Spin the wheel to get rare rewards! Tap the spinning wheel icon at the bottom of your screen to try your luck.

 

 

You get one free spin daily and five additional spins that could be unlocked by watching ads. You get one additional ad spin every 2 hours.

 

The rewards are time potions (please note, they will take effect immediately, so make sure your goblins have something to dig and your shafts are automated) and high-level goblins. Additional rewards are gems in the main mines and blue elixirs in the event mines.
