I found another:

1321
3111
2313
3233

I guess it’s a variation on the original solution.

Got Mike’s solution as well,and had Steven J’s question as well. Are you confusing Soduko square with Magic Squares?

I’ve been starting my chem class lectures with these to help get them thinking before I teach. They love them. Keep them coming.

@Erin – I tried that one too, but the diagonal from lower left to upper right doesn’t add up to 8.

The instructions state 9 squares inside the red grid need to have 1, 2 or 3. I can only assume the other 7 squares can contain any other numbers including imaginary numbers.

Mike does indeed seem to have found a second solution – nice job! I’ve edited the puzzle to add this to the mix.

And Lugh is correct about Lauren – the numbers given in the puzzle do have to remain in their original positions.

@Lauren, doesn’t your second row have to end in 1? I mean, that is one of the three provided numbers.

Other than that, it works. ;)

I got the same answer as Mike and Aaron.
