Zoo Fruity Merge

Zoo Fruity Merge is a physics-based "Scale-Evolution" puzzle built on the "Suika" (Watermelon) mechanic. The technical core involves circular-collider logic, where animal-themed fruits roll and settle based on their relative mass and friction. It is a test of volumetric management and spatial prediction, requiring players to merge identical species into larger forms without causing the container to overflow.

A series of animal-fruits are provided at the top of a transparent container. Your goal is to drop them strategically so that identical types touch and "Merge" into a larger, more evolved animal. Interaction involves tapping the screen to drop the item; you must account for the "Bouncing" and "Rolling" physics. The game ends if a fruit stays above the container's "Fail-Line" for more than 3 seconds. The ultimate objective is to reach the largest animal species.

Winning the merge challenge requires "Weight-Distribution Stacking." Do not place large fruits on top of small ones; this creates "Air Pockets" that quickly fill the container. "Keep Large Animals in the Corners" and use smaller fruits to "Nudge" matching pairs together. A pro tip is to utilize "Kinetic Merging"—dropping a heavy fruit onto a cluster to force a merge through physical pressure, clearing space at the bottom of the container before it gets too crowded.
