Candy Crush Level 47 is not a difficult level at all. Being the 12th level within Chocolate Mountains, a bit difficulty lies in the locked candies. You have to make 15,000 points in a total of 40 moves at a minimum to pass this level successfully.
The key is to look for striped candy and combine the color bomb with it. You can combine the striped candy with wrapped candy and aim for a color bomb to get points. It is better targeting the central box in the beginning to get maximum special candies. It will overcome the nets around and result in perfect moves that will give you 15,000 points very quickly.
