Time potions help you to instantly skip some time in the game and get the profit!

 

To access your time potions or buy some, enter the in-game Shop (a chest icon at the bottom of the screen), and scroll down to the "Time Potions" section:

 

• Your time potions are shared between the main game and events;
• Small time potions earned from the Spinning Wheel are used immediately. They don't go to your inventory;
• Make sure to place your goblins near rocks before using a time potion, or it'll be wasted!
