Step into a world where history is written in letters of gold, and where a single spin can turn an ordinary adventurer into a wealthy winner. Book of Kingdoms from Pragmatic Play isnβt just another slot with βBookβ in the title β itβs an exotic adventure that pulls you into a realm of mystery, desert sands, magic and endless possibilities. Here, youβll set off on a journey to an oriental kingdom ruled by sorcerers, adventurers and mystical beings. The game features 5 reels, 3 rows and 25 paylines, offering a solid mix of simplicity and plenty of room for exciting wins.
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
A slot with medium volatility. Wins occur occasionally and are balanced. The game has an alternating course without extreme fluctuations, suitable for players looking for a compromise between risk and winning potential. More about volatility here.
Slot theme and symbols
From the very first spin, youβre welcomed by a story that feels like a cinematic adventure theme β sand swirls in the air, the sun sets behind the palms, and youβre standing in the middle of an ancient city where, to the beat of drums and whistles, Book of Kingdoms lies hidden. A book that can bring you not only glory, but also incredible riches thanks to its oriental theme. So pop on your turban, dust off the treasure map, and letβs see what this game has tucked away between the pages of its golden leaves. Alongside classic card symbols (J, Q, K, A), youβll find monkeys, ladies, sultans and adventurers. Land three or more book symbols to trigger 5 Free Spins. Before they begin, a special expanding symbol is chosen at random, with the power to expand across an entire reel and pay out wins regardless of position. Youβll also have MONEY symbols available, which can trigger a MONEY Respin.
Theme and symbols Book of Kingdoms
And if thatβs not enough, you can also look forward to MEGA, MINOR and MAJOR Jackpots. The game has an RTP of 96.69%, which is a very solid figure, and the volatility is medium-high, so youβll see smaller, more frequent wins mixed with the chance of bigger hits in the bonus rounds. Pragmatic Play has gone for a very player-friendly approach β the game is easy to understand, has a clear interface, and plays brilliantly on both desktop and mobile.

Money symbol
Do you spot a silver symbol on the grid? If so, each spin gains a value from a predefined set or takes on the values MINOR, MAJOR and MEGA. Once 5 or more Money symbols land, the MONEY Respin feature is triggered. The prizes are as follows:
MEGA Jackpot β 1000x total bet
MAJOR Jackpot β 100x total bet
MINOR Jackpot β 30x total bet
MONEY Respin
Once the wins are paid, the feature begins. The regular symbols disappear and only those that triggered the feature remain. The standard reels are then replaced with special reels containing symbols and empty spaces. You start with 3 bonus respins. Any symbols that land during the feature stay locked in place until it ends. If another Money symbol lands, the number of bonus respins resets back to 3. This can go on for quite a while β if luckβs on your side.
WILD Symbol
In Book of Kingdoms, youβll find WILD symbols that look like books written in an ancient language. They can substitute for all regular symbols except the BONUS symbol and the Money symbol.
The book symbol can even act as the BONUS symbol. Itβs a real chameleon among the symbols. Land 3 of these and youβll trigger Free Spins! On top of that, it also pays as part of winning combinations. Before the Free Spins begin, youβll receive 5 Free Spins and a special expanding symbol will be randomly selected from all symbols except the BONUS and Money symbols. During Free Spins, after wins are paid, symbols expand vertically to cover all 3 positions on the reel. However, expansion only triggers when there are enough symbols present to form a win. If you manage to land 3 or more WILD symbols during Free Spins, youβll be awarded an extra 5 Free Spins with the currently selected special symbol.
