The game revolves around managing flocks of birds as they fly and collide with one another. Players take on the role of guiding these flocks to their maximum efficiency, balancing population growth with collisions.
As populations rise, the challenge intensifies as birds are more likely to collide, decreasing overall efficiency. Players work to mitigate these collisions by optimizing flock sizes and movement strategies. The game runs in the browser and requires no download or registration, allowing for easy access and play.
