Unique puzzles. 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. 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. Number Cross Sudoku. The number cross is a square grid with numbers. The solution is to shade some cells. The first row and the top row of numbers show the sum of the numbers in white cells in the corresponding row or column. + 250 sudokus difficult level that can be downloaded and printed. + 250 maze puzzles that can be downloaded and printed.
