400 KAKURO 13 x 13 + 14 x 14 + 15 x 15 + 16 x 16 best puzzles + BONUS + surprise

Sit back and enjoy the numbers game. KaKuro is a logical numerical puzzle, the mathematical equivalent of a crossword puzzle. In the cells it is necessary to place the numbers from 1 to 9, there are inactive cells (marked in black). In cells with given numerical values, the upper right value indicates the sum of the digits in the row, and the value from the lower left position is equal to the sum of the digits of the column below the cell. For example, the number 6 can be represented as a sum of 2 and 4 or 1 and 5; the same numbers (3 and 3) are not allowed. - 400 unique puzzles + bonus in 250 classics very hard levels Sudoku 9 x 9 (bonus puzzles need to 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.
