One strategy for Danger Zone level 21 is to send the Red bird upward so that it just barely gets caught by gravity. Frankly, it doesn’t do much, but a better shot alludes me. Launch the Lazer bird southward, far from the planet but inside the gravitational field, then redirect into the TNT on the far side. The corresponding explosion and the already-unbalanced structure should result in a full clear. The score in the video below is 68,260.
If you have a different strategy feel free to leave a comment below; however, don't just post your score via the comments, as that's what the leaderboards are for.



For iPhone users – if you’re looking for that one bird shot, the easiest method is too follow Loox’s suggestion – however if you zoom all the way out (as opposed to TenJoker’s suggestion), try to have the last dot of aim guide go right over the top of the second to the left point of the bomb. I have found this will consistently give you the needed hop (about 90% of the time) to hit the TNT. Getting the one birder – that’s a different story (hundreds of attempts).
My shot was on iphone as well. I guess it’s all about finding the shot that works for you, you really need to be able to hit the TNT consistently because like smonard88 said, it’ll probably take many many tries even if you hit the TNT every single time :-)
Actually I just realized that my shot probably only works specifically on iphone 4 and 4S because of the unique screen dimensions. Odds are that the shot alignment needs to be completely different on a 3GS for example..
Well on PC the red bird shot to the TNT is possible but didnt make 1 birder.
Shoot the redbird over the first building to the small planet’s lower circle, hit the suspended wood square which sends it to the helmet pig to make it jiggle, the redbird comes back along the plank toward the first building. If you have patience and you hit it just right, you get everything with one bird. I got a score of 69,160 and 3 stars.
Thanks so much! I got at last my 3* on this one with your tip.
This was the last level I needed for *** on all levels. After two days of trying this strat, it worked! 74,590 and I won’t play this one again for a long time!
Great strat @Amy! Finally got a 1-birder at 72650. :)
Same method. Fire red bird south of small, upper planet so that it sling shots into wood cube balanced on stone block. This knocks wood block onto east tower, destabilizing it and the whole lot overbalanceds to push everything to the right. One bird, 69,190.
I shot red so he looped into the bottom of the inner gravitational field just over the first structure, he went clear through hitting the far structure and bouncing back then slid down the ramp taking out everything except the TNT
3 stars..not a great score though…good luck all..
The score i have now was achieved as i think everyone Else followed @E-Star video sending red around the southern hemisphere through weeds, bouncing off little hidden hill into TNT..one bird..:)
Anyone notice that after sending the bird south to try and get the TNT you get what looks like a happy face on the screen?
One birder…fired red bird north just catching upper gravity field..accelerated using gravity from small planet struck small stone plank between right structure and middle structure score around 74000
