Theme and Appearance

Visually, Book of Halloween is impressive. The game a standard 5x3 reel set with 10 fixed paylines. The reel set is transparent, which allows you to see the spooky backdrop behind the action. An eerie backing track accompanies the gameplay, which makes the slot even more spooky. Behind the reels, you can see a silhouetted house perched on a hill and a full moon in the sky. Symbols-wise, you'll see pumpkins, gravestones, cauldrons and zombie hands as the high-payers, while the low paying symbols are represented by Q, J, K, A and 10 card suits. Like most slots, Book of Halloween comes with a Wild symbol. In this game, the Wild is represented by the book which can substitute for all standard symbols to help form a winning combination. The book is also used to activate the main feature.

Betting and Prizes

To receive a payout in this slot, you'll need to land two or more matching symbols in combination. As you'd expect, the card suits are the lowest paying symbols while the Halloween-themed icons are the highest paying. The most rewarding symbol is the pumpkin, which pays 1x your stake for two-of-a-kind, 10x your stake for three, 100x your stake for four and 500x for five.

While Book of Halloween doesn't come with a jackpot, you can still win a decent amount of cash. The maximum win is 2,500x your stake, which works out at £250,000 if you're playing with the maximum wager. This is roughly half the potential of the other book slots, but it's still a good amount of money. We expect that people will play for the theme and features more than anything else.

The RTP is set at 96.23%, which is just above average for this kind of slot. The maximum payout in Book of Halloween is 5000x your total stake, which can result in a hefty payout if you're playing with the maximum bet.

Slot Features

Like most slots, Book of Halloween comes with a few bonus features including a Free Spins round. This works similarly to other slots in the book series, so you'll be familiar with it if you're a regular gamer. The game also comes with a gamble feature which offers the chance to double your winnings. Below, we explore these in more detail.

Free Spins

The book symbol acts as both a wild symbol that replaces other symbols and a scatter symbol that triggers the Free Spins round. To activate the Free Spins round, you'll need to land at least 3 book symbols on the same spin. You'll then start the round with 10 free spins – regardless of how many scatters you land to activate the feature. However, the number of scatters on the triggering spin will determine your cash prize at the start of the round. If you land 3 book symbols, you'll win 2x your stake, 4 book symbols will give you 20x your stake, while 5 book symbols will give you the maximum prize of 200x your stake.

Before the Free Spins round is played out, one of the regular symbols will be chosen at random to become the special symbol. This symbol will then expand to fill the entire reel whenever it lands during the Free Spins round.

Gamble Feature

If you're willing to risk your winnings, you can be in with a chance of doubling your payout. The gamble feature is best described as a 50/50 odds game. You need to win more than 5 times your stake to trigger the feature, and you can play to either double your winnings or lose it all.


Overall, Book of Halloween is a stellar addition to the book series. Inspired Gaming has done a great job with the graphics and sound effects, which give the gameplay an eerie vibe. When you're playing with the maximum wager, you can win an impressive £250,000 with this slot. If you're a fan of the book series, Book of Halloween definitely won't disappoint. If luck is on your side, you might just win big!
