How the Game Plays

Heart of Earth, developed by Swintt, takes players on a subterranean expedition deep into the planet's core. The game utilizes a classic 5-reel, 3-row layout with a focused set of 5 paylines. The aesthetic blends elements of steampunk with traditional adventure, featuring a brave explorer, drilling machinery, and golden compasses as its primary symbols. Wins are achieved by landing matching symbols from left to right, with higher-tier symbols like the explorer offering payouts for just two of a kind.

Free Spins Explained

The core attraction is the Free Spins feature, triggered by landing three or more Glowing Crystal symbols anywhere on the reels. These symbols function as both Wilds and Scatters. Upon activation, players receive 10 free spins. Before the round begins, a random "Lucky Symbol" is selected from the standard paytable.

Expanding Lucky Symbol Feature

During the bonus round, if the chosen Lucky Symbol appears in sufficient numbers to form a win, it expands to cover its entire reel. These expanded symbols pay on all active lines, even if they are not on adjacent reels. This mechanic can potentially fill the entire screen with the same symbol, leading to the game's highest payout potential. The feature can be retriggered by landing additional Scatters during the round, and modern versions also offer a Bonus Buy option for direct entry.
