The second Su Doku book - even bigger, even better!
Su Doku is a phenomenon - and just about every national newspaper now carries the puzzles. You don't need to be a mathematical genius as the Su Doku puzzles are really logic puzzles that happen to use numbers- you solve the puzzles by reasoning, not calculation.
This new book includes: Standard Su Doku - the basic 9x9 grid Super and Maxi Su Doku - fiendishly difficult 12x12 and 16x16 grids Jigsaw Su Doku - if you thought the Supers were hard! Irregular Su Doku - something a bit different - but just as tricky The book is arranged in increasing order of difficulty, with enough puzzles to keep even the most ardent Su Doku addict busy! First published 2005.
