A match-three puzzle game where you drag birds around the screen to line up with others of the same colour, causing them to pop, thus scoring you points. Matching four or five birds will cause a super powerful bird to appear in the grid. Combos can be generated for even more points.
From the developer:
December 2010, we finished a project called, “Bird’s Island”. After months of rearranging and fixing the game, we were finally able to put an end to the project in April 2011 with a new name, "Birzzle". As soon as it was released, Birzzle became popular especially in Asia, and reached 7 million downloads worldwide.
