Here it comes: a revolution in sudoku solving! This is by far the most complete guide to cracking these addictive puzzles ever produced, with tricks even the experts won’t know. While most books might have a few pages of introduction before proceeding straight to the sudokus, this one covers it all. Hidden pairs, naked pairs, X-wings, jellyfish, squirmbag, bivalue and bilocation graphs, turbot fish, grid coloring, chains: every single one is here, and much more too, including the exclusive Gordonian logic methods (Gordonian rectangles and Gordonian polygons) that will turn even the hardest puzzles into a breeze. Of course, there are hundreds of sudoku for practice. A very special addition: a reprint of the very first sudoku ever published in 1979, from Dell Pencil Puzzles and Word Games magazine!  

Everyone knows sudoku is enjoyable—but these addictive puzzles also come in endless variations too! They range from simple to very difficult, and can take almost no time to finish…or require many hours. This entertaining collection showcases a wide range of possibilities, offering solvers who have become accustomed to the standard rules and grids an exciting new challenge. Select from Mega Sudoku that provide a real workout; Diagonals or Odd and Even versions with extra constraints; Sum Sudoku that merge with kakuro; and Multisudoku with overlapping puzzles. There’s something for every level—12 x 12 puzzles, ones with irregularly shaped areas, even Mini Sudoku—and lots of fun for everyone.
