Hexagon Cells is a logic puzzle. Goal is to score points. To get points you have to combine 6 balls of the same color together.
Combining more than 6 balls together provides a higher score, so combine them like e.g. 4 and 4 balls.
More and more random balls will fill up the board. Be aware when preparing your higher scores that a random ball connecting your prepared balls will steal your points and youll only get 1 Point.
