Same as @bonneypattycake. Screenshot to follow.

3 birds as mumsie said. 3rd bird resulted in top of middle structure fell left and flipped to detonate tnt. 4 birds left.

Thanks for the tip. Added 3k+ to my score. Chirp!

Ty @fenikus! I was stuck at 199,990 and with ur strategy busted well through 200,000.

Yup. Ty mm&m for sharing.

I am shocked by my score. I think something must have gone wrong but I will post a screenshot.

Flinging for days. Last few tries didnt accelerate yb and added 1000 to score.

Definitely go for the gold! And launch fast.

Bounced red off stone triangle. Red fell to the right and stones fell to the left.

Days upon days upon days. No new strategy. PB underwater to bubble up ice berg then roll uo left structure.
A few days snowed in and I just played angry birds for hours in end. Luck was on my side.

Yup. Under the anchor for the first shot, as Liam says.
The ice ball did not collapse the left tower, but lucky bounce got em all.
