle this was! It fell right on that line of "hard" and "impossible" for me. I had absolutely no idea where to start, then struggled my way into deductions and colouring. This is the first time I've ever muttered things like "that's a 1 6 red triple!" or "that can't be a 2, 3 or purple!" to myself.

Took me too long to spot the 3s in box 5 pointing at the thermo in C1, which fixed the central cell (highlighted green in Mark's solve) and quickly the rest of the puzzle. Of course Mark just breezed past it!

Watch this as soon as it is on just to be one of Marks favorites

I haven't done that many anti-diagonal sudokus, but this one is probably the most entertaining of them. Really clever use of the thermos to help with the colouring. And great solve, Mark!

[Thebrooky]

As a relatively new watcher, hearing "I don't know what pronouns Jordyn prefers, so they" made my heart really happy. Thank you, Mark, for proving the CTC community is a welcoming an accepting community. I'm trans, so it's always worrying every time I find a new channel whether or not the people behind the channel support who I am as a person. Hearts to you, Cracking the Cryptic.

14:52, ask yourself if 6 in the orange cell in box 1 is still possible. 🙂 This would make it a lot easier.

[VeritasUnae]

Such a wondrous rainbow formed from those diagonals! It was lovely to see how Mark broke into this one, and all the logical deductions that flowed from it. The left side thermo really seemed to put in the most work helping to disambiguate things.

You were a great moderator on Simon's Witness game! This was a fun puzzle!

[LorisLaboratory]

Thank you for sacrificing views on your video to accommodate Simon's stream! ;) You were an amazing mod there btw, thank you for keeping chat in line! <3

[artursruseckis]

after 14:34 all I could focus on was mentally screaming "ORANGE IS NOT 6"!!!

[Gonzalo_Garcia_]

19:31 for me. I loved this one!! Incredible logic here, what an awesome puzzle.

[mathemitmanger]

That Spanish Inquisition joke made my night...

[Swisswavey]

I found that one quite challenging, it took me 52 minutes, but I loved it. It made me think but I never felt totally stuck. Thank you for uploading.

[wanderlustwarrior]

31:47 solve time. A fun and colorful puzzle!

[TurquoizeGoldscraper]

24:17 for me - I certainly wasn't expecting the Spanish Inquisition.

[theashen]

Really enjoyed this one. Found the break in fairly quickly once i understood the order on the diagonals.

[johnholland]

Whenever I feel bad about writing in too many pencil marks I come and watch Mark so I can feel better about myself 😅

[Coyotek]

28:30 ... but I admit that I did resort to a bifurcation (to rule out 6 for r4c6) in my solve; even after that, it took me a bit.

Tough puzzle (for me, anyway).

[catnip]

Mark I just want to say you're doing a brilliant job moderating the chat!

When can we expect you to stream a puzzle game?

[garanceadrosehn]

I have to say that the CtC group on Discord provide a lot of useful input for this channel!
