Season’s Greedings level 1-17 may be the most difficult level in the entire Angry Birds series to earn 3 stars. The best strategy is to fire the Red bird through the square and rectangular snow blocks supporting the top-left pigs. You must pop all four pigs in one shot, which should put you over 21,200 points. Fire the first Blue bird roughly horizontally, splitting to break the small ice block, the two presents, and the pig in the bottom-left. At this point, you should be over 35,000 points. Arc the next Blue bird, splitting through the middle two sections of rope supporting the bells. You should pop the leftmost pig, at least. Repeat the shot with the next Blue bird, aiming a little flatter, and split through the remaining two pigs. The score in the video is 64,200.
Note: Higher scores on this level are a result of the Santa Hat glitch. This glitch has since been fixed and thus is no longer possible. While we don’t have a video, the trigger was the Santa Hat atop the bottom-leftpig, but resulted in a less extreme explosion. To see which levels have the glitch, we have tagged them.
