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.

The mathematical puzzle CalcuDoku is fast becoming very popular. Solving one takes a combination of Sudoku-style logic reasoning and basic math skills, making it a much more interesting and satisfying puzzle. However, it is still not easy to find challenging CalcuDoku puzzles. This book has only those: 101 puzzles, each of which will keep even experienced puzzlers busy for at least half an hour. Included are, for example, puzzles using zero, the modulo operator, many 10x10 puzzles, one 12x12 puzzle, and even one 15x15 puzzle! The puzzles are printed at a large size, leaving plenty of spacefor notes. The third edition has twenty of the popular new "twin" puzzles: pairs of puzzles with the same solution, but with a different layout, so you can use clues from each puzzle to solve both.

About BookWant to exercise your brainpower and have fun at the same time? Then this book is for you. This book introduces you to the amazing world of Calcudoku puzzles. It will help you understand the rules of this puzzle. This book is perfect for players of all skill levels and ages. You will find 200 exciting puzzles, both for beginners and for professionals. HOW TO PLAYThe objective is to fill the grid in with the digits 1 through 9 (where 9 is the number of rows or columns in the grid) such that: * Each row contains exactly one of each digit. * Each column contains exactly one of each digit. * Each bold-outlined group of cells (block) contains digits which achieve the specified result using the specified mathematical operation: addition (+), subtraction (-), multiplication (×), and division (÷). As Calcudoku belongs to the same class of puzzles as Sudoku the puzzle can demonstrate a wide spectrum of relative difficulty. The grade is determined by a combination of opportunities to solve at each stage and the difficulty of the strategy that grants each solution. Puzzles almost like Killer Sudoku, but unlike Killer Sudoku, digits may repeat within a block.
