Each of the four Christmas Trees contains some
number of ornaments in its respective cells. The remaining cells are
empty.
The object is to group all the empty cells on each tree into three
congruent parts – a different kind of part per each Christmas tree.
The parts can be symmetrical. Two adjusted cells will belong to one
part if they are of the same color. To change the color of a cell,
simply click it. Click it until you find the required color. On every
4th click the cell will return to its initial state. |
