Best Sudoku app out there! – Sudoku.com - Number Games Review

I’ve tried different sudoku apps, but this one is by far the best. It is, however, more challenging than others. I play this all the time in my free time, for it relaxes my mind after a day of work. To have a doubt that the game is five-star quality is ludicrous.
