Book of Sudoku Variants - Suguru, Futoshiki, Binary, Numbricks, CalcuDoku - 200 Easy Puzzles Book 3

(Suguru) also known as Tectonics or Number Blocks, is a Japanese puzzle invented by Naoki Inaba. The task consists of a rectangular or square grid divided into regions. Each region must be filled with each of the digits from 1 to the number of cells in the region.Also, adjacent (touching) cells should not contain the same number, even diagonally.Futoshiki(from Japanese, literally "not equal"; also known as "Hutoshiki", "Unequal")Place numbers of the given range in the grid 9x9 such that every row and column contains each number exactly once. Inequality constraints must be satisfied. The open end of the sign denotes the greater number.(Binary) (also known as "Binairo Puzzle", "Takuzu", "Tohu wa Vohu") is played on a rectangular or square grid. The goal is to fill in the grid with digits "0" and "1" according to the following rules: Each box should contain a zero or a one.No more than two similar numbers next to or below each other are allowed.Each row and each column should contain an equal number of zeros and ones (or one more for odd sized grids).Each row is unique, and each column is unique.(Numbricks) is a type of logic puzzle.Numbricks puzzles are similar to Hidato. The most important difference is that it is only possible to move 1 node left, right, up, or down. It is played on a rectangular grid of squares. Some of the cells have numbers in them. The object is to fill in the missing numbers, in sequential order, going horizontally and vertically only. Diagonal paths are not allowed.(CalcuDoku)Each puzzle consists of a grid containing blocks surrounded by bold lines. The object is to fill all empty squares so that the numbers 1 to N (where N is the number of rows or columns in the grid) appear exactly once in each row and column and the numbers in each block produce the result shown in the top-left corner of the block according to the math operation appearing on the top of the grid. In CalcuDoku a number may be used more than once in the same block
