Description

Superb puzzles to keep your mind in good shape. 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.Tridoku. The puzzle consists of nine large triangles. Each of them contains nine small triangles. Figures from 1 to 9 should be placed in the cells of each large triangle. The field contains additional lines, the cells of which must also contain non-repeating numbers. Two adjoining triangular cells should not contain the same numbers (even if the cells touch each other with only one point).50 Kakuro sudoku puzzles 17 x 17. 50 Kakuro sudoku puzzles 18 x 18. 50 Kakuro sudoku puzzles 19 x 19. 50 Kakuro sudoku puzzles 20 x 20. 200 Tridoku very hard sudoku puzzles (Veteran levels).
