Containing standard puzzles and killer puzzles, the new Daily Telegraph sudoku collection is the perfect way to take your mind away from everyday life. The book is compiled with both addicts and novices in mind: each sudoku is graded according to its level of difficulty, from 'gentle' through 'moderate' and 'tough' to 'diabolical'. All solvers will find Michael Mepham's introductory tutorial an invaluable guide, and solutions are included at the back of the book.
