Book of Kingdoms is the second book-style slot from Pragmatic Play (Reel Kingdom), spinning out across 5 reels, 3 rows with 25 paylines. Beyond the classic expanding symbol bonus round, this slot introduces an exciting Hold & Win Jackpot Respins feature that adds a fresh dimension to familiar gameplay.
Book of Kingdoms is Pragmatic Play (Reel Kingdom)'s second entry in the book slot genre, and it delivers on a 5-reel, 3-row setup with 25 ways to win. Alongside the traditional expanding symbol bonus round, players can also unlock a thrilling Hold & Win Jackpot Respins feature that sets this game apart from its predecessor.
The slot carries medium-to-high volatility, and non-jackpot wins of up to 500x your stake are achievable. Unlike its sister title, Return of the Dead — which offered little innovation beyond a slightly elevated payout rate — Book of Kingdoms at least makes a genuine effort to distinguish itself from the crowded book slot market.
The Respins Jackpot mechanic brings meaningful balance to the overall gameplay experience, and the chance to land fixed jackpots worth up to 1,000x your bet injects a welcome dose of extra excitement into each session. The toned-down volatility may appeal to casual, lower-risk players, but it does come at the cost of reduced win potential compared to higher-variance alternatives.
The slot's hatless, grinning adventurer protagonist lacks the magnetic screen presence of iconic slot characters like John Hunter — and if Pragmatic Play plans to build a longer series around this oddball explorer, a signature hat would certainly help establish his identity.
The hatless, ever-smiling explorer makes his return — though eagle-eyed players will spot him sporting a stylish Indiana Jones-inspired fedora within the paytable artwork. It seems Pragmatic Play (Reel Kingdom) has plans to develop a full series around this quirky adventurer, following what many assumed was a standalone appearance in Return of the Dead.
After an extended series of teasers, our review team managed to trigger the bonus round at 0:54 in the 200 spins highlights video available below — giving players a real taste of what the free spins feature has to offer.
Book of Kingdoms runs at a lower volatility level than its sister game Return of the Dead, and unlike that title, it doesn't simply clone the book slot formula without adding anything new. The slot does incorporate a standard "book-style" bonus round, but the added Hold & Win Respins Jackpot feature gives it more personality and replay value.
This makes Book of Kingdoms a more justifiable release than its predecessor, though seasoned players shouldn't expect any groundbreaking innovations. The symbol values have been noticeably reduced, and the maximum win potential sits at 500x your stake — a significant step down from the 5,000x ceiling seen in comparable titles.
The main character — a grinning, hatless wanderer — still reads as an oddball, but he's now joined by a cast of companions including a wizard, a woman, and a monkey, adding some visual variety to the reels. Overall, Book of Kingdoms is a solid, if unspectacular, entry in the book slot category that offers reliable entertainment for players who enjoy this genre.
