RF casual game

I find a fun rf casual game:
Goal:
Through swapping adjacent icons, connect three or more than three icons of the same type in a vertical or horizontal line. The more icons connect in a line, the higher score you will receive.
How to play:
Left click two adjacent icons, if three or more than three icons of the same type connect in a line, the two icons will swap their positions. The icons connected in a line will disappear and the icons above will fall down to fill the vacancy. You score when you clear icons on the game board. Only three (at least) icons of the same type connected in a beeline can be cleared. But if you can clear four or five icons at one time, you will get extra scores. If after the icons have been cleared, the falling-down icons form another beeline, you will get extra scores as well.
