Question 114
In the first row of a board $5 \times 5$, 5 tiles are placed that have a white face and a black one, showing all the white face. Each tile can be moved from one box to any of the adjoining ones (horizontal or vertically) turning it around in each movement. In addition, several tiles can occupy the same box. Can it be achieved through a sequence of movements that the 5 cards are in the last row, in different boxes and that all of them show the black face?
