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.
What if the "Spin" button is greyed out?
The ads are provided by your local ad provider. If the "Spin" button is grey, it most likely means that there are no ads to show at the moment, or your Internet connection is unstable.
Here are a few steps that may help:
1) Wait some time for the ad limit to reset.
2) Check if your internet connection is stable or try another network.
3) If you’re using an Android device, clear the Google Play cache.
