This Sunday at the Delhi Sudoku & Puzzle Meet up, we solved some sudokus from Japan's World Sudoku Championship selection contest. Out of all the sudokus we solved, I liked the Edge Difference Sudoku the most. This was the first time I was solving this variant. On my way back, I got an idea for an Edge Difference Sudoku I could create. And here it is! Do solve and let me know how you find the sudoku :)
Btw! Something lovely is coming up for the 100th Sudoku (along with chances to win prizes)! Stay tuned!
Rules: Place a digit from 1 to 9 in each empty cell so that each digit appears exactly once in each row, column and 3x3 outlined box. Digits placed outside the grid represent the difference between the first and the last digits in that row or column.
