Book Description
Just when you thought it was safe to pick up a pencil Killer Su Doku is based on the original Su Doku grid, with the same rules and numbers—1 to 9—but with an added deadly twist. This time there is an element of arithmetic involved and there are few, if any, clues. The aim is to not only complete every row, column, and cube so that it contains the digits 1 to 9, but to also fill in the outlined cubes so they add up to the same number. Hints to solve the puzzle are hidden in the joined squares where only one combination of numbers applies. In the case of joined squares, if the printed number is 3, it should be 1 and 2 that go into the squares. Likewise, in the case of three joined squares, if the printed number is 6, the only combination possible is 1, 2, and 3. To add one final fiendish level, each puzzle also has a time worked out by its Japanese creators so you can try to beat the clock.

Book Description
The rules: insert the digits 1-6 just once in each a) row, b) column, c) bold outlined area AND d) in each white and gray rectangle. See Ritmeester's author page for his 18 other books. Peter Ritmeester is the inventor of the Hyper Sudoku, where four gray regions also contain 1-9. By applying this idea to a 6x6 sudoku, an entirely new dimension of logic is created, making a Sixy perhaps even more fun than a 9x9 sudoku. Not plain hard work, but plenty of logic and insight. Errors are unlikely, plus there are twice as many puzzles (and a six page How-To) in the same amount of space! In a Wacky Sixy few of the bold outlined areas are 2x3. This makes things much more difficult. Ritmeester, owner of PZZL.com, created the puzzles for all sudoku books presented by Will Shortz, with average reviews of 4.5 stars.

Book Description
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!
