Combos
Create big chains to get busy bee pieces. When they are matched, they will remove an entire row. The longer your chain, the more busy bees will be created. Put two or more busy bees in the same match to cause an explosion that clears out pieces both vertically and horizontally. Busy bees should be used in the levels where your task is to clear out rows or columns of honey. Also use them to break out frozen baby bees.
