What Is Merge Zoo?

Launched Feb 27, 2023
Updated Jan 2026

Merge Zoo is a casual mobile simulation game that combines merge-puzzle mechanics with zoo management and creature collection. Developed by Game Circus Studios, the app targets casual gamers who enjoy low-pressure, idle progression and "collect-them-all" gameplay loops. The game distinguishes itself through a high-quality, cute aesthetic and a non-intrusive monetization model that balances ad-supported content with optional in-app purchases. Positioned firmly within the competitive "merge-and-collect" sub-genre, Merge Zoo competes against industry heavyweights by offering a relaxing, family-friendly fantasy environment. Its primary differentiator is the seamless integration of candy-merging mechanics to feed and evolve a diverse roster of animals.
