Details on the Book of 99 Slot

Book of 99 Slot Overview

A game from Relax Gaming takes players to Homer’s “Odyssey”. The time this epic was written is debated, but researchers agree it was around 700 BC. This work holds attention through its narrative. We follow Odysseus on his journeys, including his use of the Trojan horse tactic, ending the Trojan War.

This story shows Homer’s writing skill. Relax Gaming used this theme for a game in the “Book” series, presenting known functions with added elements. Play slot to experience these functions.

“Book of 99” is an online slot from Relax Gaming. It has 5 reels, 3 rows, and 10 paylines. Bets go from a low 0.10 to a high 100. A key point is its RTP (Return to Player) at 99.00%. For details on performance metrics, check the slot rating. The game shows high volatility, a win hit frequency of 29.83%, and wins can reach 12075 times the bet.

As seen in “Book” series games, expanding symbols are present. These activate during free spins when 3 or more Wild symbols land. To help achieve wins, a Collection function is included: gathering 99 Wild symbols also starts free spins. Functions available in the game include: Wild symbols, free spins, expanding symbols, and Collection.

Information on the Book of 99 Game

The game’s look matches Greek style. Background visuals show buildings from Greece’s past. Large columns frame the game area. Characters from Homer’s “Odyssey” appear on reels with sound that fits the setting. Developers made the game work on different devices. Mobile users access free spins by getting 3 or more Wild symbols.

Low-value symbols are cards 10, J, Q, K, and A, with a gem look. Landing 3 or more matching symbols on nearby reels, starting from the left, forms a win. Higher-value symbols are Odysseus, a woman with a hood, a Siren, and a Cyclops. They start at 1×1 size, but with expanding reels, a chosen symbol can grow to 1×3 and cover a full reel. The game has 10 symbols. The last one is the Wild, shown as a book. A lower number of symbols can mean win sets happen more often. Let’s look into this game’s functions.

Book of 99 Game Functions

What is the top win in the Book of 99 slot?

The top possible win is 12075 times the bet.

What functions are in the Book of 99 game?

The game includes wild symbols, free spins, expanding symbols, and the collection function.

Wild Symbols

This symbol helps make more win combinations on reels by standing for other symbols. It also serves as a scatter symbol; 3 or more landing starts free spins.

Free Spins

A main function is free spins. Getting 3 or more Wild symbols activates this, giving 10 free spins. If 3 or more Wild symbols land again during these spins, the player gets 10 more.

Expanding Symbols

Before free spins start, one paying symbol is picked at random. When this symbol lands on reels, it grows to take over the full reel. These symbols create wins even if they are not next to each other.

Collection

This function triggers free spins. It activates by collecting 3 or more scatters (already covered by Wilds). Another way to start free spins is using the “Collection”. In the base game, Wild symbols landing are collected. When 99 Wild symbols are gathered, free spins begin. The average bet over the spins used to gather 99 Wilds is used.

F.A.Q.

What is the theme of the Book of 99 slot?

The Book of 99 slot from Relax Gaming is deeply rooted in classical Greek mythology, specifically drawing inspiration from Homer's epic poem, "The Odyssey." This ancient narrative, believed to have been written around 700 BC, follows the journeys of Odysseus, including famous elements like the Trojan horse tactic used to end the Trojan War. The game's visual presentation strongly reflects this theme, featuring a setting designed in Greek style with background visuals showing ancient Greek buildings and large columns framing the game area. The symbols on the reels include characters from Homer's "Odyssey," complemented by sound effects that enhance the historical and mythological atmosphere.

Who developed the Book of 99 slot and what are its basic technical specifications?

The Book of 99 slot was developed by Relax Gaming, a known provider in the online slot market. This game is part of their popular "Book" series. Structurally, the game features a standard layout consisting of 5 reels and 3 rows, providing a familiar grid for players. It offers 10 fixed paylines for forming winning combinations. The betting range is designed to accommodate various player preferences, starting from a low minimum bet of 0.10 up to a high maximum bet of 100. These core specifications establish the foundational gameplay experience offered by the slot.

What are the main performance metrics of the Book of 99 slot, such as RTP and volatility?

The Book of 99 slot is notable for its impressive performance metrics. It boasts a very high Return to Player (RTP) rate of 99.00%, which is significantly above average for online slots, suggesting a high potential for player return over time. The game is categorized as having high volatility, meaning wins may occur less frequently but have the potential to be larger when they do land. The text also mentions a win hit frequency of 29.83%, indicating how often a winning combination is expected to land on average. The maximum possible win in this slot is quite substantial, reaching up to 12075 times the player's bet.

What special gameplay features are included in the Book of 99 slot?

The Book of 99 slot incorporates several key special features designed to enhance gameplay and winning potential. These features are standard to the "Book" series but include unique elements. The game includes Wild symbols, which are central to triggering other features and substituting for other symbols. There is a Free Spins bonus round, initiated by landing a certain number of Wilds. During free spins, an Expanding Symbols feature is active, where a randomly chosen symbol can grow to cover entire reels. Uniquely, the game also includes a Collection function, providing an alternative method to trigger the Free Spins round by accumulating Wild symbols over time in the base game.

How can players trigger the Free Spins feature in Book of 99?

The Free Spins feature in the Book of 99 slot can be triggered in two primary ways, offering players multiple paths to this potentially lucrative bonus round. The first and more traditional method for "Book" style slots is by landing 3 or more Wild symbols anywhere on the reels during the base game; achieving this awards the player 10 free spins. If 3 or more Wild symbols land again during the free spins, an additional 10 spins are awarded. The second method is through the unique Collection function, where collecting a total of 99 Wild symbols in the base game automatically triggers the free spins feature, using the average bet size from the spins used to gather the 99 Wilds.

Describe the Expanding Symbols feature in Book of 99.

The Expanding Symbols feature in Book of 99 is a core mechanic of the Free Spins bonus round, significantly impacting winning potential. Before the Free Spins begin, one of the standard paying symbols is randomly selected to become the special expanding symbol for the duration of the feature. Whenever this chosen symbol lands on the reels during the free spins and forms part of a potential win, it expands to cover the entire reel it landed on. A key advantage of these expanding symbols is that they pay scatter-style; they do not need to land on adjacent reels or follow the established paylines to create a win, only needing to appear on a sufficient number of reels anywhere on the grid.
