100 Streams of Zetatude (renban, region sum, doublers)
(Published on 18. October 2022, 18:23 by Chilly)
The Rules:
- Normal Sudoku rules apply.
- There are 9 special cells, one in each row, column and box. All such cells contain different digits. These cells are either doublers or negators (at least four of each) and it is for the solver to determine which. A doubler cell has a value double that of the digit it contains. A negator cell has a value which is the negative of the digit it contains.
- The sums of the cell values in each region visited by a blue region sum line must be the same. Each visit to a region starts a new total.
- The cells on a purple renban line must contain consecutive values, in any order.
- Values separated by a white dot are consecutive.

Somewhat of a rollercoaster, this one! With the combo of having both doublers and negators with ambiguity, plus the fact it wasn't rated yet (and still not apparently =( , it was quite intimidating, so at first I thought hey, this is much smoother than I expected, but then reconciling the top and bottom rows was really tough, and it remained tough for a while after that! An impressive feat of thematic setting for sure, I really enjoyed it, especially as my first puzzle with negators (which in my inexperience I kept treating as if they had a value of zero lol)

Hi - thanks so much for the solve - interesting that the top and bottom rows were tricky - it was different from that in Zeta's solve. I think this one differs depending on which way you approach it. And still no rating :)
SPOILER - here's Zeta's solve https://youtu.be/_FR3bRqnxPw?t=13684

Oh, thank you! For sure, they made shorter work of it than I, but ahh, it still did take them a minute, didn't it haha -- and by 'top rows/bottom rows', I was referring to the T mostly in box 2, and how it ended up being connected to the 4 cell blue line stretch in box 8 (I realize it wasn't super precise lol). Anyhow, thanks for the reply and the link!
