It’s a color interaction game. Sort of. You have several red, green and blue colored balls randomly placed on a square field. Each ball can be spread over 5 free cells, no more and no less. A cell is free if it is not colored with the ball’s color. It can have another color on it. Different colors in a cell can be 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. The game is over when there are no more available moves. Have an awesome time when you take on the challenge of Color Add!
