Squiggly Sudoku adds a new twist to the latest global puzzle craze, replacing the square boxes with squiggly shapes. The familiar Sudoku rules are still in play; fill each row, column and box with every letter once. Sudoku fans can apply their favorite solving methods as well as rich deductions, from the interplay of the shapes, not possible in traditional Sudoku.
The unusual shapes allow more variety in puzzles sizes. This first collection of squigglies includes 120 puzzles in a range of size and difficulty, from 5x5 to 9x9. The smaller puzzles give a quick puzzle snack when you don't have time to solve a full course meal. And with different shapes in each one, every puzzle is a fresh treat.
If your Sudoku experience is getting repetitive, you need to try some squigglies.
