Download or read book Killer Sudoku 1 written by Collins UK Staff and published by Harper Collins. This book was released on 2006-01-24 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: Strimko is a logic number puzzle invented by The Grabarchuk Family in 2008. It is based on the idea of Latin squares described by a Swiss mathematician and physicist Leonhard Euler (1707-1783) in the 18th century. All Strimko puzzles are solvable with a pure logic, no special knowledge is required. Strimko uses only three basic elements: rows, columns, and streams. All elements have equal numbers of cells, and the goal is to make each row, column, and stream containing the whole set of specified numbers. Cells in the grid are organized into several streams of equal length, which often run diagonally and even branching. Such mechanics creates entangled patterns resulting in interesting challenges and unusual logic. This book contains a specially designed collection of 150 easy-to-master puzzles with 4 x 4 through 7 x 7 grid sizes. Puzzles are arranged from the easiest to the hardest ones so that you'll progress in solving skills with each next puzzle. Strimko challenges were handcrafted by Helen, Tanya, Serhiy, and Peter Grabarchuk, and up to date hundreds of original Strimko puzzles were published in various forms and platforms.
