Book of Kingdoms
Book of Kingdoms Introduction
Following the success of Return of the Dead, Reel Kingdom and Pragmatic Play returned to the increasingly crowded “Book” genre with Book of Kingdoms. Rather than simply copying the familiar Book of Ra formula, the developers introduced a Hold & Win-style Money Respin feature alongside the traditional expanding-symbol Free Spins round.
The result is a slot that attempts to combine two popular mechanics into a single package. On one hand, players have the classic Book feature that has made the genre so successful for decades. On the other, they have jackpot coins and respins capable of producing substantial rewards outside the bonus round.
Set in a mystical Middle Eastern kingdom filled with sultans, monkeys, treasures and ancient secrets, Book of Kingdoms offers a more feature-rich take on the traditional book slot formula. With an RTP of 96.69%, medium volatility and a maximum win of 20,000x the player’s stake, it also offers considerably more upside than many competing titles in the genre.
Overview of Book of Kingdoms
Book of Kingdoms is played on a classic 5-reel, 3-row layout with 25 fixed paylines. At first glance, the game looks exactly like the sort of book slot players have seen countless times before.
However, Reel Kingdom has added several twists to distinguish it from its competitors.
The game’s central symbol is the Book of Kingdoms itself, which acts as both Wild and Scatter. Landing three or more books triggers the Free Spins feature, where a randomly selected expanding symbol can create huge wins. Alongside this traditional mechanic sits the Money Respin feature, where silver coin symbols can trigger jackpot opportunities and instant cash prizes.
This combination of old and new mechanics gives the game a broader appeal than many standard book slots.
Book of Kingdoms RTP, Payout, and Volatility
Book of Kingdoms is available with a maximum RTP of 96.69%, although lower RTP versions may exist depending on the casino offering the game. Players should always verify the RTP version before playing.
The game is generally classified as medium volatility. This makes it noticeably less aggressive than many modern book slots, allowing players to experience more regular payouts while still retaining the potential for significant wins.
The headline figure is the maximum win potential of 20,000x the player’s stake. This places Book of Kingdoms comfortably above many traditional book slots and gives players a genuine reason to chase both the Free Spins and Money Respin features.
For a medium-volatility release, the win ceiling is particularly impressive.
Book of Kingdoms Graphics and Gaming Experience
Visually, Book of Kingdoms follows a familiar path. The setting resembles a magical Arabian kingdom filled with sultans, exotic treasures, monkeys, snake charmers and hidden riches. While the theme is hardly revolutionary, it provides a colourful backdrop for the action and differentiates the game from the Egyptian settings commonly associated with book slots.
The artwork is polished and professional, although not particularly groundbreaking by modern standards. Character symbols are well designed, and the book symbol itself stands out nicely whenever it lands on the reels.
Animations are relatively modest, with most of the visual excitement occurring during the Money Respin feature and Free Spins round. The soundtrack adopts a suitably mystical tone and complements the setting without becoming repetitive. The game also performs smoothly across desktop and mobile devices.

Book of Kingdoms Bonus Features
The Book of Kingdoms symbol acts as both a Wild and Scatter throughout the game.
Landing three or more Book symbols awards five Free Spins. Before the feature begins, one regular paying symbol is selected at random as the special expanding symbol. Whenever this symbol appears during Free Spins, it expands to cover the entire reel and can create substantial payouts across multiple paylines.
The game’s most distinctive addition is the Money Respin feature. Silver Coin symbols can land carrying cash values or jackpot awards. When enough qualifying symbols appear, the Money Respin feature activates, locking the coins in place while awarding additional respins in an attempt to fill more positions. Cash values are collected at the end of the feature, while jackpot symbols can award one of several fixed jackpot prizes.
The Mega Jackpot can award up to 1,000x stake, adding another route to significant wins outside the traditional Free Spins feature.
Book of Kingdoms Features
What separates Book of Kingdoms from countless other book slots is its willingness to blend genres.
Most book slots rely entirely on expanding symbols and Free Spins. Here, Reel Kingdom adds an additional layer of excitement through the Money Respin feature and jackpot prizes.
The two mechanics complement each other well. Players chasing the traditional expanding-symbol feature still have plenty to enjoy, while the Money Respin feature ensures there is always the possibility of a meaningful payout during the base game.
The medium volatility profile also helps make the game more accessible than some of the genre’s more extreme entries.
Overall, Book of Kingdoms feels like an attempt to modernise the classic book slot formula without abandoning the elements that made it popular in the first place.
