Why each fits
Players come to Book of Vikings for a specific combination: high volatility on a clean 5x3 grid, a 96.50% RTP, Free Spins built around an expanding symbol, and a 5,500x max-win ceiling that justifies the long base-game waits. When a session ends early, the shortcut to finding games like Book of Vikings is to map those four dimensions rather than picking another Viking-skinned title. The eight alternatives below were chosen because each overlaps with Book of Vikings on at least two verified specs: same provider, matching volatility band, a comparable payline structure, or a similar max-win range.
The closest matches are other Pragmatic Play titles that share either the 5x3 ten-payline grid or the exact RTP figure. Book of theme alternatives from BGaming cover the theme-family dimension at a high volatility intensity but at a lower return rate. Understanding where each title overlaps, and where it breaks from the Book of Vikings pattern, is the clearest way to choose the right next game.
Book of Kingdoms shares the same Pragmatic Play studio and the same 5x3 Book of family format as Book of Vikings, making the structural bones immediately familiar. Its RTP of 96.69% sits close to Book of Vikings' 96.50%, and its 25-payline layout offers more active win-lines per spin than the 10-payline grid, which raises base-game hit frequency without changing the high-stakes bonus dynamic.
Where Book of Kingdoms diverges is in its bonus mechanic and volatility. The core feature is a Money Respin triggered by Silver Coin symbols, replacing the expanding symbol Free Spins that drive Book of Vikings' ceiling. Volatility is rated medium, leaning towards high, rather than the full high rating of Book of Vikings, which means Book of Kingdoms delivers a more moderate session rhythm for players who find the high-volatility dry spells of Book of Vikings too demanding.
Big Bass Floats My Boat shares the same 5x3 grid and 10-payline structure as Book of Vikings, both built on the Pragmatic Play engine, meaning the base-game rhythm and bet-per-payline feel closely matched. High volatility and an RTP of 96.07% produce a session profile similar in character: stretches of base-game play without significant returns, followed by bonus-triggered swings. Its max win of 5,000x sits slightly below Book of Vikings' 5,500x ceiling, keeping it in the same territory for big-win potential.
The separation is in theme and bonus type. Where Book of Vikings centres its Free Spins on an expanding symbol within a Norse setting, Big Bass Floats My Boat uses a fishing-themed bonus mechanic on the same Pragmatic Play chassis. Players who want the 5x3 high-volatility ten-payline engine of Book of Vikings but prefer a different aesthetic will find the structural feel here essentially the same.
Big Bass Secrets of the Golden Lake shares its core structural specs with Book of Vikings: the Pragmatic Play engine, a 5x3 grid with 10 paylines, identical high volatility, and an RTP of 96.07%. Against Book of Vikings, those shared specs make the session feel comparable in terms of hit frequency and bonus intensity, even though the two games come from different theme families entirely.
The max-win ceiling here stands at 5,000x, slightly below Book of Vikings' 5,500x, meaning the absolute upside is marginally lower. Like Book of Vikings, it operates without a bonus-buy gate, so the feature round is earned through base-game scatter collection rather than optional spending. Players looking for the same Pragmatic Play high-volatility 10-payline chassis as Book of Vikings will find this title a close mechanical parallel.
5 Lions Megaways carries an exact 96.50% RTP, matching Book of Vikings figure for figure, and both titles come from Pragmatic Play with a high volatility rating. Where the games part ways is reel architecture: 5 Lions Megaways runs a six-reel Megaways engine, meaning the number of ways to win changes dynamically from spin to spin rather than fixing at 10 paylines, and the bonus round features multiplier wilds reaching up to 40x rather than a single expanding symbol driving the ceiling.
For Book of Vikings players who want the same RTP and Pragmatic Play high-volatility engine but are drawn to a variable-reel mechanic with stacking multipliers, 5 Lions Megaways is the closest cross-format option in this set. The Asian theme and lion iconography are a substantial aesthetic departure from the Norse setting of Book of Vikings, so this is a mechanics-first recommendation rather than a thematic one.
Book of Kemet sits in the same Book of theme family as Book of Vikings and carries a volatility score of 5, placing it at the higher end of the volatility range in this comparison set. It is published by BGaming rather than Pragmatic Play, and its RTP of 95% is lower than Book of Vikings' 96.50%, a difference that compounds over longer sessions and is worth factoring into bankroll planning.
The bonus feature in Book of Kemet is accessed via bonus buy rather than landed Free Spins scatters, which is a meaningful structural change for players who prefer earning the feature through base-game play, as in Book of Vikings. The Egyptian theme replaces the Norse setting, but the intended player, someone comfortable with high-volatility session swings in a Book of framework, is the same audience Book of Vikings targets.
5 Lions carries exactly the same 96.5% RTP as Book of Vikings, both on the Pragmatic Play platform and both rated high volatility, giving the two games an identical return-rate and risk profile at the headline level. The divergence is in how wins are formed: this title uses cluster pays on a 5x3 grid, which replaces the payline concept entirely with grouped symbol adjacency, a fundamentally different win mechanic compared to Book of Vikings' 10-payline structure and expanding symbol Free Spins.
The max-win ceiling stands at 3,520x, below Book of Vikings' 5,500x, so players chasing the upper end of the win range should factor in that ceiling gap. For those who want the Pragmatic Play high-volatility engine and the same RTP as Book of Vikings but are open to a cluster-pays format and an Asian rather than Norse setting, 5 Lions is the clearest RTP-matched alternative in this set.
Book of Cats occupies the same Book of theme family as Book of Vikings and reaches a volatility score of 5, the joint-highest in this set, matching the high-volatility appetite that Book of Vikings demands. It is produced by BGaming rather than Pragmatic Play, which affects the grid feel and symbol landing frequency.
The RTP for Book of Cats stands at 94%, notably lower than Book of Vikings' 96.50%, a factor that matters across any meaningful number of sessions. The bonus buy mechanic offers a shortcut to the feature round rather than requiring landed scatters, which changes the base-game dynamic for players who prefer the Book of Vikings model of working toward the feature organically. Players who weight the Book of theme family and maximum volatility intensity above RTP matching will find this title closest on those two axes.
Book of Crown carries an RTP of 96.05%, close to Book of Vikings' 96.50%, and sits in the same Book of theme family. Published by PoggiPlay, it operates on a five-reel layout, giving it a similar visual footprint to Book of Vikings. The key separation is volatility: Book of Crown is rated 3, placing it firmly in the medium range rather than the high band that defines Book of Vikings' session character.
For players who find the variance of Book of Vikings too demanding, Book of Crown offers a similar RTP within the same theme family but with more frequent, smaller returns and less severe base-game dry spells. The bonus buy mechanic also differs structurally from the scatter-triggered Free Spins of Book of Vikings, making the path to the feature round an optional spending choice rather than base-game play. This is the entry on this list best suited to Book of Vikings fans who want to step down in volatility without leaving the theme family.
Three structural axes separate the closer matches from the looser ones across slots like Book of Vikings: the payline model, the volatility band, and the max-win ceiling. Book of Vikings fixes 10 paylines on a 5x3 grid, so the nearest mechanical cousins are titles sharing that layout: Book of Kingdoms, Big Bass Floats My Boat, and Big Bass Secrets of the Golden Lake. All three run on the Pragmatic Play engine and carry high or near-high volatility.
The BGaming entries (Book of Cats and Book of Kemet) share the Book of theme family and high volatility intensity but carry lower RTP figures and a bonus-buy gate that changes how the feature is accessed. The two 5 Lions titles match Book of Vikings precisely on RTP at 96.50% and share the Pragmatic Play engine, but their mechanics diverge: cluster pays in 5 Lions and the variable-reel Megaways engine in 5 Lions Megaways sit at a different structural distance from Book of Vikings' fixed-payline, expanding-symbol format.
Every entry on this list was benchmarked against a casino game like Book of Vikings on four verified specs drawn from our fact store: RTP, volatility, the core mechanic, and the max-win ceiling. A title qualifies if it matches Book of Vikings on at least two of those dimensions and the match is genuine rather than surface-level.
A Book of title that switches to medium volatility or carries a notably lower RTP is a different product regardless of its name or skin. All figures are sourced from provider official game information or verified third-party audits, referenced by date in each entry. No RTP, max-win, or volatility figure in these reviews appears unless it has been confirmed in our fact store.

For players choosing between games like Book of Vikings, the decision comes down to what you are willing to trade. If the closest structural replica matters most, Book of Kingdoms gives you the Pragmatic Play engine and the Book of brand family, though at medium rather than high volatility, and with a Money Respin mechanic in place of the expanding symbol Free Spins. If the 5x3 ten-payline layout matters more than the Book of theme, Big Bass Floats My Boat and Big Bass Secrets of the Golden Lake match that grid architecture and the high-volatility profile, with a max-win ceiling of 5,000x against Book of Vikings' 5,500x.
For players who prioritize RTP above all else, 5 Lions and 5 Lions Megaways both hit the same 96.50% mark as Book of Vikings, though each uses a mechanic that differs from the fixed-payline expanding-symbol format. The BGaming entries suit players who want the Book of theme family at maximum volatility intensity and are comfortable with a lower return rate in exchange for the bonus-buy route to the feature round.
Online slots are games of chance. Every spin is decided by a random number generator, and no system, staking pattern, or "hot" machine changes the odds in your favour. There is no skill or strategy that guarantees a win, and no way to make a game due to pay out. Slots are a form of entertainment, and the cost of that entertainment is the money you stake. Treat them as something you spend on for fun, not as a way to make money or to recover money you have already lost.
Decide what you can comfortably afford to lose before you play, and set that as a firm budget. Licensed operators give you tools to hold yourself to it: deposit limits, loss limits, time-outs, reality-check reminders, and self-exclusion. Turn these on at the start rather than in the heat of a session, when a limit is far easier to set than to respect. Playing within a fixed budget, with limits already in place, is the single most reliable way to keep slots enjoyable.
Watch for the signs that it has stopped being fun: chasing losses to win money back, playing longer or more often than you intended, betting money you cannot spare, or feeling anxious, secretive, or low about how much you are playing. If any of that sounds familiar, take a break and reach out. Free, confidential help and advice are available through GamCare and BeGambleAware, whose support is independent of any operator and available whether you gamble a little or a lot. Asking for help early is a sign of good judgement, not failure. This site and its content are strictly for adults aged 18 and over.
