Congratulations, you have completed all of the current game’s levels and you have entered a new phase of the game. You goal now is to Smelt as much gold as possible so that you can climb the leaderboards to the top. If you tap on the leaderboards icon on the top left of the screen, you can see others who have reached maximum levels like yourself. It should be pretty easy for you to start smelting gold in the smelter, located on your Home Claim, if you have unlocked all of the researches located in the research lab. We will be adding more levels and new features in the near future.
