Less waffle, more puzzles to actually do! The idea this week is you have a standard sudoku puzzle to do – and rather than using the toroidal identifications, instead you are using those of the Klein bottle. Rather than try and laboriously try and rigorously explain the rules with respect to quotient spaces, topology, covering spaces, orientability and lots of other maths – what I’ve done instead is labelled the grid and coloured everything in so the rules are all completely obvious.
Who[*] says the internet is shortening attention spans and generally making everyone more stupid anyway?

[*] Ah wait, that’d be me. Expect less mercy next week.
Is this even well defined? When you are in the G/C-row you have two 5's (in G2=C2 and in G1=C1 there is both times a 5) Nice puzzle anyways.
