Fill in each row and column three number from 1 to 9. The difference between each pair of numbers in the row or column must be equal. Moreover the numbers are ordered in the rows from left to right and in the columns from the top to the bottom (i. e., 1 - 2 - 3 oder 2 - 5 - 8 oder 3 - 5 - 7).
Example:
Puzzle:
Fill the grid with the digits 1 to 6. The digits represent the height of the skyscraper in each cell. Each row and column has exactly one of each digit. The clues along the edges tell you how many skyscrapers you can see from that vantage point and/or what the first number is that you can see.
Fill in the grid so that every row and every column contains the digits 1 through 5. The marked boxes must contain consecutive numbers, i. e., if such a box has three cells there can be 3, 4, 5 or 3, 5, 4, but not 3, 4, 1 in the cells.
Example:
Puzzle:
Every bold outlined section must contain the consecutive integers from 1 to the quantity of cells in that section inclusive. Adjazent cells must be different, even if they are diagonally adjazent. In rows or columns the digits can be repeated,
Fill in the grid the digits 1 through 3. The digits in the boxes must be either all equal or all different. Horizontally or vertically adjazent cells of different boxes must be different.
Fill in the grid so that every row, every column contains the digits 1 through 6. On the same brick never should be two odd or two even numbers.
Fill in the white cells of the grid the digits 1 through 5 so that no row and no column contains any number twice. In each row and column the numbers are alternating larger and smaller.
Fill in the grid so that every row, every column, and every 2 x 2 box contains the digits 1 through 4.
Fill in the grid so that the grid contains the digits 1 through 9. Digits in the outside equal the sum of the three numbers of the corresponding row or column.
