Sudoku fans always keep an eagle eye out for fresh formats featuring their favorite puzzles. Here\u2019s one sure to draw them in: 210 sudoku that add a little spice to the mix by changing the standard 9 x 9 puzzles to 10 x 10. That means solvers get 100 squares instead of just 81! And the numbers go from zero to nine, rather than one to nine. Plus, the smaller sections within each grid are no longer 3 x 3: half the puzzles feature rectangular 5 x 2 boxes and the rest come in various random shapes, with heavy lines marking out the separate areas. It may seem daunting at first—but it\u2019s fun!
