Killer Sudoku 1


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.




Another Little Piece


Book Description

The spine-tingling horror of Stephen King meets an eerie mystery worthy of Sara Shepard's Pretty Little Liars series in Kate Karyus Quinn's haunting debut. On a cool autumn night, Annaliese Rose Gordon stumbled out of the woods and into a high school party. She was screaming. Drenched in blood. Then she vanished. A year later, Annaliese is found wandering down a road hundreds of miles away. She doesn't know who she is. She doesn't know how she got there. She only knows one thing: She is not the real Annaliese Rose Gordon. Now Annaliese is haunted by strange visions and broken memories. Memories of a reckless, desperate wish . . . a bloody razor . . . and the faces of other girls who disappeared. Piece by piece, Annaliese's fractured memories come together to reveal a violent, endless cycle that she will never escape—unless she can unlock the twisted secrets of her past.

Sandwich Sudoku


Book Description

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!
