About Book of 99

This section introduces the Book of 99 online slot game. It is a game from developer Relax Gaming. The game draws inspiration from the story of Homer’s Odyssey, an ancient tale of adventure. Scholars place its creation around 700 BC. The narrative follows the figure Odysseus and his journey, including the use of the Trojan Horse which ended the war in Troy.

Book of 99 Slot Overview

The game from Relax Gaming uses this history as its base. It joins other games in the ‘Book’ series, offering familiar mechanics with new additions. Book of 99 operates with 5 reels, 3 rows, and 10 paylines. Bets range from a minimum of 0.10 to a maximum of 100. A notable aspect of this game is its RTP (Return to Player) of 99.00%. The game shows high volatility, a hit frequency of 29.83%, and the most a player can win reaches 12075 times the bet. As expected from a ‘Book’ game, it has expanding symbols, active during free spins when 3 or more Wild symbols land. A Collection function adds another way to get free spins: collecting 99 Wild symbols also triggers free spins. The game offers these features: Wild Symbols, Free Spins, Expanding Symbols, and Collection.

Book of 99 Game Information

The game presents an ancient Greek look. Buildings from Greece’s past appear in the background. Large columns frame the play area. Figures from Homer’s story land on the reels with accompanying music, creating the mood. The developer aimed for broad player access; Book of 99 works across devices. Mobile phone users can easily begin free spins by collecting 3 or more Wild symbols. Players looking to play slot games will find this title works well on smaller screens.

Low value symbols use the forms of 10, J, Q, K, and A, decorated with jewels. Landing at least 3 matching symbols on adjacent reels from the leftmost side results in a win. High value symbols include Odysseus, a figure in a purple hood, the Siren, and the Cyclops. These symbols begin as 1×1 size. With the expanding reel feature, a chosen symbol can grow to cover the entire reel. There are 10 different symbols in total. The last is the Wild, shown as a book. Having fewer symbols can be a plus, as win lines may form more often. This game holds secrets within its book symbol.

What features are in the Book of 99 game?

The game includes Wild symbols, free spins, expanding symbols, and a collection function.

Wild Symbols

This symbol helps create more win lines on the reels by substituting for all other symbols. It also acts as the scatter symbol. Landing 3 or more of these symbols starts the free spins mode.

Free Spins

Free spins are a main part of the game. Landing 3 or more Wild symbols triggers this function, giving the player 10 free spins. If 3 or more Wild symbols land again during these spins, the player gains another 10 free spins.

Expanding Symbols

Before free spins start, the game picks one symbol randomly. When this symbol lands on the reels during free spins, it expands to cover the entire reel. These symbols can form win lines even if they do not land next to each other on consecutive reels.

Collection

Much of the action takes place during free spins. These are activated by landing 3 or more scatters. The Collection function offers another way to start free spins. In the base game, Wild symbols that land are gathered. Collecting 99 Wild symbols grants access to the free spins. The game calculates the average bet based on all spins used to collect the 99 Wilds, and uses this for the free spins round.

F.A.Q.

What is the Book of 99 slot game?

The Book of 99 is an online slot game developed by Relax Gaming. It draws its primary inspiration from the epic tale of Homer's Odyssey, an ancient Greek narrative that is estimated to have been created around 700 BC. The game incorporates visual and thematic elements related to this legendary story, focusing on the adventures of the hero Odysseus and referencing iconic parts of the myth. As part of the popular 'Book' series of slots, it brings familiar gameplay mechanics associated with this genre, such as expanding symbols during free spins, while adding its own unique twists, most notably the Collection feature, making it a distinct title with a strong mythological theme.

What are the basic mechanics of the Book of 99 slot?

Book of 99 is structured with a standard grid layout consisting of 5 reels and 3 rows, which is a common configuration for many online slots. It features 10 fixed paylines on which winning combinations can be formed. Players can adjust their bet size, with options ranging from a minimum of 0.10 credits up to a maximum of 100 credits per spin. One of the most remarkable aspects of this game is its exceptionally high Return to Player (RTP) percentage, which stands at 99.00%. The game is also characterized by high volatility, suggesting that while payouts may be less frequent, they have the potential to be quite large when they occur. The text also indicates a hit frequency of 29.83%, providing insight into the rate at which winning spins might land.

What are the main bonus features in Book of 99?

The Book of 99 slot incorporates several key bonus features that define its gameplay and potential for wins. The primary features include Wild Symbols, which are represented by the book icon and act as both substitutes for other symbols to help complete winning lines and as Scatter symbols. Landing three or more Wild/Scatter symbols triggers the Free Spins bonus round. Within the Free Spins, the Expanding Symbols feature is active, where a randomly selected symbol can grow to cover entire reels, potentially creating significant wins. Additionally, the game includes a unique Collection function, offering an alternative method to trigger the Free Spins by gathering Wild symbols in the base game, adding an extra layer of anticipation to every spin.

How do I trigger the Free Spins feature in Book of 99?

Free Spins in Book of 99 can be activated through two distinct pathways, providing players with more opportunities to access the bonus round. The traditional method, common to 'Book' style slots, is achieved by landing three or more Wild symbols (the book symbol) anywhere on the reels during the base game. Successfully landing 3 or more triggers an award of 10 free spins. The alternative method is through the innovative Collection feature; by accumulating 99 Wild symbols over any number of base game spins, the Free Spins feature is automatically triggered. This also awards 10 free spins. Furthermore, landing three or more Wild symbols during an active Free Spins round will re-trigger the bonus, granting an additional 10 free spins.

What is the Collection feature in Book of 99?

The Collection feature is a standout mechanic unique to the Book of 99 slot, offering an alternative pathway to its highly sought-after Free Spins round. In the base game, every Wild symbol that lands on the reels is actively collected and added to a meter visible to the player. This meter tracks the progress towards triggering the bonus. Once the player has successfully gathered a total of 99 Wild symbols over their consecutive spins in the base game, the Collection feature automatically initiates the Free Spins bonus round. The game calculates the average bet size from all the spins that contributed to collecting the 99 Wilds, and this average stake is used for the duration of the triggered Free Spins round, ensuring the bonus is played at a representative bet level based on the player's activity during the collection phase.

What is the maximum win potential in the Book of 99 slot?

The Book of 99 slot game offers a substantial maximum win potential for players. According to the information provided by the developer, the highest possible payout a player can achieve in this game is 12075 times their total bet amount. This significant maximum win figure contributes to the game's classification as having high volatility. This indicates that while the frequency of wins might be lower compared to slots with reduced volatility, the potential rewards, including the capacity to hit this substantial multiplier of 12075x the stake, are considerably higher, especially when the bonus features, like the Free Spins with expanding symbols, align favourably.
