20,000 Diagonal Sudoku Puzzles



Diagonal Sudoku puzzles are like regular Sudoku puzzles but with two extra groups. Not only do you have to put the digits from 1 to 9 in each cell of each row, column, and 3×3 square, but you also do that for the two diagonals. To differentiate these puzzles from the normal variety, dashed lines on the puzzle identify the diagonals.

As with other variations on the puzzle, the usual solving strategies work with Diagonal Sudoku too. But note that Diagonal puzzles normally start out with fewer initial values. These particular puzzles range in difficulty from easy to hard, but tend towards more difficult.

The puzzles are available in printable form as PDF files. Each file contains 100 puzzles, with 2 puzzles per page.
