There are multiple ways to bring new workers to your mine.

We’ve discussed the first way in the first chapter: just spend some coins to hire a new goblin by pressing the button at the bottom of the screen.

Check the button to see the current level of the goblins for hire and the price for one goblin.
 

The more goblins you hire, the higher their starting level is! But at the same time, the cost of hiring increases drastically. So choose your strategy wisely! Sometimes it’s better to spend gold on your Forge or Shafts instead.

Price is reduced every time a checkpoint is activated and can be further reduced with the Heavy Discount rare card.

Goblin Cannon, located at the right of your Forge, can also help you with the new goblin power.
 
 
It shoots Mystery barrels, which contain different resources, including new goblins! Also, the cannon shoots one goblin barrel every 40 mins.
 

Another way to get more goblins is to win them in the Spinning Wheel.
 


Merge your goblins to get the higher-level miners. Remember that goblins should be of the same level to be merged. For example, you can’t merge a level 1 goblin with a level 2 goblin. You’ll have to combine two 1 level goblins first to get another level 2 goblin.  Also, you do not sum their levels, you upgrade them, so two of 2 level goblins will merge into 3 level goblin, not 4 level one.
 

Higher-level goblins use more advanced tools and destroy rocks way faster!

Also, keep in mind that the number of goblins you may keep simultaneously is limited. You can see your current goblin limit at the top right of the screen. If you reach the limit, you won’t get goblin barrels anymore, so merge some goblins or increase the limit using special cards.
