What do you mean by "All the draughts are situated in the cells of the same color." . In the statment this in not the case, furthermove if it is true then we can't take droughts.

"A cell with coordinates (x, y) is white if (x+y) modulo 2 = 1, otherwise it is black." So two possible options: 1) all the draughts are situated in black cells; 2) all the draughts are situated in white cells.
