Does every sudoku have a solution?

Question asked by: mrquestion

Asked on: 07 Jan 2010

Every valid sudoku puzzle that is created has one solution that you can reach through using logic.

However, there are many possible grids that could be created that do not have one unique solution - and in that case, the puzzle is said to be invalid, ie not a valid sudoku.
