SudoCue - X-File
SudoCue offers a daily X-File with 2 Sudoku-X puzzles. This the file for Sunday, February 10, 2019.
To my surprise, I could not find any websites that offered a regular Sudoku-X puzzle, even though this is one of the most popular sudoku variants. This gaping hole needed to be filled quickly, using the best quality Sudoku-X puzzles available. I found them in my own database. Complete the puzzles in such a way that all rows, columns, 3x3 boxes and the 2 diagonals contain digits 1 through 9.
Each X-File contains an X-R-Size and an X-Treme puzzle for the more experienced players. You can choose to play the puzzles online, print this page or select the number string and paste it into a cool helper program.
Beginners level: X-R-Size
Advanced level: X-Treme
