Features Castle of Fire by Pragmatic Play uses a 6x3 grid with 729 ways to win, where matching symbols from left to right create payouts. The base game features crowns, wolves and tigers, while a golden Mystery symbol can appear on any reel and transform into a random paying symbol, excluding the Scatter.
The Scatter symbol is shown as the castle and can land anywhere on the reels. Three or more Scatters trigger the free spins bonus round, which starts with 12 free games. During this feature, Mystery symbols become sticky and stay on the reels until the round ends, with each one transforming into one, two or three instances of the same random paying symbol after each spin.
Players can use the demo version to play for free and practice before playing for real money. The game has high volatility and an RTP of 96.01%, with the free spins bonus also available in the base game through a bonus buy option at 100x the bet.
