30 striped candies is a tall order on any level and there are also two 20 move bombs sandwiched in 4 hit blocks, but a striped candy will take care of that. Focus right away on making striped candies and using them to help clear up more space. Try to get rid of the middle 3 rows first, but take whatever you can. Make a striped candy whenever possible, you only have 10 moves to spare here, so 3 matches won’t do much for you.
