Angry Birds Summer Pignic was the first game in the Seasons series that had not been released in line with a holiday. At the time of release, the Seasons game had a Halloween, Christmas, Valentines, St Patricks and an Easter game, but nothing to celebrate a season even though Christmas and Easter obviously to some point represented Winter and Spring respectively.
Released on all platforms on the 21st June 2011, which was summer solstice (the longest day), the game worked in the same way as the Christmas version (angry birds seasons greedings) with 30 different levels that could be played as each day passed rather than when you finished the last level. This meant that by rights if the game was downloaded after the 21st July 2011, then the levels could be played from 30 to 1 rather than the other way around. With this being said, the game did keep to its increasing level of difficulty system that had been used on all the previous games.
