In this game you must try to align three balls with different colors (blue, red and yellow) on their respective color (blue ball on blue square etc.) on the board horizontally or vertically.
This alignment can be achieved with one or more white balls (chameleons) who take the color of the square where they are.

In his turn, player pushes a ball from the lines outside of the board to the 3x3 grid board and sometimes this may push one ball out of the board to the outside lines.
