This Margin Sudoku is a special entry in our Fun With Sudoku Series, marking the 26th puzzle in the collection. It was originally created for the Indian Team's practice for the 2009 World Sudoku Championship, a year when three Indians reached the semi-finals. The puzzle's rule is straightforward yet powerful: the numbers outside the grid indicate the position of a digit within the first or second cell from the edge.
The solve requires you to integrate these margin clues with classic Sudoku logic, as well as the additional constraints of the diagonals and the center 3x3 box. This puzzle is a great way to experience a semi-final level challenge. It's print-friendly, making it easy to enjoy anywhere. Are you ready to tackle this Margin Sudoku?
