There are apparently 6 trillion possible solutions. To be uniquely solvable a puzzle must have at least 17 initial numbers. The degree of difficulty of a puzzle depends on the number of initial numbers given and their distribution. As a rule of thumb, 24 initial numbers constitute a very difficult puzzle, whereas 48 numbers constitute a simple puzzle.
A valid Sudoku has a unique solution which can be found using an array of solving techniques without the need to guess.
