Quad NC Repeat Killer 1 This is a repeat of the Quad puzzle as a killer - remember it is non-consecutive. The turquoise cages have exactly one repeat. The plain ones are standard no repeat cages. ZD came up with the idea of compulsory repeat cages and I did about 100 puzzles on DJApe's forum. They made interesting killers with slight differences in technique.  This one is very hard and you may wish to do it on JSudoku (which allows repeat cages) - no code as it does not cover repeats. |

Ed Tried to do this again on Thursday night from your position (which is part way on my original one) - but I did not get too much further. In particular I did some stuff on N9 the first time which eluded me then. It might have been the drink - on the other hand I'm doing it on JSudoku and I might have accepted on of its elusive eliminations that Udosuk hated. I'll try it again this evening - anyway I have an easier Decidoku Repeat I'll post tomorrow. I'm not sure how many of the old Repeats I can find as I've had many computer problems and changes over the last few years. I'm pretty sure Udosuk has all of them if he ever re-surfaces.
