Fill in the grid so that every row, every column, and every 3x2 box contains the digits 1 through 6. In all cells the number can not be the sum of the gaps of this cell with its orthogonal adjazent neighbors.

Example:

Puzzle:

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. In golden cells the number is the sum of the gaps of this cell with its orthogonal adjazent neighbors. In white cells the number can not be the sum of the gaps of this cell with its orthogonal adjazent neighbors.

Puzzle:

Fill the grid with natural numbers. In each cell the number is the sum of the gaps of this cell with its orthogonal adjazent neighbors. The clues along the edges tell you how many skyscrapers you can see from that vantage point.

Example:

Puzzle:

Fill in the grid so that every row and every column contains the digits 1 through 9. (There are no boxes.) Numbers going along the connected cells lines must be in increasing or decreasing consecutive order from one end to the other. So for example 3 - 4 -5 or 6 - 5 - 4 is possible, but 3 - 5 - 4 or 2 - 4 - 9 are not possible.

Fill in the grid so that every row and every column contains the digits 1 through 9. 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, 6 in the cells.

Example:

Puzzle:

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:

Fill blue cells (water) in the grid . The numbers tell how much water cells are in this row or column. In a box (fish tank) the water falls down. In the same box within the same line either all cells must be water or none.

Example:

Puzzle:

Fill in the grid so that every row, every column, and every 3x3 box contains nine different digits of the digits 0 through 9. Numbers outside the grid represent the missing digit in the corresponding row or column.
