Lines Color Balls - Matching c

Choose any ball on the board and an empty field, where you’d like to set it (next to another ball with the same color). Balls can move only within empty fields. After every move three new balls will appear on the board. After setting a line made of at least five balls with the same colour, the line disappear, leaving space for more moves. Points are awarded for setting lines:
5 balls = 10 points
6 balls = 14 points
7 balls = 18 points and so on.
The game ends when there’s no more empty field left.
