What is Merge Zoo?
Merge Zoo is a casual physics puzzle game created by Critters Studio and released in July 2025. The core gameplay revolves around launching animal spheres from the bottom of the screen to collide matching creatures and combine them into larger beasts, aiming toward the final elephant. The upward firing dynamic puts a distinct spin on classic watermelon style merging puzzles. You can play Merge Zoo directly in your web browser on desktop and mobile devices without downloading any files.
Key features
- Upward projectile physics: Launch animal balls from below and let momentum dictate their resting spots.
- Dynamic creature combining: Collide identical species to evolve them into larger wildlife.
- Elephant objective: Work through sequential animal tiers to assemble the largest possible creature.
- Boundary limit: Prevent the accumulating stack from crossing the upper line to avoid defeat.
- Responsive device support: Enjoy smooth touch and mouse mechanics across phones, tablets, and computers.

Merge mechanics and boundaries
Each shot introduces a new animal orb into the arena. When two identical animals touch, they instantly merge into a single larger creature. Because each combination produces a larger sphere, space management becomes increasingly tight as the board fills. Miscalculated shots can create awkward stacks that threaten the upper boundary. If any resting animal crosses above the top line, the run ends immediately.
Tips and strategy
Targeting matching pairs directly helps keep the board clean before clutter accumulates. Using the side walls for bank shots lets you squeeze balls into tight corners beneath larger animals. Setting up adjacent matching tiers prepares smooth chain reactions when a new animal lands. It is also wise to avoid piling tall stacks in the center, as unstable piles can easily topple over the top line.
