#1 Bad array generation

[Anonymous]

I've checked a bad array generation:
After selecting "new game", the random generated grid is incorrect: Some times, there're the same number on the same line/column, and some times there is impossible to fill some squares (so, the complete grid is incorrect too!)

Reading the source code, I've seen that it generates nine arrays (one for each small grid). May be could be more usefull to generate each row and check each column, or even all, the complete grid.
