Deep underground, hidden treasure glistens in the light of torches. Forget the pick-axe, the dwarven digger goes deeper, hungry for valuable discoveries.
The digging machine is boosted by special crystals and can be expanded at any time using Bonus Drills. Three Bonus Drills push the machine into Free Spins Mode, while a collection of crystals brings Collection Free Spins with Super High Paying Symbols.
