While this may look relatively straight forward, it is a lot trickier than you think. First goal is to smash the white blocks at the bottom of the right column to allow pieces to flow over. Then, start matching the mystery eggs and creating combos to clear up. Your best chance to finish this level on time is to mix a color bomb and a striped candy or 2 color bombs. The striped candy/color bomb mix tends to be more effective though and easier to create.
