Book of Kingdoms

In the base game Book of Kingdoms, everything is pretty clear: five reels, three rows, 25 paylines. Most of the time, you just wait for the bonus to fall out - here it really decides. But you won't get bored: Coin Bonus symbols can appear on the reels, and if at least five coins appear on the same spin, the mini-game is activated. The process itself is simple - spin to a bonus or to a large combination with top symbols. Sometimes the game throws up long series without events, but one or two coins or a good wild can change the balance in a couple of spins.

Bonus features here are for every taste. Firstly, the classic Free Spins – three Scatter symbols (aka Book) trigger ten Free Spins, where a random Special Expanding Symbol is selected before the start begins. During the bonus, this symbol can expand to the entire reel if it appears at least two or three times per spin, and it pays regardless of the lines. The bonus can be extended if three Scatters appear again, there is no limit on the number of spins.

The second feature is Coin Bonus. If you catch five or more Coin Bonus symbols, a respin game is triggered: only coins remain on the screen, and the rest of the reels spin three times until a new coin appears. Each time a new coin appears, the counter returns for three respins. Coin Bonus has fixed jackpots: Mini, Minor, and Major, and if you're lucky, you can also catch the Major, which gives up to 1,000x the bet.

The symbols in Book of Kingdoms are fully consistent with the theme of adventure and the East: three heroes (Explorer, Sultan, Girl), a mysterious book (Book), a tiger and standard card values. The most expensive symbol is Explorer. Book plays two roles at once: Wild and Scatter, triggers the bonus and replaces all other symbols. Coin Bonus separately — to start the respin game and receive jackpots. Small winnings come from card symbols, large ones only through bonuses and top symbols with expansion. If you are lucky in the bonus with the expanding symbol, you can hook a decent x, especially with Explorer.

The maximum win in the slot is 20,000x the bet, and this is a really serious claim for such a mechanic. Theoretically, to do this, you need to catch a Major Jackpot in Coin Bonus or a full screen of the top symbol in Free Spins with an extension. In practice, bonuses often give 50x-300x, and large drifts do not happen often, but the probability of a "shot" is constantly felt. The volatility is medium-high, there are periods of calm, but one good bonus or Coin Bonus can cover a long series of small spins.

The graphics in Book of Kingdoms are nice — everything looks lively, the colours are saturated, and the symbols are easy to read even on small screens. The backdrop is a typical East-Asian-themed city, with a bazaar, domes and sunsets. The music supports the atmosphere of adventure, but does not get into your ears. There are not many animations, but they are neat: no slowdowns, the slot is well optimised for different devices.

Book of Kingdoms is perfect for those who love the classic "Book of...", but are tired of complete predictability and want a little new feeling. The coin minigame adds dynamics, and the familiar expanding symbol mechanic will keep you entertained. For beginners, the slot will be clear from the first minutes, and experienced players will like the opportunity to catch a really big win.

The RTP of Book of Kingdoms is standard - usually 96.69%, but Pragmatic Play has versions with a reduced RTP (sometimes up to 94%). I always advise you to check the indicator in each casino. Volatility is closer to high, so it is better to choose a bet according to the size of the bankroll and not count on frequent winnings - everything here is based on bonuses and patience. If you catch the Coin Bonus, the main thing is not to rush and not to chase the jackpot every spin.
