Another sudoku variant this week, this time “extra region”. This does what it says on the tin really, same sudoku rules with the added constraint of having 1-9 in the shaded regions as well. This hasn’t really come out as perfectly as I’d have liked in terms of the logic needed to solve this, but I suppose the consolation is that it’s not too difficult. Enjoy!
