Legend has it that mysterious treasures are buried deep underground. Are they priceless? Are they magical weapons of extraordinary power? Archaeologists have been working hard on excavating the area to uncover the truth. In attempts to unearth buried treasure, many have built underground cities, revived dinosaurs from their extinction, and trained them to do their bidding. Cities are forming underground, one after another.

However, this new world is incomplete without you. Your subjects and dinosaurs are calling out for a wise master who will guide them through the creation of this underground kingdom.
-- Each floor of the undercity has its own special traits. You are the one who decides what goes where!
-- The dinosaurs have great powers. You can collect their eggs and hatch them!
-- Your subjects have their own unique characteristics. Their work ethic depends on your management!
-- You must collect more sophisticated equipment for your workers. The future of your undercity depends on them!
--You can excavate tunnels to connect your undercity to a friend’s.
-- Visit your friend’s undercity to see who has rarer treasures and more powerful dinosaurs!
-- Do you want to own powerful, hybrid dinosaurs? Go to a friend’s undercity and breed your dinosaurs to get one!
-- Available on iPhone5. If you don't have constant access to wifi, don't worry! Most of the game features are accessible without it!

We’ve been waiting for you for a long time, Your Grace!

eh who cares?


Um...How am I to make friends when NO ONE accepts? I've tried at least 15 people and not one person has accepted. Even some of the people who have put their ID up on here I have tried and nothing. Is anyone else having this problem??? I won't put up my ID if this is an actual bug.


I'm not able to buy coins

How can I continue to play this game when I'm not able to buy any coins? I started to really like this game and now I have to delete it from my apps 😢😥😤


Gets boring fast

two stars for an interesting concept. Combines resource management with find-it-now and a little bit of RPG. Wish there was more strategy and risk to this game. It gets repetitive fast.
