How to Play
The playing field set against the background of a night forest consists of 5 reels in 3 rows and provides 10 paylines, however, you can change the grid to 5x4 or 5x5 from the very beginning of the game using the Shadow Rows feature. Prize combinations here are created from 3-5 matching low-paying or 2-5 matching premium symbols. You can bet from €0,10 to €100 per spin on any platform or device to try your luck in this game. Betting these sums is possible only when using the standard 3-row option, and as soon as you use the Shadow Rows feature, your bet will be increased by 1.5 or 2 times.
So then, how do you play this spooky, scary slot? After you’ve selected your casino just:
- Load the game
- See what payouts the paytable offers
- Check out how the bonus features work
- Place your bets (using the standard 3-row option)
- All set!
Book of Shadows RTP and Volatility
Book of Shadows is a slot with extreme volatility and adjustable RTP.
Night forest with animal skulls and fog is hardly the safest place to walk. The dark design of this slot machine perfectly reflects its highly volatile nature. Here you have to deal with high risk and adjustable RTP: 96.01% and 94.09%. By the way, the Shadow Rows feature not only increases your bet but also the RTP. The theoretical return will increase as you open more rows: 96.01%, 96.07%, and 96.19%.
Meanwhile, the volatility in this slot, like in most of the Nonlimit City games, is extremely high, which is not the most appropriate option for causal or newbie gamblers.
Theme
We like good horror-themed designs even if they're not about Halloween, and Book of Shadows gives us a good scare in the middle of a spooky forest. Here we encountered creepy cats, eyeballs, and sacrificed animals with a haunting tune playing in the background. Well, definitely a lot of players will love it and we also really like the cartoon/comic style of this game.
Let's see what's going on in the paytable of this bloody slot.
As always, there are regular and premium symbols. Spellbook, girl, cat, goat skull, butterfly, and eye are the most valuable, while bloody playing card suits are low-paying. Also, the game has a special scatter symbol - the spellbook - which is your key to triggering the free spins feature.

Bonus Rounds & Free Spins
Lucky Locks
There is a Lucky Locks bonus feature that is very similar to what Microgaming calls Hyperspins. This feature allows you to lock up to 4 reels after each spin and only spin the remaining unlocked reels. The cost of each spin directly depends on how many reels you have blocked, what symbols are on the blocked reels, and so on. For example, you can block 2 scatter symbols in the hope of getting the 3rd one, and this will of course be worth more than a spin that cannot generate such a potentially lucrative result.
Gamble
Here, as in most "Book of..." slots, you have the opportunity to gamble your win. You can gamble any win obtained in the base game or in the bonus round. The rules are the same as usual: the correct card suit, red or black. You can play this game 5 times in a row if you want, but the winning amount cannot exceed €500,000.
Bonus Wheel
With the Bonus Wheel feature you can win the free spins feature and your chances of winning increase with your bet size but you cannot bet more than 60x the bet. You will see the Wheel of Fortune with a rotating red segment and the size of this segment increases with the size of your bet. With the Bonus Wheel, you can get 10 free spins.
Freespin With Golden Symbol
As soon as 3+ Scatters land on the playing field, the slot will instantly launch the free spins feature and how many free spins you get depends on the number of your rows:
3, 4, and 5 rows trigger 14, 12, and 10 free spins.
Before the start of a feature, as is usually the case in "Book of..." style slots, a special symbol is selected and you have the opportunity to shuffle the deck if you are not happy with the result. However, this can also make the selected symbol worse, and you must accept whatever comes up on the second try. The selected symbol expands to cover the entire reel when it lands and the good news is that the expanded reels don't have to be next to each other to secure a win. The bonus round will be re-triggered when you land no more than 3 Scatter symbols.
Book Of Shadows Demo Play
You don't have to risk real money to try your luck in Book Of Shadows. This gloomy slot machine comes with a demo mode that you can easily use by clicking the play demo button right on this page. In the lower right corner, you will see "Balance: €10000.00” - this is the amount of free virtual coins you can use for betting.
Max Win
Win up to 30,338x the bet.
The maximum you can win in this slot is 30.338x the bet and this is an extremely high max win potential for a high-risk game. It's hard to achieve, but we're sure that on a good day you'll be able to get something like this. For example, during the free spins feature, 5 stacked Goth Girls will bring you 10,000x the bet. Not bad!
Overall Rating
Well, we rarely see a creative take on the hackneyed "Book of..." genre. NoLimit City decided to deviate a little from the path most providers take, and there's a lot more to see here than just an unusual design. This title is literally a dream come true for any Book slot fan who wants to have huge winning potential as well as the ability to change the number of reels. The feature that blocks the reels is smart but can be quite expensive if you decide to block the scatter symbols. The bonus round is the least innovative thing in this slot machine and this fact surprised us as this is where most providers usually take a turn.

Not a fan of mega innovative features. Here you’ll find locked elements, also part of the board is in shadow. Honestly, I had no clue how to unlock them but clicked accidentally and...UNLOCKED! Wonder if I was the only one in such situation.
Another part of the story is high variance. Down streaks can be really costly here. IMO it’s better to play with unlocked reels. Yeah, u pay for it, but chances of hittin FS are hier!
Not bad, but not for me
