Note: 50 moves seems a bit too much to beat the level. Don’t be surprised if this number is reduced with an update. The strategy below would still apply though.
The first thing you should do is clear the blockers in the top right and bottom left corners. With each blocker you clear it will become increasingly easier to match candies and make special candies.
While you’re clearing blockers and when you’re done clearing blockers, try to make special candies you can use to hit the kernels and then the Chocolate that takes the place of the kernels.
With candies of five colors on the playing field you shouldn’t have too many problems making special candies. Still, take your time and don’t miss out on opportunities to make special candies. Consider holding on to special candies until you can combine them because of the combination’s enhanced effect.
Match candies near the bottom of the playing field (or as low as possible) as often as you can. Doing this will shift the largest amount of candies. This in turn will hopefully start a chain reaction that will create new opportunities to make special candies.
