Zoo Hill | HTML5 Merge Game

Merge habitats and grow an empty hill into a zoo.

The old zoo on the hill stood empty, and a young keeper has big plans for it. A relaxing idle merge builder. Place habitats on an isometric plot, merge two alike into a bigger one, and let the park earn coins while you plan the next step. Merge two alike to build bigger homes.

Tap BUILD to place a new habitat on a free tile of the plot. It costs nothing — the only limit is free space. Drag two matching habitats together to make the next one in the chain. Every habitat from level 5 up earns coins every 5 seconds — higher levels earn more.

A lobby with quests, a spin wheel and a timed chest provides additional progression around the main game.

The game runs entirely in the browser. Progress is saved locally, allowing players to continue where they left off. After the first visit, the game can continue working offline. There is no ad SDK, analytics or tracking included in the build.
