Fill in the grid so that every row, every column, every 3x3 box and the cyan cells contain the digits 1 through 9.

Fill in the grid so that every row, every column, and every 3x3 box contains besides the men digits 1 through 8. The men must see all 8 digits once if he looks orthogonally. His sight is blocked by walls.

Fill in the grid so that every row, every column, and every marked region, and cells with the same color contain the digits 1 through 9.

Fill in the grid so that every row, every column, the 3x3 boxes, both diagonals and the colored cells contain the digits 1 through 9.

Fill in the grid so that every row, every column and the cyan cells contain the digits 1 through 9. (There aren't any 3x3 boxes.)

Fill in the grid so that every row, every column, the cyan cells and both diagonals contain the digits 1 through 9. (There aren't any 3x3 boxes.)

Fill in the grid so that every row, every column, the 3x3 boxes and the colored cells contain the digits 1 through 9.
There is only one solution. You can find it by logic.
