Incorrect solution

The grey square 3 (on th left) should also be changed to 7. (I forgot to mention this earlier). The current solution violates the "consecutive" constraint for the gray cells.

Oh... I can see it now :o)

There shouldn't be 7 on the cell [8,2] because there is 6 on [9,3]. So the solution on the pages is wrong...
But thank you!

In the given solution, I think 7 and 3 should be interchanged for boxes 2, 7 and 8.

Be carful when there can be an additional rule! These cells can't be switched because of the box 7.
Cell [8,2]=7 can't be =3 because there is another one on the gray square!

I hope you can understand my explanation Smile

Thanks

Yes, it is good now Kodyn, thank you for your time. Every square with an even in it has another even across each diagonal. It's hard to explain in words but your picture does a good job.

Problem

Hello,

This looks like a nice set of puzzles. I'm very excited to play this weekend!

For puzzle #13, would you mind clarifying what is meant by "placed symmetrically according to the diagonals"? I will use the 2 that is given in the example; it seems to me like the 2 in R3C9 could be put in...

A. R1C7 (obviously silly, but it's symmetric)
B. R9C3
C. R1C7

If I had to guess, I think R1C7 is probably right. Please confirm.

Jason, is it clear now?
Please let me know, if this picture is the right way to explain it Smile

Hi Jason,

I also had difficulty in understanding certain rules.

For this grid, I understand the action of the 2 in R3C9 as: R1C7, R9C3 and R7C1 are all even numbers, but not necesserarily 2. Symmertical to an even number is an even number.

Hope it's correct.

Kodyn, could you publish solutions of booklet's grids, I would like to see if I understand some rules.
