Recently a leading newspaper has conducted a sudoku competition...which involved the qualification round
The verification process was simple. Each sudoku had a unique <b>6</b> digit solution. the 6 digit solution was to be sent over phone or internet.
How can we get such 6 digit keys or solutions????

I've seen instances where selected squares on the board are highlighted, and the "key" is simply the values for those squares in order; you could also request an entire row to generate a 9-digit key. Obviously, the longer the key is, the less chance there is of someone getting the corrct key by accident.
