Pretty much the same as the walkthrough.
1st bird through the pig in the top structure and sometimes to the pig in the crane (another type of bird!!!)
2nd bird through the bottom to the tnt and clearing the level

Even if you miss the crane pig, the tnt explosion might still get him. So, don’t quit, fire the second shot, and you might get lucky.

101980. Same as methods decribed, baloon and TNT threw debris up very violently, toppling the crane. Two birds left.

I used the same method as JTB described, it took forever.

@Myselfiandme has the best strategy for high scores, but it takes a lot of attempts before the crane topples.

The next best strategy, to get consistents scores in the 93-95k region, is as follows:

First bird: aim for the wooden triangle on the crane. This will topple the crane and it’s worth spending one bird on just for points (unless you go for @Myselfiandme‘s much more difficult two-bird approach).

Second bird: as in video.

Third bird: little tower in middle.

Thanks for your strategy, worked liked a charm. Only 96K at the moment, but I am sure it will get better.

@f91jsw, that’s the same route I took and made out pretty good, that crane’s worth a lot of points together with the clawed pig when it falls over to the right.

The key to a high score two birdie is when and where to expand OB to throw up debris to knock off the right crane.
It’s pretty repeatable once you get it. I’ve got several 101K+, 103K+ scores and my current high of 105650.
First shot: Aim YB straight through the piggy in the little top left/middle structure. He will cut through and go on to get the dangling right piggy and break the piece of vertical wood blocking the bouncer. Here’s a screenshot:

This helps to expose the crane for your second shot.

Second shot: Is key to getting debris to fly up to topple the crane off the edge. You want to send OB horizontal through the bottom left bigger pig in the “roof”. Let him roll to the edge of the next roof and as soon as he lands at or slightly under the overhang of the slanted wood piece that makes up the left side of the second “roof”, manually expand him so that he ignites tnt and throws debris up to the right to knock crane off the edge. Here’s a screenshot of the trajectory:

In this screen shot I finished with 103330 but it’s the same trajectory I used when I got 105650.

Once you get the hang of the shot it becomes pretty repeatable. GL

@AngryAdvisor, thank you million times. God Lord, I tried it houndred times today I finally got above 103k. However, my first shot wasn’t that effective and wooden piece that blocks bouncer stay at the place.
stay cool, now I’ll check other of your comments in BP walkthroughs.

@lesleyg, thanks a lot for this strat. Yes, I’m late with playing this ones, got stuck on the Winter Wonderham AND a series of Birdday. Rovio was extreme productive lately.

@bernersenn – You’re very welcome, I’m glad it helped you and thank you to @all above for the comments. I didn’t get notification so I’m just seeing them…I’m always happy to know I have helped ;-)

btw – You’re not late…we definately got a lot of new updates very close together. I am just getting back to BP’s to finish the second half. I too was in WW and finishing Birdday Party udate, with several updates left to finish! Rovio has definately given us addicts so game time ;-)

Thanks AA @lesleyg for posting this alternate strategy. You do have a great “eye” for a better technique. Took me a while (stuck at 100, 103, and 104K but finally was able to aim my shots better.
Found that I could obtain 100k in score many times but to get higher than that, Yellow Bird had to take out most of the structure around the far right pig. It seemed to take less debris to push the crane up and get it to fall.
The Orange Bird was the challenge if for no other reason than all the debris and white clouds between the two slanted roofs. Finally notice that when OB is between the two lower edges of the slanted roof, there was more consistency in getting the debris to go to the upper right to hit the crane. If OB went any lower, to the stone blocks/tnt, I could not get the crane to fall.

@lesleyg, a very big Thank You! Your tip about when to expand Orange Bird is spot on! I think I got a few more points when part of the crane fell to the right, and part fell left, doing more damage below.

Thanks AA. Your tip got me out of a rut. I finally started breaking the 100k barrier after reading. The key is not letting the OB drop to low before expanding.. Finally cracked the top 100. Thanks.

Thanks a lot for the strategy.

For the second shot I found out that inflating a little sooner is helping to get repeatable destruction of the crane.
Here is a screenshot:

The cursor is pointing at the position where you should try to manually inflate the ob.

Of course you can’t see a thing when the bird is reaching this point so it’s guesswork ;-)

Here is the destruction I got for my highest score:

And here is the highscore screenshot:

Hope it helps a little.

Used strategy by @lesleyg for 112k. This level is changed, the cranes topples more easily now. I also get a few more k when a big part of the crane toppled left instead of right, doing more damage below.

I am adding this level to my growing list:

Is anyone else finding that this level is one that ends very quickly? I’ve tried to get off an extra shot after killing the pigs to see if I could get more than 10K of destruction points, but the game ends before I can throw a third bird.

@PlayDBird, I have noticed that on many levels that with orange bird. You can get more points then 10K if you leav hanging pig alive and use yb to knock and crash crane.

Well this is not going to be much help. Just got the top score for this level but not really sure of the detail of how it happened. I shot yellow bird through the green Pig in the house and it cut through the cable holding up the Pig in the claw. I then sent OB through the towards the TNT with the aim of manually expanding in the gap above the yellow spanner. What happened next I did not see, as the screen moved back to the left as if to prepare for launch of third bird. All I saw was the counter then start to climb and keep climbing until the high score was shown. I could not see what the destruction looked like, but can only assume the crane had been tilted to the right and destroyed itself. I did get a screenshot of the high score though and will look to post that as proof If I can work out how.

Well done. What happens is the orange bird tips the crane backwards and scores lots of points.
