A challenge for the brain, but not for the eyes - crossword lovers with less than perfect sight can enjoy their favourite pastime without the frustration of trying to read miniature clues and fill in tiny boxes. Each of these puzzles - 125 in each book - takes up two full pages, and has large type and generously sized grids with easy-to-see numbering. And, of course, the well-constructed crosswords cover a diverse range of topics and provide hours of fun.
