You must perform two colour bomb + wrapped candy and two colour bomb + striped candy combinations. Four colour bombs + special candies are not easy to do.
Although there are two colour bombs provided at the bottom of the board, it can be hard to bring the special candies down, and there is a high chance that the special candy will detonate the colour bomb before they can be combined.
In addition, the chocolate can eat the two provided colour bombs. If not controlled, it can eat most of your candies too.
With five colours, it is not hard to make colour bombs, but still not very easy, and with five colours, the cascades may detonate any special candy and this may lead to the detonation of your colour bomb. It can be a very hard candy order level like level 347.
Focus first on clearing the icing, then carefully clear the chocolate to avoid the colour bombs on the bottom being detonated.
If you can, make an early colour bomb + striped candy combination, so most of the icing and chocolate will be destroyed.
Try your best to make a striped or wrapped candy next to the colour bomb, and combine it.
It is better to combine it with a wrapped since it will remove two colours, making it easier to make a new colour bomb. Combining with a striped candy can also be helpful but be careful because there is a chance that striped candies will detonate the other colour bomb.
Take note that the new effect of wrapped + colour bomb does not remove two candy colours and instead makes wrapped candies, only making things worse.
Now this part requires some luck: just make colour bombs and combine them with special candies.
