### multiple solutions

My daughter and I are new to sudoku puzzles and in doing our first one (in local newspaper), came up with 2 different solutions, but both meet all the rules for a solution. Is this normal? (3x3 puzzle).

I see from previous postings that there can be a large number of solutions to a particular puzzle and some "players" seem to enjoy examining how the puzzle works and how many solutions can be obtained for the same puzzle.

we generally require a puzzle to have exactly one answer

would you care to post the original puzzle from the newspaper?
thanks

A proper Sudoku puzzle is supposed to have only one solution. So either the puzzle is defective, or you made a mistake. (If it was a newspaper puzzle, I suspect the latter.)

By 3x3, I assume you meant 9x9 with 3x3 boxes.
