Dwarf Mine is an addictive RPG game where you lead a kingdom of dwarfs and have to mine and mine and mine to pay of your Kingdom's debt of 10 billion gold and hopefully find some mythical gems! Digital purchases: 100% of Dwarf Mine can be enjoyed entirely for free. But, if you'd like to get through the game more quickly, we offer purchases of an energy drink, a consumable item that enables your dwarves to complete mining faster. If you choose to use the energy drink, Mining time will be cut in half. (Purchasing is currently only available in certain countries.)
