Level 327 key

[wembley378]

Has anyone been able to get the key on 327 for the goal beat level without popping ice bubbles?
I don't see how it is possible. In order to get the top row to fall you need to pop use the star on Aqua and yellow, one of which is always touching the ice bubbles. In the screen shot I popped one of the stars with the wrong colour but I couldn't have won it anyways. Annoying as I used gems on the blower blocker.

When you throw a color at a star, it just removes that color from the board, but doesn't cause adjacent ice bubbles to turn that color, or to pop. So I don't see why that should be a problem. I have not achieved this goal, but it seems to me that to do so it would be necessary to make sure that hits to each of the upper two stars remove bubbles from the top row.

So very right, thanks Lincstake. It hadn't worked before so I thought it was the stars but probably hit one somewhere without noticing.
