Friday puzzles #3

Ok, so delayed a little later than Sunday. I’ve been busy.

On the other hand, here’s a sudoku with the givens in the shape of a Yin-Yang. Only I’ve just noticed that’s only true modulo a reflection – and we all know the sorts of trouble that quotienting out by an involution can get us into. So tomorrow I’ll put up a properly shaped puzzle. :)

Enjoy this incredibly easy fodder for now though!

EDIT: Here is the new, improved, properly shaped and rather nicely themed version, if I do say so myself. However, the large number of givens really does mean that it is still very easy.
