Book of Abyss Slot Review
The daring & dazzling Queen of Demons welcomes you to her wicked realm, where laughter lingers in the shadows & fortune gleams in the dark. Book of Abyss from Just Slots has us embracing the dangers of the Underworld as we explore the playful side of darkness, for a chance to win up to 150,000x your bet.
Beneath its doom & gloom exterior, Book of Abyss shines bright for its Book Multipliers, Expanding symbols, & hair-raising Free Spins mode. If it’s not obvious by now, Just Slots is taking the highly popular Book mechanic out for a spin, ticking off another ‘first’ for the rising studio.
There are many Book-inspired slot releases worth mentioning, but it would be rude to leave out the two games that really brought the mechanic to light. Book of Dead and Legacy of Dead are hidden gems from Play’n GO, still very much loved & acknowledged by players today.
While Book of Abyss doesn’t quite fit the bill of an Egyptian-themed slot, it does resonate with Nolimit City’s Book of Shadows, which also happens to feature the Book mechanic, if you hadn’t guessed from its title.
For us, we’re always looking for an excuse to join the dark side, and Book of Abyss definitely ticks that box, but will the risk be worth the reward?
With a fixed RTP of 98.03% (at its best) and a mid-high volatility score, this game can produce wins worth up to 150,000x your bet….yes, you read that right! Whilst we wrap our minds around that impressive figure, let’s take a sneak-peek into the game’s features & mechanics, to see if it really is as dark as it seems..
Base Game & Features
Book of Abyss is the latest instalment from Just Slots, consisting of 5 reels, 3 rows, & 10 fixed pay lines. Paytable symbols create winning combinations when 2-5 matching symbols land on adjacent reels, starting from reel 1.
The highest-paying symbol falls to the Queen of Demons, followed by 2 additional Characters, Hearts, Handcuffs, Candles, & 4 Satanic Tiles. Once a winning combination has been obtained on the reels, a fixed payout between 0.3x and 150x your bet is awarded.
Additionally, Book Scatters act as Wilds on the reels, substituting for all symbols, except Expanding symbols, when completing a winning combination. Book Scatters pay 2x & 150x your bet when 2-5 land on the reels during a spin.
Book of Abyss: Free Spins
The Free Spins mode triggers when 3, 4, or 5 Book Scatters appear anywhere in the base game, awarding 10 Free Spins.
Before the round begins, a random high or low-paying symbol is chosen to become the Expanding symbol. Additionally, a random Multiplier between x1 and x100 is selected, depending on the number of triggering Book Scatters:
- 3 Book Scatters: Awards 1 Expanding symbol + a random Multiplier
- 4 Book Scatters: Awards 1 Expanding symbol + an initial Multiplier of x2 or higher
- 5 Book Scatters: Awards 1 Expanding symbol + an initial Multiplier of x10 or higher
Once the Expanding symbol & Multiplier have been applied, players will then enter a special Gamble Mode, where the Expanding symbol & Multiplier can be gambled individually or together. Of the 3 Gamble Wheels, only 1 can be used at a time, so choose wisely.
If the highest outcome is achieved on either Gamble Wheels, the Free Spins mode will begin. Alternatively, if any of the Gamble Wheels are unsuccessful, the player returns to the base game, empty-handed.
During Free Spins, each instance of the Expanding symbol will fill the entire reel it is currently on, but only when it creates a winning combination. Expanding symbols do not need to be adjacent to each other on the reels to award a payout.
Before each expansion payout is awarded, regular pay lines are evaluated first. Once all expanding symbols have filled their respective reels, the total payout is multiplied by the available Multiplier.
Landing 2, 3, 4, or 5 Book Scatters on the reels awards a further +3, +10, +15, or +20 Free Spins, respectively. Before the additional spins are awarded, a new Multiplier is selected between x2 and x100, which is added to the current Multiplier.
Hot Spin & Bonus Buy
Players may purchase any of the following Hot Spin & Bonus Buy options:
- Hot Spin: For an extra 300% of your current bet, the Hot Spin feature adds more Book Scatters onto the reels (94.33%)
- Free Spins: Instant access to Free Spins with 3 Book Scatters for 100x your bet (94.31%)
- Free Spins 2: Triggers the Free Spins mode with 4 Book Scatters for 300x your bet (94.31%)
- Free Spins 3: Guaranteed entry into Free Spins with 5 Book Scatters for 1,250x your bet (94.33%)
The maximum win potential for Book of Abyss is 150,000x your bet. If a single session reaches this figure, the current mode ends, and the qualifying amount is applied to your total balance.
Our Honest Verdict
Book of Abyss is a classic Book slot in many ways, it’s the gameplay that you know and love, the ripple yet felt by Book of Ra’s influence across the industry, but with a few tweaks, as per Just Slots’ style.
Just Slots seemingly loves super high volatility, which is why Book of Abyss comes packed with a stunning max win of 150,000x, something few others are doing.
How is it possible, you ask? Through the absolutely mammoth 100x multiplier on the Free Spins round, and a good symbol to go with it. It’s not an easy game, not forgiving, and nail-biting when you face those brutal gamble wheels. Either gamble up the multiplier and symbol separately, or together, if you fancy your chances. It requires some serious minerals to gamble, especially at the cost you’re facing for some of the better buys.
Strip back its layers and it’s a book slot through and through, and an enjoyable one at that. Play it the way you remember it, with the humble values and no multiplier, or gamble gamble gamble, just don’t hate on the game if you lose the bonus, the big red segments on the wheel is a warning that should be heeded sometimes.
Just Slots brings a whole new meaning to the Book mechanic – we can’t wait to see if a max win emerges.
