You've had a go at some of the current range of Sudoku books and magazines and done the daily Sudoku grids in the newspapers. Easy, gentle, moderate and even hard grids have been solved without a single doodle on the page. Only difficult, fiendish, diabolical and evil grids give real pleasure, all the rest are completed more out of habit rather than as a challenge. This book is the answer to your prayers, 132 of the toughest Sudoku grids around, that will challenge even the keenest of players. All grids have a unique solution and are supplied in a large format, as marking-up (with either subscript numbers or dots) will be required to achieve success. The grids are tough (equivalent to any fiendish, diabolical or evil grids found elsewhere) but are not so ridiculously difficult as to put people off - they are tough but fair. Prepare for the mental challenge that is Sudoku-GUI Retribution .
