Level 172 (CCR) is the second level in Custard Carnival and the 16th moves level in Candy Crush Saga: Candies Revenge. To pass this level, you must score at least 250,000 points in 20 moves. When there are no more moves left, Sugar Crush will activate all special candies and score you additional points.
This is another survival level, as infinite bombs can spawn. It can be hard to deal with in 8 moves.
250,000 points in 20 moves? Seems crazy. However, 4 colors makes it easy to create color bombs.
