This is useful when you creating sudoku from answer. Check Given's Consistency This checks whether the problem has only one answer. It may take a few seconds if the problem is very difficult or Givens is too few(Time out is 15 seconds). This must be done before play. If an error is found, Show Result command shows a set of resultant values. Don't think the set is only one because the problem with error (No Answer or Multiple Answers) has multiple sets of resultant values in many case. So if you fix the error of the set, another error may occur repeatedly.
