Jigsaw Sudoku Puzzles
Jigsaw Sudoku puzzles also called Irregular or Geometric Sudoku is a variation of the popular Sudoku puzzle. In a Jigsaw Sudoku, the grid is divided into smaller irregular patterns, separated by a thicker line from other irregular patterns. Each irregular grid must be filled in with a unique number.
Solving a Jigsaw Sudoku is a bit trickier than regular Sudoku. Instead of 3x3 small rectangles, you have to correctly fill these irregular grid patterns. So if you are solving a 9x9 grid, you have to get a unique number from 1 to 9 in each of these irregular grids.
That's why, if you are looking for a challenge, or if you just want to give your brain a workout, jigsaw Sudoku puzzles are a great option.
