Ever since 1923, when the first crossword appeared in a newspaper, we Brits have been addicted to our daily brainteaser. Some of us are wordsmiths who tax our grey matter by tackling the cryptic crossword, others are number-crunchers who like nothing better than wrestling with a sudoku or kakuro puzzle. The Bumper Book of Puzzles is designed to cater to all these tastes, and features a selection of the most popular - and fiendish - brainteasers from the Guardian and Observer papers, including: Sudoku Killer; Sudoku Kakuro; Quick crosswords; and Cryptic crosswords. The Bumper Book of Puzzles contains everything you need to get your brain into gear.
