No, you are supposed to use logic deduction to come up with the answers.
It can seem impossible at times, but a sudoku should always be solvable using logic reasoning.
Though a puzzle SHOULD be solvable using this technique , it is not always possible in more advanced puzzles. The most difficult levels require you to assume that a box is filled with one number or another. You pick one of the numbers, and then, you must follow the puzzle until you either solve it, or come to a impossible situation. Using the logical reasoning of "reductio ad absurdum", you then conclude that the number you picked WASN'T the correct number and start over from that junction point.
