How the Game Plays

Howl-O-Ween transports players to a fog-drenched Victorian London, where supernatural secrets lurk within the shadows of a 5x3 grid. This high-volatility slot by Rival Gaming features 243 ways to win, utilizing a combination of traditional royal icons and thematic symbols like oil lamps, leather-bound books, and amulets. The atmosphere is defined by gothic aesthetics and a blood-red moon that signals the transformation of man into beast. Winning combinations are formed by landing matching symbols on adjacent reels starting from the leftmost side.

Full Moon Fury & Werewolf Wilds

The central mechanic revolves around the Werewolf Wild, which appears on the reels to assist in creating winning combinations. When a Wild lands on the third reel, it triggers the Full Moon Fury feature, causing the symbol to expand and fill the entire column. This transformation awards a re-spin with the expanded wild locked in place. Furthermore, the werewolf symbol often carries a 2x multiplier that applies to any winning line it completes.

Howling Riches Hold & Win Bonus Explained

Landing six or more Blood Moon prize symbols triggers the Howling Riches Hold & Win Bonus. The standard reels are replaced by a specialized grid where only prize symbols and blanks appear. You begin with three re-spins, and each new prize symbol that lands resets the counter while remaining sticky. This round is the gateway to the game’s four fixed jackpots: Mini, Minor, Major, and the Grand Jackpot. Filling the entire grid with symbols awards the top prize, contributing to the maximum win potential of 20,255x. A Bonus Buy option is available for those wishing to enter this feature immediately.
