Rules of Twin Corresponding Sudoku
The object of this sudoku variant is to fill in each twin puzzle with numbers 1 to 9 so that each row, each column, and each of the nine 3x3 boxes contain all the nine different numbers 1 to 9.
This variant consists of a pair of linked standard sudoku puzzles each with some starting digits. To get a complete solution for the twin puzzles, we have to solve each twin puzzle with the usual sudoku strategy but we can only get the complete solution of the twin puzzles by substituting the corresponding values of the digits from one twin sudoku into the other.
Tips for solving Twin Corresponding Sudoku:
Look for corresponding cells that are already filled in. This can give you some clues about the numbers that go in other cells.
Use the Sudoku rules to eliminate possibilities. For example, if you know that a row must contain the number 6, and you know that the corresponding cell in the other grid contains the number 2, then you can eliminate the numbers 6 and 2 from all of the other cells in that row.
Try solving one grid at a time. Once you have solved one grid, you can use the corresponding cells in the other grid to help you solve the other grid.
