Book excerpt: Sudoku For Dummies, Volume 2 will offer 240 original and addictive puzzles including new circular and 16 x 16 puzzles to add new dimensions to game play and keep the most avid Sudoku fan entertained. Of the 240 puzzles, 220 are the popular 9x9 puzzles, 10 are 16 x 16, and 10 are circular puzzles. Within each of these categories there are Easy, Tricky, Tough and Diabolical puzzle ratings; and each puzzle is clearly identified with the rating. More than just a listing of puzzles, Sudoku For Dummies, Volume 2 features a chapter explaining how to solve puzzles and the strategies involved. Additionally, readers receive all puzzle solutions in the back of the book. Finally, Sudoku For Dummies, Volume 2 includes a brief history of Sudoku (or Su Doku) for those interested. Descriptions of the newer types of puzzles are listed below. Circular Sudoku (10 included: 3 Easy, 3 Tricky, 2 Tough, and 2 Diabolical) The rules are similar to the normal 9x9 Sudoku but with some important differences. The puzzle is circular for a start, with 8 concentric rings. Each ring must contain the numbers 1-8 and each segment running into the centre of the circle and through to the opposite side of the circle must contain the numbers 1 - 8 and or course there can be no duplicate numbers. 16 x 16 Sudoku (10 included: 3 Easy, 3 Tricky, 2 Tough, and 2 Diabolical) The grid is larger at 16 x 16 and solvers must fit the letters A-F into the grid alongside the numbers 0-9. 16 x 16 Sudoku are more difficult, take more time and are more infuriating than the normal puzzles - but just as addictive!

Book excerpt: If you're looking for really challenging Calcudoku (also known as Kenken) puzzles, then look no further. From the reviews of the previous edition of this volume: " His easy puzzles equate to the NY Times hard -- his hard can be off the charts but all the more satisfying when solved. ", "I highly recommend this book for the avid solver." - JHackley. "These puzzles will keep you busy for hours. " - Rockman. "I have tried every difficult, advanced kenken and calcudoku book there is and this one is the most challenging." - Jorge Lobo. "No solutions are provided in the book. For me, this was a plus, since it eliminated my tendency to peek at the answers and instead forced me to work harder at finding the solutions." - Richard Klein This 4th edition has 20 new puzzles (with exponentiation, without operators, with exponentiation and zero, and with negative numbers), so it now also has 121 puzzles (just like volumes II and III of the series). It also features extended explanations of the variations on the standard puzzle, as well as step-by-step solving guides for two tricky sample puzzles. Note that there are no solutions in the back (except for the example puzzles). If you do need a hint, the solution to a specific puzzle, or even all solutions, you can send me e-mail (address is in the book) and I'll send them as a PDF.
