Figures from 1 to 9 must be placed correctly in all five squares. The puzzle contains regions of arbitrary shape; such sudoku may be called geometric or curly ("Jigsaw Sudoku," "Geometry Sudoku," "Irregular Sudoku," "Kikagaku Nanpure").Su-Kro-Kuro puzzles. ("Sukrokuro" - the name of the puzzle is made up of parts of the words "Sudoku," "Kropki," and "Kakuro") combines elements of three puzzles: Sudoku, Sudoku-points, and Kakuro. The task is a square grid with white and black cells. It is necessary to fill white cells with numbers so that in each row and in each column each number from 1 to N would meet only once. In black cells, the upper right value is the sum of the numbers in the row, and the value from the bottom left is the sum of the column numbers below the cell. If the numbers in neighboring cells differ by one, then there is a point on the border between them. If there is no point between two adjacent cells, the numbers in these cells differ by more than one. 200 Samurai Jigsaw Sudoku puzzles hard levels.100 Su-Kro-Kuro sudoku 11 x 11 puzzles levels.100 Su-Kro-Kuro sudoku 12 x 12 puzzles levels.- unique puzzles+ 250 sudokus difficult level that can be downloaded and printed.+ 250 maze puzzles that can be downloaded and printed.- only 1 verified solution.- all answers are at the end of the book.- exclusive puzzles.- a link to the surprise is at the end of the book.An excellent book for free time and mind exploration.I hope you enjoy the book.Best regards, Basford Holmes
