Sudoku X marks the spot for brain-teasing fun! We’ve amped up the challenge of traditional Sudoku by adding one mind-bending twist! Follow all of the rules of a classic Sudoku game – no repeats within the same row, column or 3x3 grid – but be careful. Each axis of the “X” of black squares that criss-crosses the puzzle is another “no repeat zone!”

Take your best shot at solving Sudoku X, but be warned: It’s easy to get hooked on this clever spinoff of the world’s most popular number puzzle!
