1)	Hi - I think there's a problem with the bottom left grid? I keep getting 2 6's in the 3rd row from the bottom not matter how many times I've tried it?!! Comment by: Vickie. Made on the 01st Mar 2006.

2)	Remember that a sum box may contain several time the same number ! And you will solve it ! Comment by: Phil. Made on the 03rd Mar 2006.

3)	I agree with Vickie's frustration. I know you say you can use the same number twice in a sum box but to me 23 should be 6,8,9 not 9,9,5. It adds another dimension but does not seem "pure" to me. Comment by: Susan Oates. Made on the 02nd Apr 2006.

4)	I kept making a mistake somewhere in the bottom left 9x 9 square and it took me hours to realize out that '23' can be made from 9+9+5 since it overlaps into another 3x3 square. If that '23' had 6,8,9 in it, the puzzle wouldn't work at all. Comment by: Sarah. Made on the 19th Nov 2006.
