United Kingdom (EN) About Howl-O-Ween from Rival Gaming
Howl-O-Ween is a werewolf-themed slot that is developed by the renowned software provider Rival Gaming, and the game was released in September of 2025. The grid uses 5x3 reels across the vintage Victorian London setting, and it offers up to 243 different ways to win, which is great. Also, their main in-game features are the bonus buys, expanding wilds, re-spins, and hold-and-win.
While playing with real money, players can spend a minimum amount of $0.30 per spin and up to a maximum amount of $30 per spin. If you ask us, we find this range to be pretty decent as it is suitable for all the budget-oriented players as well as the high rollers. This game also comes with an impressive RTP of 96.25%, making it a value pick amongst the heaps of slot games out there.
As you enter this game, you’ll see that most of the action takes place within a spooky 19th-century atmosphere with lots of royal buildings all around. However, the main attraction here is the high-paying symbols, which are the oil lamps, blood diamonds, secret book, and hats—wait, bats flying around too frequently. The low-paying symbols include A, K, Q, J, and 10.
Besides that, things get more exciting when you see a werewolf transforming into a half-man on the reels. This indicates that the expanding bonus wilds are triggered, which can lead to more bonus chances and extra winning opportunities. You can also pay an additional amount to quickly activate the hold-and-win feature and enter into the howling riches, and then simply aim for the mini, minor, major, or grand prizes on the move.

When these re-spins are used, the prize symbols will lock in their place to boost the winnings. After that, the awards will be credited in the form of a hold-and-win bonus. The best rewards appear when you land on 6 or more blood moon symbols on the reels in one single spin.
Wild Symbols
On the other hand, the job of the wild symbols is also to create better winning combinations on the reels. However, it will replace all the other symbols except for the scatter symbols. Also, only the highest-paying symbols will be multiplied as rewards after the next spin on the reels.
Sticky Expanding Wilds
When you see a werewolf wild symbol land on reel 3 and create a winning combination, it will expand to fill the reel. That’s when the werewolf wild symbol expands and transforms into a half man and half werewolf, and then this expanding wild symbol will lock in place for the free re-spins.
