Times Samurai Su Doku 12: 100 Extreme Puzzles for the Fearless Su Doku Warrior

By Times UK and The Times Mind Games

These are the most difficult Su Doku puzzles in The Times range.

This is Su Doku multiplied: every column, row and 3x3 box must contain the digits 1 to 9. Where the puzzles overlap, the rows and columns do not go beyond their usual 9x9 length but the interlocking boxes give you more clues - and more complexity.

With another 100 new Samurai puzzles to vex you for hours, lose yourself in the four levels of this book: 10 Easy 40 Mild 40 Difficult 10 Super Difficult.

Even the speediest of Su Doku solvers will be agonizing over these ultra-complex, extended brainteasers.
