Our House Of Doom Slot Review

This dark heavy metal-themed slot delivers high volatility gameplay with an RTP of 96.11% and maximum wins up to 2,500x your stake. The standout feature is the expanding wild system where randomly highlighted reels trigger full wild reels when wilds land, with even more highlighted reels during the 10 free spins round. While the 2,500x max win is modest for high volatility, the dual bonus system—combining a pick-and-click feature with free spins—adds variety for players who enjoy rock aesthetics and aren't deterred by a heavy metal soundtrack.
