Clear only single icons from anywhere (Useful to clear icons if you find yourself running low on matching pairs for a perfect game with a score of at least 1 point.
The code is intended to clear empty areas and keep in mind that single icons are worth 0 points.
You may get stuck with a Game Over if you are misusing the code and in certain situations where there are no matching pairs and you may need to backspace until you have at least two separate matching pairs of icons.
You may have to select a set of two or more icons if you turn off or after starting a new game and if turning on again at later point in the game to be able to clear single icons again.
