Book of Wolves is an online video slot made by game designer Spinomenal. It has RTP ranges and suggests low variance. The game is played on 5x3 reels set with 10 bet ways. Features include the Book mechanic, free spins, wild and scatter symbols and a buy option. 


Book of Wolves is an exciting 2022 online slot from game maker Spinomenal. The game is presents on a simple 5x3 reel set which has 10 bet ways that pay left to right.
There is a book wild symbol which also acts as a scatter. It replaces any other symbol on the reels to help to form winning combinations and also pays when it forms a winning line on its own. When a minimum of three appear on the screen it triggers 10 free spins, and this feature can re-trigger a further ten free games. Three wilds pay x2, four pay x25 and five offer a x250 reward.

Prior to the free spins round players get to spin a wheel to decide on a symbol other than the wild, which will appear as an expanded symbol during this phase of the game, filling the reel it appears on. This will only happen of a wining line can be formed.

Apart from the wild there are nine paying symbols. The top four are the wolf, the bear, the moose and the owl. There are also five playing card symbols from ace to ten.

Fans of this designer’s work will find many more Spinomenal demo slots here at Slots Temple to try out if you are thinking of visiting an online casino to play the game for real.

Theme, Graphics and Soundtrack 

In a snow-swept wilderness wild creatures circle around whilst an orchestral soundtrack plays in the background in this slot from Spinomenal. As we would expect from this designer, the symbols are beautifully crafted and the reel set is an iced block with winning symbols framed in snow. 

In the top left above the reels is a features box for quick reference, and the number of lines in play is highlighted on the right.

The game maker has also provided the player with an easy to read and use dashboard.

If the tug of the wilderness appeals to you, why not take a look at Blueprint Gaming’s Megaways Wolf Legend, which displays high variance and 117649 pay lines across six reels?

Book of Wolves Free Spins Bonus Features 

Three or more book wilds will trigger 10 free spins, and this feature can re-trigger.

Before the free games begin players get to spin a wheel containing all the symbols other than the wild to select a symbol which will expand during the free spins.

The expanded symbol which will fill the reel will only trigger if a winning line can be formed.

Book of Wolves Review 

This is a beautifully designed game from Spinomenal and is a great addition to their portfolio. The expanding symbols in free games help to create lots of new winning lines, and if you are lucky enough to have a top-paying symbol chosen, you can swell your bankroll significantly.

The book symbol is very powerful, acting as both a wild and a scatter, and is a top payer.

It is disappointing to see RTP ranges in operation, and the player will have to check at online casinos to get the best values before choosing where to play.

The game has a decent bet spread, but the maximum win and the low variance may not suit everyone.
