Deep in underground mines, 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 super-charged to help you cover more ground. Special crystals boost the machine to reach the deepest jewel veins, and you can expand the machine at any time with ‘BONUS’ drills. Three bonus drills push the machine into Free Spins Mode, while a collection of crystals bring Collection Free Spins with Super High Paying symbols. Jump behind the dwarven digger, golden treasure is waiting to be found!
