You need to create space in order to create color bombs. Each blocker is a 4 hitter, so try to get rid of the stuff in the middle and work out. All 6 candies are in play here, so it becomes a bit harder to create a color bomb. Try to do your best to keep 1 or 2 colors around as much as possible to increase the chance of making one.
