Ready for tunnels of underground fun? Our hero, Digger T. Rock, is mining for a legendary lost city - and he needs you to dig in and help out! Burrow through mysterious caverns, each one a "mine-boggling" maze of unknown dangers. Battle fierce foes like dinosaurs, ghouls and cranky cavemen with clubs. Collect rocks, dynamite, ladders and jewels, and use them wisely. Dig deep to uncover secrets, like how to open cavern doors - and how to reach them before they slam shut! Dare to dig down to the deepest, most dangerous cavern... and discover what lies beyond!
