Overview of Book of Shadows

Book of Shadows is the latest slot from the developers at Nolimit City who are branching into the “Book of” slots with this first attempt. It appears that there is some type of agreement that all developers should offer at least one “Book of” slots in their portfolio. This attempt by Nolimit's shows that they have certainly applied their best creativity and although the must-have expanding symbols are present the rest of this game is unique and breathes fresh air into this genre.

As soon as you see this slot you will realise that it is not the usual “Book of” slot as instead of being set amidst the warm sands in Egypt but somewhere a lot colder. This slot appears to sit within the woods in an outdoor Sleepy Hollow. There is an eerie soundtrack whilst fireflies float across the screen and in the background wolves can be heard howling interspersed with owls hooting, which gives an ambiance where you could really believe the headless horseman is due to come crashing through the trees!

Game Play Information

Playable on all devices you can bet from a minimum of 10p per spin up to a maximum of £100 per spin which is the cost when you play at the default 3 row setting. It is possible to activate four or five rows, all you need do is click on the play grid, however if you opt for four or five rows your bet increases by 1.5x or 2x, respectively. The return to player is also dependent on the row amount you choose, and 3 rows equate to 96.01%, 4 rows 96.07% and 5 rows equals 96.19%. Regardless of the formula you choose the volatility is rated by the developers as highly volatile 10/10 and advertised as “Extreme.”
The rules are standard, and wins are created by landing the same symbols from left to right starting from your first reel. Bear in mind that the more rows in play the more pay lines you have to play with this means that your 3, 4, or 5 rows provides 10, 15 or 20 Shadow Rows, which is what they are called in this slot.


There are 10 regular symbols which make up the pay table, with the lower paying symbols being made up of the usual playing card symbols 10 through to Ace with the higher paying symbols consisting of an eyeball, a butterfly, a goat's skull, a purple cat, and a female goth. With the lower paying symbols, you must land at least three of the kind to create wins, whilst you only need to land two of a kind with the higher paying symbols. The wins from the higher symbols are sizeable when you manage to land five of a kind and will pay from 50x to 500x the stake. The wild symbol as with all “Book Of” slots takes on the persona of the scatter too.

Book of Shadows: Features

Although the free spins complete with expanding symbols is the most sort after feature, there are other features on offer such as Lucky Locks, Gamble 50/50, and a Gamble Wheel of Bonus on offer. Lucky Locks is like the Hyperspin feature from Microgaming and gives you the opportunity to lock your reels in place for an additional bet. This feature is available after every spin in the main game, and you can lock up to four of your reels in place. The additional bet amount is dependent on the reel, the symbols the reels contains etc. If you get lucky you could land the chance to lock two scatters and a re-spin, then hope to land the third.
Every “Book Of” comes complete with the chance to gamble your winnings and this is where the 50/50 gamble feature steps in and it is available after landing wins in the base game or after the free spins feature. This is a simple feature that sees you picking a red or black card to double your wins or lose the lot. You can activate up to five gambles in a row providing your win does not exceed £500,000.

The Wheel of Bonus feature sees you gamble to win free spins providing that your winnings are not more than 60x your bet. The wheel will appear with the highlighted segment spins, and the size of this depends on your win amount. If you land in the segment you will be rewarded with 10 free spins at your current row height.
Finally, there is the free spins feature which is activated by landing three or more of the book symbols in view on your game screen. Three scatters reward you with 10 free spins at the current height of your rows, however, you can decrease or increase the number of rows to win free spins. Before the feature starts a golden symbol is chosen at random and if you are not happy with the symbol you can reshuffle the symbols once to hope you are provided with a better symbols but remember that this can be a disadvantage and you may get a lesser symbol second time around.
When you are playing your free spins, the random gold symbol can expand and cover the entire reel after any wins have been calculated. The expanded gold symbols pay all wins from any position. The symbols you will want to land are the five goth girls first as these will reward you with 10,000x your stake. Finally, if you land three or more of the book scatters on a free spin reactivates the feature.

Theoretically, the bonus game triggers after 154 spins of your reels however, if you cannot wait you can use the buy in feature which is referred to as the Nolimit Bonus and this will cost 60x, 90x, or 120x your bet for 10 free spins complete with 3, 4, or 5 rows respectively.


The designers at Nolimit City has taken the “Book Of” genre and turned it upside down. Usually developers simply tweak one aspect of the game before release, however apart from the expanding symbols which is a core feature and therefore naturally must be included the rest of this slot is new providing a totally new game. It is fair to say that not everyone will appreciate this slot and it cannot be lumped in with the Ra-style imitators.
Book of Shadows provides plenty of options and it is the type of slot that can begin more appealing the deeper you get into it. The theme is unusual, and the slot has a clever design and plenty of opportunities for those who are happy to adjust the settings and get to know the slot in and out. This is yet another example of how Nolimit can demonstrate their creativity and excellent to provide a well-worn format and make it unique.
