Our favorite strategy for any colour bomb order making level is to use each colour bomb individually on the candy colour that will do the least damage. For example, if you have a striped red candy, use the colour bomb on a candy that isn’t red. You’re aiming to be able to leave opportunities to make more colour bombs on the board by removing one colour candy at a time, without detonating the other colour bombs.
Pick off the candy colours one by one and after every colour bomb you detonate, look and see if you have any more match-5 opportunities. If they are there, work on making them before setting off the next colour bomb from the marmalade coated arsenal at hand. Take it steady, and you’ll get there.
