Level 7 have a column of Mystery Bubbles in the middle. The Mystery Bubbles are really fun, but can be fatal. To insure a good outcome on level 7, I avoid to aim for the question marks as long as it is possible to burst some other bubble clusters. That way I do not get stuck with an infection, black bubble or a Bomb from a Mystery Bubble. You’ll need to remove the 6-7 lowest rows including the Mystery Bubbles to see the ceiling. The smart way to remove the Mystery Bubbles here is to have BOTH sides free for shooting one row above the Mystery Bubble you are about remove. Then you can shoot the Mystery bubble ABOVE a bad-luck bubble and hope for a better outcome.
When the ceiling is shown you’ll see the outcome of the Magic Potion 3 holes in the ceiling that you so wisely chose to use. ;-) Then you match the amount of spiders against clearing the 9 holes in the ceiling and choose to burst your way to the ceiling with fewer openings in the ceiling and/or less yellow/green spiders for the bubbles to drop on.
Please watch this video for Level 7 at Eternal Isles 6 played by Luca to get a better hold on it. =)
