Without any data to back it up, we feel comfortable in saying that expanding symbols is the most common feature in the industry. Perhaps sticky wilds and progressive multipliers are up there, but “Book of” slots are released almost daily. Thus, there’s no immediate excitement when seeing another one pop up on our radar, but Book of Shadows changed that quickly. Not only is it a thrilling setting, but NoLimit has made sure to innovate on this commonly used mechanic. Allowing players to choose the amount of rows is a brilliant addition, giving us a sense of control in how we want to play the game. Furthermore, it’s great to be able to gamble for Free Spins and not only the standard “double the win”. Nonetheless, the game is, in its core, a book game, so we’re not seeing something completely new here. Book of Shadows by NoLimit City is a standard book game in its core, but made very interesting by some interesting features.

This very creepy slot is very well designed. The theme won’t be to everyone’s taste but if you like the horror genre then the Book of Shadows slot should appeal. The soundtrack in particular is chilling. Book of Shadows has similarities to Play ‘n GO’s Book of Dead (special expanding symbols) but you can exchange the symbol if you don’t like the one you’ve landed (basically you gamble for a higher value symbol). However, this game is also high variance which can mean lengthy lean spells. Saying that, Book of Shadows blows Book of Dead and Novomatic’s Book of Ra Deluxe out of the water with top payouts of 30,338 x your total stake. The 2 mentioned offer 5,000 x stake max wins. If you enjoy volatile, horror-themed slots, Book of Shadows ticks all the right boxes. For the bigger payouts, you will need to choose playing with 5 rows and 20 paylines. Just be careful as it’s classed as ‘extreme’ by Nolimit City on the volatility front. You should also try other Nolimit City slots with El Paso Gunfight and Fire in the Hole offering 44,440 x stake and 60,000 x stake max wins respectively.

The incremental additions found in Book of Shadows offer a thrilling take on the original formula, resulting in another quality game from Nolimit City.
