this is asking a lot of a beginner to be honest, i dont think the fact that its a 4x4 magically makes it okay
SPF> I am honoured to receive a comment from you, Shye. If by beginner I had meant 'absolute beginner', I would agree with you. However I mean 'beginner in the world of alternative sudoku constraints', and I do assume classic sudoku knowledge. With this nuance I hope you may agree that it is an adequate title for this puzzle series.
