Heart of Earth Xmas

Heart of Earth Xmas review

Heart of Earth Xmas is the Christmas version of Heart of Earth, an underground adventure about a journey to the core of the planet that Swintt describes as a proven land-based classic across Europe. Released on 21 December 2022 in the SwinttPremium line, it keeps the original's lean setup: a 5×3 grid with just 5 paylines, medium volatility and a standard RTP of 94.91%. The provider also publishes a hit frequency of 16%, which means a winning spin roughly once every six spins - a useful figure that most studios do not share. The bonus is a book-style free spins round where a randomly chosen Lucky Symbol can expand across whole reels.
