CalcudokuA Calcudoku puzzle uses the numbers 1 through 4 for a 4-by-4 puzzle, 1 through 5 for a 5-by-5 puzzle, and so on. Like in sudoku, each row and column must contain each number exactly once (creating what mathematicians call a Latin square). But, unlike a sudoku puzzle, none of the numbers are provided. You need to use logic to place the numbers in each cell according to the clues given in each “cage.” |
SudokuThe name “sudoku” is an acronym, coined in the 1980s for a longer Japanese phrase that translates to “the digits must be single.” The first sudoku-type puzzles appeared more than 100 years ago in a French newspaper, but sudoku as we know it didn’t show up in American puzzle books until the late 1970s. The rules are simple: Fill in the numbers 1 through 9 within the grid so that each number appears exactly once in each row, column, and 3-by-3 subsquare. |
MasyuMasyu (pronounced “MA-shoo”) is a Japanese word meaning “evil influence.” The objective is to draw a loop (consisting of horizontal and vertical lines) that passes through each box that contains a circle. When the line passes through a black circle, it must turn 90 degrees while passing straight through both adjacent squares. The rules for white circles are the opposite. The line must pass straight through white circles but must turn 90 degrees through one or both adjacent squares. |

Puzzle mania!
Tricky Logic Puzzles for Adults is filled with 6 different types of puzzles. Sudoku, Masyu, Nonogram, Calcudoku, Logic grids and Cryptic puzzles. The author Steve Clontz explains each puzzle, what it’s name means and how to work the puzzle. He gives tips and tricks to help you out to start. The book starts with the puzzles being at an easy level and then progressively gets more difficult. I have to say I remember the Logic Grids from school. If you know someone who loves puzzles or someone who’s under the weather I think this would be a great gift. There are 130 different puzzles so there is sure to be something for everyone.I received this book to review from the publisher and I think there’s a great variety of puzzles within it. I’m under no pressure to leave a review I’ve done so on my own accord.
