Four Times Nine Equals Six Squared (Posted on 2006-10-16) Difficulty: 3 of 5
Each of the numbers 1 to 9 appears four times in the 6x6 grid. If a number appears twice in any row or column, it is mentioned in the relevant clue.

I believe the clues for four times nine equals six squared are incorrect.  The rules say only 4 numbers each.  You are asking for 5 nines. Column 1 and 5 each need a nine since you are canceling out 3 numbers each.  Column 6 is asking for 2 nines.

For column 3 to total three lowest numbers 14 , the six numbers need to be 3-5-6-7-8-9.  This would give you 5 nines.
