If you are into exploration and adventures, then you’ve probably come to the right place. Heart of Earth is an online slot game made by Swintt with a thrilling story like this. The graphics of this game is attractive because the symbols are of high quality, the reels are dark, and in the background, you can see an image of the underground.

Heart of Earth is played on 5 reels and has 5 paylines. In addition to five colorful, stylized playing cards, this online slot has a few original basic symbols like a compass, some sort of a statue, a drilling machine that helps you explore the core of our planet, and the adventurer himself. Watch out for the shiny compass-like symbol. This is a symbol that has special powers. For starters, this is a Scatter symbol. Get three or more of these scatters anywhere on the reels if you want to get a cash reward. A combo like that will also deliver 10 Free Spins. During this mode, one of the basic symbols is turned into an expanding symbol that pays prizes in any position. Additionally, this special symbol acts as a wild symbol – it replaces all symbols when needed.
