How to play Jigsaw sandwich sudoku
Sandwich Sudoku contains extra numbers outside the grid. These extra clues indicate the sum of digits between 1 and 9 in the corresponding row or column.
-
Each region must contain the numbers 1 to 9, without repetitions.
Here are some tips for solving Jigsaw Sudoku puzzles:
-
Start by looking for clues in the existing numbers. For example, if a number appears only once in a row, then it must be the missing number in that row.
-
Look for patterns in the numbers. For example, if a number appears in two of the three rows in a region, then it must also appear in the third row.
-
Use elimination to rule out impossible numbers. For example, if a number appears in a row and a column, then it cannot also appear in the corresponding region.
-
Be patient and persistent. Jigsaw Sudoku puzzles can be challenging, but they are also very satisfying to solve.
I hope these tips help you solve Jigsaw Sudoku puzzles.
