Clusterduck is an engaging mobile game where players breed ducks that can undergo bizarre mutations. Set on a lawn, players watch as ducks explore and lay eggs in three nests, ultimately hatching unique ducklings. As generations progress, unusual traits like horns and horse-like tails emerge, making each duck distinct. With hundreds of possible mutations, players must manage space by sacrificing common ducks into a mysterious pit, hinting at an underlying secret. The game combines elements of strategy, exploration, and humor, inviting players to discover and collect all the peculiar variations their ducks can achieve.
