| sum sudoku: Killer Sudoku 1 Collins UK Staff, 2006-01-24 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. |

| sum sudoku: Color Sudoku Philip Riley, Laura Taalman, 2007-06 Sudoku fans will welcome this bright new twist to the popular puzzles! Every one of these ingenious creations--from Bold X to Rainbow Up--makes colors and patterns part of the solving fun. And although each puzzle maintains the normal 9x9 grid and follows the basic rules of the game, every style adds an additional restriction to intensify the challenge. In Worms, for example, swirly, squirmy shapes fill the grids; the numbers increase as you work your way from head to tail. Even/Odd features squares in two colors, depending on whether the number to fill it is even or odd. And in Positional Board, no two of the red squares can be the same number. They're all lots of fun! |

| sum sudoku: Sandwich Sudoku Clarity Media, 2019-06-12 Welcome to this brand-new book, containing 100 sandwich sudoku puzzles. This fun sudoku variant is also known as between-1-and-6 and between-1-and-9 sudoku.The rules are simple: first, you must obey the standard sudoku rules. These say that the numbers 1-6 (or 1-9) must be placed once in each row, column, and bold-lined box in the grid. The new 'sandwich' rule works as follows: around the outside of the grid you are presented with a series of numbers: one at the end of each row and each column. These tell you the sum of the numbers that appear between the 1 and 6 (or 1 and 9) in that row/column. This book contains 50 6x6 sandwich sudoku puzzles, and 50 9x9 puzzles. The smallest number that can appear around the outside of the grid is 0, and for a 9x9 puzzle this means that the 0 and the 9 are adjacent in the relevant row/column. The highest number in a 9x9 puzzle is 35 (2+3+4+5+6+7+8), which tells you that the 1 and the 9 must be at the start and end of that region. We hope you enjoy these puzzles. Solutions are at the back should you get stuck or want to check your answers are correct. You will never need to guess to solve these puzzles, but rather apply a combination of standard sudoku solving logic mixed with new logic introduced by the sandwich values around the edge of the grid. Enjoy tucking in! |

| sum sudoku: Taking Sudoku Seriously Jason Rosenhouse, Laura Taalman, 2012-01-19 Packed with more than a hundred color illustrations and a wide variety of puzzles and brainteasers, Taking Sudoku Seriously uses this popular craze as the starting point for a fun-filled introduction to higher mathematics. How many Sudoku solution squares are there? What shapes other than three-by-three blocks can serve as acceptable Sudoku regions? What is the fewest number of starting clues a sound Sudoku puzzle can have? Does solving Sudoku require mathematics? Jason Rosenhouse and Laura Taalman show that answering these questions opens the door to a wealth of interesting mathematics. Indeed, they show that Sudoku puzzles and their variants are a gateway into mathematical thinking generally. Among many topics, the authors look at the notion of a Latin square--an object of long-standing interest to mathematicians--of which Sudoku squares are a special case; discuss how one finds interesting Sudoku puzzles; explore the connections between Sudoku, graph theory, and polynomials; and consider Sudoku extremes, including puzzles with the maximal number of vacant regions, with the minimal number of starting clues, and numerous others. The book concludes with a gallery of novel Sudoku variations--just pure solving fun! Most of the puzzles are original to this volume, and all solutions to the puzzles appear in the back of the book or in the text itself. A math book and a puzzle book, Taking Sudoku Seriously will change the way readers look at Sudoku and mathematics, serving both as an introduction to mathematics for puzzle fans and as an exploration of the intricacies of Sudoku for mathematics buffs. |
