To achieve a decent score on the Angry Birds Heikki Silverstone (note, this level was renamed after the fact to, “Britain”) level requires the use of a power-up, which we’re using on the first bird. Trigger the power-up then launch Terence at a high arch so he hits the sweet spot just above the TNT. If you hit right the TNT will explode and a lot of the level will be destroyed and the pigs on the far right side will pop. Now fling the bomb bird straight ahead to take out the remaining pigs. My guess is you can probably 2-bird this, but we had to use the yellow bird to finish off one last pig. The score in the video below is 124,940.
Note, to obtain the power-up you need a code, which is available by "Liking" Heikki's Facebook page. If you're not a Facebook user we recommend checking the comments on our main article, as there is a lot of useful info there. Back to the main Angry Birds Heikki walkthrough page.
