I was bad. I put an impossible Sudoku in the letterboxes of my neighbours in Chatswood. A bit of marketing, if you will, by their local electrician.
I've been getting into the puzzles in the North Shore Times lately and found that they really appeal to my electrician brain.
It reminds me of fault finding. Figuring out which wire needs to go where on a switchboard, or why something's not working the way it should.
The sudoku in the local paper have a certain symmetry to them which makes them achievable, so when I saw this one online, I was stumped and slightly annoyed.
None of my usual methods proved very fruitful. I know I could just plug the numbers into one of the Sudoku solver apps and be done with it, but where is the fun it that?
I got my friend to look at the answer and give me some clues to appeal to my desire for symmetry.
I'll give you the same clues she gave me, see if it helps you.
Look at that, if you need another clue, I'll just say the word seven.....
That should put you on a bit of a roll.
The first block I solved was bottom left.
And then honestly, it all fell into place from there....
I don't want to spoil it for you, so that's all I'm saying.... You've got this.
