Book of Kingdoms: Slot Overview

Pragmatic Play partner Reel Kingdom didn’t waste much time after their previous ‘book of’ release, delivering yet another entry in the same vein. The last one, Return of the Dead, was a by-the-numbers take on the formula—solid enough, but not exactly packed with fresh ideas. Book of Kingdoms takes a slightly different route. At least, it feels different compared to the last title. Feature-wise, though, you won’t find anything that hasn’t already appeared countless times. It’s difficult to get overly excited when a game looks so familiar from the start. Still, it might surprise us—let’s see.

One obvious change is the setting—we’re not in Egypt this time. Around the 5-reel, 25-payline playfield, there are no pyramids, pharaohs, or tombs in sight. We’re still in the region, however, judging by the sultan, the fez-wearing monkeys, and the belly dancers charming snakes. An Ottoman-flavoured soundtrack winds along in the background, boosting the exotic feel and matching the unusual look nicely.

You can play on any device and choose from a very broad betting range. At the lower end, stakes start at 25 p/c, while high rollers can go up to $/€250 per spin. In terms of maths, Book of Kingdom isn’t built as one of those ultra-volatile grinders that chew through spins hunting for huge full-screen expanded symbol hits. Instead, Reel Kingdom opts for medium (3/5) volatility, while also reducing symbol values, which changes the overall feel. The default RTP is notably strong at 96.69%, though it’s worth confirming the exact version you’re on since Pragmatic Play uses flexible RTP.

The familiar man without the hat is back, shining above the reels as the highest-paying premium symbol. Behind him come the sultan, the snake lady, and the monkey, in that order. Premium line wins pay 8-20x the stake, so the best possible full-screen result tops out at 500x—well below what many higher-paying book slots can deliver. The remaining symbols are 10-A card royals. Every symbol needs at least three of a kind to pay, across the game’s 25 fixed paylines.

Book of Kingdoms: Slot Features

Alongside the expected set of free spins, players also get a surprise Money Respins feature. The key symbols to watch for are the book, naturally, and the silver shield money symbol.

The book acts as a substitute for any paying symbol to complete winning combinations—landing 3 or more also triggers 5 free spins. Before the feature starts, one pay symbol is randomly selected as the special expanding symbol. Once wins have been paid, if three or more special symbols are visible, they expand to fill every position on their reel, followed by another win check. Expanded symbols pay from any position. Scatters stay active during the round too, so three or more appearing award an extra five free spins with no limit.

After that, money symbols can land anywhere, showing either a cash value or a jackpot. If five money symbols appear, the Money Respin Bonus feature is triggered. At that point, the standard symbols disappear, leaving only the triggering money symbols in place and granting 3 respins. Any new money symbols that land during a respin lock in and reset the respins back to three. The feature ends when the grid is filled or the respins run out. In addition to cash values, money symbols can show the Minor, Major, or Mega jackpot adding 30x, 100x, or 1,000x the total bet to the payout.

Book of Kingdoms: Slot Verdict

Book of Kingdoms is a tricky one to pin down. It’s clearly a book slot in the broad sense, but there are enough adjustments to steer it away from the usual path. Whether that works will depend on how much you prefer your classic ‘Ra’ style play, and whether you see Book of Kingdoms as inconsistent or simply offbeat.

Even with the various tweaks, parts of it still feel like minimal-effort design. If Book of Kingdoms had arrived as a standalone release, it might be easier to overlook. But coming straight after Return of the Dead, it gives off a slightly shameless impression. That game was a capable, standard book slot; this one feels more like a mix of dated, low-impact, overused mechanics. It’s as though Reel Kingdom tried to appeal to everyone, but ended up diluting Book of Kingdoms so much that it may struggle to thrill anyone. It’s sort of a book slot, but without the high values that usually make expanding symbols so appealing. It’s sort of a jackpot slot too, yet the top prize is a relatively modest 1,000x per spin.

Free spins are usually the core of most book games, and the version in Book of Kingdoms may be among the stingiest around. For starters, you only get five spins; then, symbol values are low, meaning the dream of landing 5,000x on a spin is cut down to 500x at best. On top of that, premium symbols require at least three of a kind, so you don’t even get the small consolation of expanding two-symbol wins.

At first glance, non-jackpot payouts look tempting. The paytable lists a win cap of 20,000x, but it feels more theoretical than realistic. Mathematically, you’d be looking at 40 full-screen premium hits during a bonus round. That’s not impossible, but it’s difficult to imagine it happening without a genie granting a favour.

Ultimately, there are stronger choices if you want a book slot, and better options if you’re chasing jackpots. Book of Kingdoms doesn’t truly stand out in any single area, leaving this mix-and-match set of features feeling like less than the sum of its parts.
