Tips from Kelly Kneinston: Go straight up; Then alternated left and right shots as they became available. So, the short of it for me was ‘center, then L/R’
Pics, tips and strategies by Patti Frazier-Laundree:
Pic 1:Your first screen is filled with doom bubbles surrounding the outer portion of the field and do extend all the way to top near ceiling. Inside is a mixture of morph bubbles and regular bubbles. Outside the doom bubbles you will find only normal bubbles. What you can not see are the infection bubbles in the center spreading downward and outward as you shoot. Attack your bubbles from three directions as shown by the red lines in the photo. The outer sides have no barriers and with the right colored bubbles can be cleared easily. Just be careful of the doom bubbles. You also need to attack through the center as best you can to stop the infection bubbles.
You have a lot of bubbles to work with but if you feel you need more get the 7 extra bubble potion.
If you get into a difficult situation with the morph bubbles, use your rainbow bubbles.
Pic 2: Here you can see the infection bubbles attached to the ceiling after the lower portion of bubbles and doom bubbles have been dropped. Continue to clear the ceiling without hitting the remaining doom bubbles.
