New Puzzle Each Day
It's just like standard sudoku, but with diagonals! Each row, column, nonet, and diagonal must include exactly one copy of each number 1 through 9.
This version has a special puzzle for each day, too!
If you're new to the genre, consider trying normal sudoku on our website first.
