Jumelage [RSL Renban Twin Sudokus]
(Published on 22. October 2024, 13:09 by Christounet)
After I made this puzzle as part of the Zodiac Project, I figured I would try to make another pair of twin sudoku grids, this time with interactions involving ambiguous lines. This should be mostly approachable but there are some steps that are trickier towards the end of the puzzle. No bifurcation is needed though. Feel free to reach out if you get stuck. Also, take a look at the example or try to solve it first. It has some original deductions that I did not use in the main puzzle. Have fun !
Rules :
- Normal sudoku rules apply in both grids.
- Ambiguous lines : grey lines are either region sum lines or renban lines. Each line is of one type in one grid and the other type in the other grid. It is up to the solver to determine the nature of each line in each grid. Note : it may happen that a line has both the RSL and the renban properties.
- Renban lines : a renban line must contain a set of consecutive digits in any order.
- Region sum lines : digits on a region sum line have an equal sum N within each box it passes through.
- Even/odd : the digits in the grey diamonds have the same parity.
- Note : as both grids are identical, no anwser check is provided, because the solved grids could be switched.
Baby twins (example puzzle) :
Solution code: Row 7 of the grid with the highest digit in R7C1, then column 8 of the other grid.

I had to desactivate this puzzle for a few hours because there was a concern that it was non unique. I checked and it is unique, so it is safe to solve.

Another outstanding TwinDoku. It is so nice how they fit together, and the logic is so well integrated between them
