Es una longitud toma de rompecabezas, el lado, el total de la misma diagonal

It is a puzzle making length, the side, the diagonal total the same.

As there is not the time limit, please play slowly.

Please come to time killing.

I prepared for 3*3 size, 5*5 size.

If there is the hint that a number is fixed to from a beginning in 5*5 size, there is free to solve all by oneself.

5*5 size is said to be approximately 300 million ways in total.
