How the Game Plays

Heart of Earth Xmas is a festive holiday reskin of the original adventure slot by Swintt. The game moves the action from deep underground to a snow-covered landscape, though it retains its classic "Book of" style mechanics. Played on a standard 5x3 grid with 5 fixed paylines, wins are achieved by landing matching symbols from left to right. The higher-paying symbols, including Santa and various expedition tools like the compass and drill, award payouts for as few as two of a kind. The central figure is the Portal symbol, which serves a dual purpose as both the Wild and the Scatter.

Free Spins Explained

The main highlight of this slot is the Free Spins feature, triggered when three or more Portal symbols appear anywhere on the reels. This awards 10 free spins. Before the round begins, a random symbol is selected to act as the "Lucky Symbol." During the feature, this symbol can expand to cover an entire reel if a winning combination is possible. These expanding symbols pay out on active lines even if they are not on adjacent reels, provided the minimum number of symbols is present.

Gamble Feature Explained

Like many titles in the Swintt Premium collection, the game includes a gamble option available after any winning spin. This allows for a double-or-nothing game where the objective is to correctly guess the color of a face-down playing card. Successfully choosing Red or Black doubles the win, while an incorrect guess results in the loss of that spin's payout.
