(This riddle will only make sense if you know what sudoku is)
'You are playing sudoku and you aren't doing so good, you have only one box filled up all the way. You search for 5 minutes then you stop, you think you found one! Yes, Yes, you might have found one! Then you realize you got it wrong, you sigh then continue looking. 2 more minutes pass, still nothing!! You cannot believe it, you used to be the champion at sudoku! You have 3 sixes on the page, 4 threes, 2 ones, 3 fives, 4 twos, 3 fours, 3 nines, and 2 eights.'
Were is the Seven?
The Seven is in the box that is completely filled up.
