Help - level 469 3

Not yet - awaiting update

It took forever - and went from no stars to 3 stars - nothing in between. I know I used the 2 Star gems move more than once - then got a power ball (or whatever they are called) near the end and took out colors one by one, and cleared the board with the last 2 hyper cubes. I played at least 500 games before I got there!

Never mind - finally got it....but now what?

I can clear this easily, but not scoring enough to get any stars, let alone 3 - any helps (note: have 3 stars on every level except this and 177)
