Level 286

Any hints to get through level 286 would be greatly appreciated. Thx

At the beginning activate as few light switches as possible. Focus only on advancing upwad by clearing the way to the special bubbles which destroy a whole line (I forgot the name of that type of bubble.)

Doing this will result in a smaller number of different colors of bubble in the queue, and let you advance more quickly in the next section.

Thanks. Finally got it.
