The Daily Diagonal Sudoku: Puzzle Game for Girls
The Daily Diagonal Sudoku adds one rule to the classic puzzle. Every row, column and box must contain the digits 1 to 9, and so must the diagonals.
Use the diagonals
The extra rule gives you more ways to narrow down a square, so check the diagonals as often as the rows.
Every day
A new puzzle comes out daily, and an archive keeps the earlier ones.
