Although there is acid on the level (which will automatically clear the Candy Ice Cubes for you, try to match candies adjacent to Candy Ice Cubes when you can. Not only will this clear the Candy Ice Cubes quicker, but it will also reveal the trapped Wrapped candies quicker which can help you pop the Bottles. After all, the quicker you pop the Bottles the quicker you’ll move up the Bear.
Even though there are only candies of four colors on the playing field it can still be difficult to make special candies at the start of the level because of the limited space you have. Just take your time and make sure you don’t miss out on opportunities to make special candies.
When the acid level nears the top of the playing field match candies as high on the playing field as possible. Doing this will shift the largest amount of candies, hopefully start a chain reaction and create new opportunities to make special candies.
On a side note, to get a two or three-star score you need a considerable amount of luck with chain reactions. As you can see in the video above even with two Color Bomb candies at the end of the level I wasn’t even close to a two-star score.
