The game is about color interaction. You have several colored (red, greeen and blue) balls randomly placed on a square field. Each ball can be spread on 5 free cells (no more and no less). A cell is free if it is not colored with ball’s color and does not contain another ball. Different colors in cell are added to each other. And when three colors meet together in one cell, they disappear and you earn points. After each move a new ball arises. Game overs when there are no more available moves.
