Place digits 1 to 6 in the grid so that no digit is repeated within a row/column. Some cells should be blackened in order to avoid a digit see its consecutive in a row/column. A digit can see others in a straight line until its view is blocked with a black cell. Blackened cells cannot touch each other from the sides. No cell can remain empty.
