If you don't recall where it came from then it might have multiple solutions...

It is possible to have Sudoku puzzles with mutiple solutions...

What is impossible is that Sudoku puzzles generated by the Sudoku-program (available at http://www.WayneGouldPuzzles.com/) generates a puzzle with multiple solutions... (but there are other programs and persons generating there own puzzles, which might generate puzzles with multiple solutions...)

jayal,

According to my calculations, your puzzle has 68 distinct solutions! (I won't bore you with a complete list). Its lack of symmetry suggests that the puzzle is a work-in-progress and that the composer should have added a few more clues before he published.
