The Howl-O-Ween slot machine has an RTP of 96.25%.

The first feature of the Howl-O-Ween online slot is the wild, which is represented by the game’s protagonist. This substitutes for all regular symbols within the game (except the scatter) to create or enhance winning paylines.

When landing on reel 3, the Howl-O-Ween slot machine’s wild expands to cover the entire reel and becomes a werewolf that applies a 2x multiplier to any win it forms part of. It then locks into position and awards a free respin, where all other reels spin for a chance to win more prizes.

Land six or more Prize Symbols, represented by the Blood Moon, to trigger the Howl-O-Ween slot’s Hold & Win Bonus feature. You’ll be given three respins that reset each time a new Blood Moon locks into position. Blood Moon symbols carry a prize of between 1x and 10x your stake, or the Mini, Minor, or Major Jackpot prize. The round continues until there are no respins left or until all positions are filled with Prize Symbols, at which point your prize is collected and paid out. If you end the round due to the latter, you’ll win the Grand Jackpot prize, which is worth up to 600,000 coins.

You can get to the Howl-O-Ween slot’s Hold & Win Bonus feature faster when clicking on the Bonus Buy button. Simply confirm your purchase and you’ll be given an automatic spin with guaranteed Prize Symbol drops.
