Fill the grid with the digits 1 to 9. Each row, column and 3x3-box will have exactly one of each digit. In green cells can only be even digits. In white cells both odd and even digits are possible.

Fill the grid with the digits 1 to 9. Each row, column and 3x3-box will have exactly one of each digit. In yellow cells can only be odd digits. In white cells both odd and even digits are possible.

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. Yellow cells must contain odd digits, green cells must contain even digits.

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. The arrows show the location of the same number in the previous or next column or row. So for example, the arrow next to the 9 in the first column means that the 9 in the second column is in row 1 - 4.

Fill in the cube so that on all sides of the cube in every row, every column and every bold bordered area every digit from 1through 9 appears exactly once. Additionally, the digit on the common edge of two sides must be the same number.

Puzzle:

Fill the grid with the digits 1 to 9. Each row, column and 3x3-box will have exactly one of each digit. The red points in the near of crosses where four cells meet each other show that the cell with the red points is greater then the three other ones. The blue rings in the near of crosses where four cells meet each other show that the cell with the blue ring is smaller then the three other ones.

Enter numbers from 1 through 4 into the diagram, such that on all sides of the cube in every row, every column and every bold bordered area every digit appears exactly once. Additionally, the digit on the common edge of two sides must be the same number.
