Merge nests and hatch a whole valley of dinosaurs.

A hidden valley lies beyond the volcano, and today the first dino egg was found. A relaxing idle merge builder. Place nests 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 and watch the dinos grow.

Tap HATCH to place a new nest on a free tile of the plot. It costs nothing — the only limit is free space. Drag two matching nests together to make the next one in the chain. Every nest 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.
