Help with level 104

Answer from: Anon
You need to connect them to the black stones before you unlock but does anyone know how to get the first 3 + bubbles?

Answer from: Bubble Girl
For most of them it works to stick other bubbles to the grey blocks to hold them in place before unlocking the chain. I still can't figure out how to get those very first ones to not fall... Hopefully someone will figure it out.

I think the first plus bubbles are there as a distraction. Sometimes, the game is setup to give you false leads and you figure out later that another way is better. I could be wrong about these but the chain breaks what is around it and there is no possible anchor.

Chain 1 - explodes all. Decide between your first two colors which would be better after chain explodes.
Chain 2 - doesn't explode all. Setup for plus bubbles, open chain, get plus bubbles, clear row.
Chain 3 - explodes all.
Chain 4 - setup for plus bubbles, match color before if you can, pop plus bubbles, clear row.
Chain 5 - plus bubbles will stick to chain 6. don't need to setup before
Chain 6 - setup for plus bubbles. In addition, plus bubble usually matches nearby top bubble in the final bubble section and you can pop those together.

Having same issue - can not set up any + bubbles to stay except one set (the group of which they anchored already.) Hope to figure it out!
