Book of Abyss Slot Real Money Review – Bonuses, RTP and How to Play

Introduction to Book of Abyss

Book of Abyss is a casino slot game developed by Just Slots, immersing players in a world filled with demons and expanding symbols. This title is part of the popular “Book of” series, which has its roots in the 2005 release of Book of Ra, often referred to as the founding game of this genre. Book of Ra established a template for lucrative Expanding Symbols. Fast forward to 2016, the release of Book of Dead further popularized the genre with modern Expanding Symbols and Free Spins, paving the way for numerous similar games. In this context lies Book of Abyss, which adopts a trusted formula centered on Expanding Symbols during the Free Spins bonus game, complemented by Multipliers and Gamble mechanics to enhance its volatility and offer a chance for a max win of 150,000 times the bet.

Book of Abyss successfully adheres to the appealing characteristics of the “Book of” format, enabling players to accumulate wins within a demon-themed Halloween setting. If this has sparked your interest, be sure to explore the game’s demo.

Theme, Gameplay & Payouts

Book of Abyss features a layout consisting of 5 Reels, 3 Rows, and 10 Paylines. Players can place bets ranging from a Minimum of 0.1 to a Maximum of 5. The game boasts a high RTP of 98.03%, although lower RTP variants are available at 96.36%, 94.33%, and 92.42%. With a hit frequency of 26% and a medium/high volatility, wins occur relatively often, and while they may not always be significant, players have the chance to achieve the impressive max win of 150,000X the bet.

Set in the underworld, players are greeted by the Queen of demons, Abyss, who acts as the highest-paying symbol in the game. The playing grid showcases her castle, flanked by gargoyle statues and various servants appearing on the reels. The game is compatible with most desktops, tablets, and mobile devices.

The lower-paying symbols consist of several runes, including yellow, green, blue, and red, offering payouts of 4X to 5X the bet for five identical symbols. The medium-paying symbols include candles, rings, and a heart, which pay out 12.5X to 20X for five matching symbols. The higher-paying symbols are the skeleton knight, demon servant, and Queen of Demons Abyss, paying 75X to 150X for five of the same symbol. The only special symbols present are Wild Symbols, which provide additional effects, discussed further in the next section.

Special Features & Mechanics

What is the max win in the slot Book of Abyss?

Players can win up to 150,000X the bet.

What features are available in the slot Book of Abyss?

The available features include Wild Symbols, Free Spins, Gamble, Feature Buy, and Ante Bet (Hot Spin).

Wild Symbols

Wild Symbols assist in forming winning combinations by substituting for all paying symbols.

Free Spins

Landing 3, 4, or 5 Wild Symbols triggers the Free Spins feature. Before the bonus game commences, one Expanding Symbol and a Multiplier, ranging from 1X to 100X, are selected. Additional Wild Symbols can enhance the minimum Multiplier—4 Wild Symbols guarantee a multiplier of 2X or higher, while 5 Wild Symbols offer a multiplier of 10X or higher. The chosen Expanding Symbol expands each time it contributes to a winning combination, not requiring adjacent symbols to win.

During the bonus round, hitting 2, 3, 4, or 5 Wild Symbols in a single spin retriggers the feature, awarding an additional 3, 10, 15, or 20 spins. Each time, a new Multiplier ranging from 2X to 100X is selected and added to your current Multiplier.

Gamble

Prior to the Free Spins feature, players have the option to Gamble using three different Wheel Options. The choices include the Special Expanding Symbol for a chance at a higher-paying Symbol, the starting Multiplier to potentially upgrade it, or the option to seek the highest-paying symbol paired with the highest starting Multiplier. Players can continue to Gamble for as many spins as desired until securing the maximum Expanding Symbol and Multiplier, or until they lose, ending the Free Spins.

Feature Buy

Players can directly access the Free Spins bonus game through the Feature Buy option, priced according to the current bet:

100X = Grants the Free Spins feature with 3 Wild Symbols.

300X = Grants the Free Spins feature with 4 Wild Symbols.

1,250X = Grants the Free Spins feature with 5 Wild Symbols.

Ante Bet (Hot Spin)

By activating the Ante Bet, players can increase their chances of triggering the Free Spins feature, though this adds 300% to the current bet while introducing extra Wild Symbols to the reels.

Final Thoughts on Book of Abyss

Just Slots has opted for a traditional approach with Book of Abyss, presenting features and gameplay loops reminiscent of games seen nearly a decade ago, with minimal innovation. While this aligns with the trends in this genre, where many titles opt not to diverge from the conventional, the game thematically shifts away from the usual Egyptian motifs, making it a fitting seasonal Halloween release. However, the visual style lacks vibrancy and depth, contributing to a somewhat bland aesthetic.

The game’s statistics are notably strong, featuring a high RTP of 98.03%, a hit frequency of 26%, and a considerable max win of 150,000 times the bet. Yet, one might question if these attributes suffice to redeem gameplay that resembles earlier titles. While we appreciate the Book of genre, there is a desire for innovation rather than repetitive formulas that may show signs of wear.

In the base game, players may find limited opportunities to secure wins; Wild Symbols are the primary feature while playing. Although many paying symbols offer solid payouts, the gameplay can feel mundane if wins do not occur frequently, with scarce Wilds leading to minor wins. The bonus game introduces typical Free Spins with Expanding Symbols, creating potential for exhilarating spins with substantial multipliers and retriggers, yet this gameplay remains familiar. The Gamble mechanic stands out as a significant departure from Book of Dead, allowing players to pursue larger multipliers and the highest-paying symbol, adding a layer of risk that can be worthwhile.

In summary, Book of Abyss is a slot game characterized by classic “Book of” features and mechanics, all set against the backdrop of the underworld.
