ALERT!: Entering some wrong answers will end the quiz
Each cell contains a number 1, 2, 3, 4, 5, 6, 7, 8, or 9. Only numbers are in this quiz. Only one number in each box. Using logic and the clues, determine the number located in each box. But before you start, there is one rule: there cannot be two of the same number in a row or column.
