Vice Versa
(Published on 20. November 2022, 06:00 by ICHTUES)
Rules:
- Normal Sudoku rules apply.
- The positive diagonal must contain all of the digits 1-9.
- Black dot = 1:2 ratio, not all dots are necessarily given.
- Two purple lines (or dots) that map onto each other by 180° rotation form a single renban.
- (e.g. if r8c45 are from [79], then r2c56 must be from [68], being a four-cell renban)

Bemerkenswert, wie du aus einer neuen Variante in so kurzer Zeit ein so tolles Rätsel baust. 100% Symmetrie und ein sehr cooler Solvepath :-)

It might be better to color the rotation symmetrical lines, and specify that lines of the same color must form a renban. Like this:

Of course, the solver can also do this themselves in CtC using the pen tool. But visually it doesn't work as well.
