The Australian Puzzler sudoku Issue 117. no. 55. My answer and puzzle sudoku solver agree but are different to official answer. Has anyone else come across this. a science expert said that the chances of a sudoku puzzle having the 2 solutions is the equivalent of the numbers wrapping around the moon or something like that.

Helen,

Welcome to the forum. To many (myself included) a Sudoku with more than one solution is an invalid puzzle. Invalid puzzles are a lot more common than valid ones.

I don't know about wrapping the moon. Very Happy
