Just bought the level pack 1 the other day...have made up through 3-14, but the 3-15 game is driving me nutz!....

This is the one that starts with a blackbird and then has two more whitebirds and you have to knock down a stacked structure that forms a sort of pyramid like shape with a dice on top and a dice at each end left and right. The four green piggies you need to destroy are located under the structure...

Anyway, I checked out YouTube video of tips for this level pack for iPhone version. It was very interesting that Rovio changed the structure design for this specific level on the N900 version. There's a stacked column of round stone balls near the left end on the iPhone version, but they're not there on the N900 version...as a result I think this makes playing this level more difficult, at least for me!

Have tried 2 different strategies, neither one has been successful yet....

A) Aim blackbird towards lower part of structure on left end.

This does good job of often knocking out the 2 green piggies under the structure towards the left end. However, usually, this piles up the structure on top of the right side of the basement structure. As a result I can't seem to destroy the piled elements enough to get down to the basement level to destroy the other 2 piggies. At most I've been able to destroy one, but not two...so, fail...

Other strategy:

B) Aim blackbird up way high to land (hopefully) on peak of pyramid, to try and evenly blow away structure and expose the basement level to hit with eggs from the next 2 white birds...problem is clearing off enough of structure to allow eggs dropped to blow away basement structure to destroy the green piggies....

Anyway, hope this makes sense to some of you expert Angry Birders out there and can provide some tips...so, I can avoid going completely crazy and go on to next levels...

If others want to add tips for other level pack 1 games, feel free to do so...

Thanks!
