The Smelter is a production building unlocked at experience level 24. Players can have up to five smelters.

It is used to make silver bars, gold bars, platinum bars, iron bars, and refined coal.


The Smelter is a brick furnace, with a chimney, an oven and a mold to pour molten metal or coal into. A casket of ore sits next to it.

The mastered version has a golden star on its basket, as well as copper bricks.


It takes 18 hours or 42 diadia to build each smelter and gives players 21 xpxp when completed. It costs more and more coins to build them:

  • 12,500 coincoin for the 1st one
  • 22,000 coincoin for the 2nd one
  • 31,500 coincoin for the 3rd one
  • 41,000 coincoin for the 4th one
  • 50,500 coincoin for the 5th one
  • Each smelter costs 9,500 coins more than the previous one

Strategy tips

  • Each bar requires 3 units of ore.
  • Producing bars is tied to the Helter Smelter achievement.
  • The Smelter is very hard to master if you do not have five of them.
  • Selling bars is not profitable at all considering the time it takes to make them.
