X-Sums Sudoku Puzzles Index Page

X-Sums Sudoku Puzzles Index Page
X-Sums Sudoku puzzle is one of my favorite Sudoku type. In this post I am listing all the X-Sums Sudoku puzzles which I have created recently. X-Sums Sudoku appears in two different forms. One is with the Classic Sudoku template in which X-Sums are applied on the Classic Sudoku puzzle. Another one is Jigsaw X-Sums Sudoku in which X-Sums are applied on Irregular Sudoku template. I have created X-Sums Sudoku puzzles which both the templates and below are the links to these puzzles along with the instructions to solve these puzzle types.
To solve X-Sums Sudoku, first look at the minimum and maximum outside clues. For example, if 1 is given outside, one can immediately put 1 in the first cell. Similarly if 45 is given outside then one can immediately put digit 9 in the first cell. Similarly if 3 as outside hint then one can put 2 in the first cell and 1 in the next cell to make the sum as 3. Also if 44/43 is given one can immediately put 8/7 in the first cell and 1/2 in the opposite edge first cell.
Another thing to checkout in X-Sums Sudoku is that if the sum of opposite edge given numbers is 45 then sum of digits in the first cells of opposite ends will  be 9.

Rules of Jigsaw X-Sums Sudoku
Place a digit from 1 to 9 in each empty cell so that each digit appears exactly once in each row, column and outlined region. Each outlined region is marked by thick borders.Additionally the clues outside the grid indicate the sum of the first X numbers placed in the corresponding direction, where X is equal to the first number placed in that direction.
