Wie wunderschön! Geradezu magisch, wie es sich fügt!
Komplimentissimo!

Beautiful!

It's not impossible, if the unique solution has just the same symmetry as the hints, so you can't get another solution by using the symmetry. But this kind of puzzles with perfect symmetry tend to be very boring with a lot of T&E. (There was something like a hexagonal sudoku with perfect symmetrie in the portal if I remember correctly.)

@Richard: Your puzzle is fine. I just wanted to state, that it es inpossible to construct such a puzzle with an unique solution _and_ absolutly symmetrical hints (symmetrical positions and equal values). So you _must_ break the symmetrie. Statistica gave you a compliment, because you broke the symmetrie in the smallest possible way.

I don't understand the comments about symmetry. Symmetry is possible in a lot of different ways: horizontally, vertically, diagonally, full, rotational. If possible, I use symmetry whenever possible in my puzzles. It is one of my 'signatures'. I also try to use the different forms of symmetry after each other. This one has rotational symmetry: Rotate the grid once, twice or three times and the series of givens stays in place.

Es gibt keine eindeutigen Rätsel dieser Art mit vollkommen symmetrischen Vorgaben. Von daher ist Asymmetrie keine Frage der Ästhetik, sondern eine Notwendigkeit.

A beatiful example, how a mathematical structure can be the base for a really good puzzle.

The givens in this puzzle are placed in a rotational symmetrie.

2 <--> 3 denke ich.

Welche Asymmetrie?

Klein aber fein! Durch die nur leichte Asymmetrie der Vorgaben sehr ästhetisch gelungenes Rätsel!
