The puzzle is circular for a start, with 8 concentric rings. Each ring must contain the numbers 1-8 and each segment running into the centre of the circle and through to the opposite side of the circle must contain the numbers 1 – 8 and or course there can be no duplicate numbers.</p> <p><b>16 x 16 Sudoku (10 included: 3</b> <b>Easy, 3 Tricky, 2 Tough, and 2 Diabolical)<br /> </b>The grid is larger at 16 x 16 and solvers must fit the letters A-F into the grid alongside the numbers 0-9. 16 x 16 Sudoku are more difficult, take more time and are more infuriating than the normal puzzles – but just as addictive!</p>
