A Beautiful Gift

[@Rangsk]

Thanks for solving my puzzle! I'm actually quite happy with the solve, because spending time looking at how cool the interaction between those two length 6 whisper-sum lines is totally worth the cost of not disambiguating them earlier. The deduction that the vertical renban can't be low was indeed intended, though the way you found and explained it was much cleaner than how I was seeing it :) I couldn't help but give some "hints" to my screen, though, like "huh, I wonder if we should use ALL the lines in the puzzle?" All in good fun of course :) I'm kind of glad that I didn't "force" the use of Aad's Theorem for this puzzle. This was another attempt to make a SET-based puzzle using region sum lines, and like the last puzzle it can make seeing some of the logic a bit cleaner, but as you demonstrated it's absolutely optional. You didn't once mentioned it as a possibility, so if it had been required I'm worried how long you would have gotten stuck!

As usual zeta , tristan and rangsk...honored and amazed at your setting and solving skills. Every puzzle is watching a genius at work.

Found this channel by mistake but it's fun to watch brilliant constructors solve others brilliant constructions.

Well glad you found it, happy to have you here!

The 1/4/6 discovery was indeed just a lovely "aha" moment. Nicely done chaps, nicely done.

Thank you, it was such a lovely lightbulb moment!

Great solve! The way the whispers and sums play off each other really adds a dimension.

[@zetamathdoespuzzles]

Yes it was a fun puzzle! I think I recall rangsk saying you were the one to test solve it!

[@jtersesk]

@@zetamathdoespuzzles Yep, I did test solve it. :)
