Travel Size Calcudoku 9×9 Add

TRAVEL SIZE CALCUDOKU

Do you love Sudoku, but are looking for something just a little different? Calcudoku is similar to Sudoku, but with a twist! You still complete the same 9x9 grid with no numbers repeated in a row or column, but this time the numbers need to add to a target sum. For example, 2 squares in the grid may need to add to 9, so you can use 1 and 8, 2 and 7, 3 and 6, or 4 and 5.
