Ok.. humour me now....
How long do you think it would take to fill a grid, all 81 #s with a completley blank grid.... I have tried this and succeded . I would like to know if there is any one out there who has tried it also and how long it took.... for me .. it took a long long time...

1m 27sec

The usual: row, column and box, plus each diagonal containing 1-9.

Of course, there would be a gazillion solutions, but there are a few trivial ones that would take only the amount of time it takes to write 81 digits. Here is an example:

123456789
456789123
789123456
234567891
567891234
891234567
345678912
678912345
912345678
