You can go to Mystery Sudoku Techniques to find a step by step solution and explaination of a mystery sudoku.
The Mystery Sudoku is my latest creation. Just like a sum frame sudoku, there are SUM NUMBERS in the border.
One of the 9 digits (eg 2) is the mystery digit. What do we know about this digit?
TIP: if the explanation is not entirely clear, than study the solution of the 1st puzzle thoroughly.
