How Book of Souls Plays
Book of Souls uses a straightforward 5×3 grid with 10 fixed paylines. You set your bet, spin, and wait for matching symbols to land left-to-right on active paylines. The title track of the game is Egyptian—pyramids, scarabs, amulets, and hieroglyphic gold icons dominate the reel set. Wins pay out according to the paytable, and if no payline connects, that spin is a loss.
The slot's core mechanic revolves around the expanding symbol feature: certain symbols (typically the high-paying or thematic icons) can expand to cover an entire reel when they land, creating additional winning combinations. This mechanic is what drives the big payouts—a single expanding symbol landing on a reel during the bonus round can turn a modest free-spin sequence into a multi-hundred-times-bet result. The book symbol acts as both the scatter trigger and the key to unlocking the free-spins bonus.
Free Spins and Scatter Triggers
Land three or more book symbols anywhere on the reels to trigger free spins. Typically, three books grant 10 free spins, four grant 15, and five grant 20 (exact amounts vary slightly by operator configuration). During free spins, the expanding symbols become far more prevalent, and additional scatters can retrigger extra spins. This is where the 5000× ceiling becomes achievable: a run of three or four re-triggering scatters combined with back-to-back expanding symbols can multiply your initial free-spin win significantly.
Free spins are the make-or-break feature in Book of Souls. In a base-game session, you might spin for 50+ rounds without triggering the bonus; then, when you land that scatter cluster, the free-spin sequence has the potential to return 200–800× your triggering bet if the expanding symbols cooperate. This is the high-volatility trade-off: long dry spells punctuated by occasional explosive bonuses.
Expanding Symbols and Cascades
When an expanding symbol lands on Book of Souls, it enlarges to fill the entire reel, creating or enhancing winning combinations. This mechanic applies to several mid-to-high-paying symbols and becomes most dangerous during free spins, when expanding symbols can land back-to-back.
The game does not feature cascading reels (where winning symbols disappear and new ones fall); it's a static grid. However, the expanding mechanic effectively mimics a cascading feel—if you land two expanding symbols on the same spin, the paytable multiplication compounds, and if a retrigger scatter lands in the same spin, you're adding more free spins to your sequence. This "stack effect" is where patient players see their free-spin wins escalate from modest (50–100×) to spectacular (500–2000×).
Theme, Graphics, and Sound
Spinomenal's Egyptian aesthetic is functional and thematic without being visually cutting-edge. The golden amulets, scarabs, and hieroglyphic tiles are recognizable; the book symbol is clearly the star of the feature set. The audio is period-appropriate—temple bells and woodwind samples accompany wins, and the free-spin jingle signals the bonus round with adequate fanfare. For a 2018-era slot, the production is serviceable. It won't rival modern Pragmatic Play or NetEnt releases in visual complexity, but it's not outdated either. The theme consistency helps—Book of Souls doesn't pretend to be contemporary; it leans into the Egyptian mystique without winking at the player.
RTP, Volatility, and Bankroll Planning
Book of Souls carries a 96.07% RTP, which is above-average for a video slot. That means, theoretically, over millions of spins, the game returns $96.07 to the player for every $100 wagered. In practical terms: if you wager $100 on Book of Souls and never adjust your bet, you'd expect to get back roughly $96 by the time your $100 is exhausted. The remaining $4 is the house edge. Over a short session (10 spins, 100 spins), the RTP tells you nothing—variance dominates. Over a thousand spins, RTP becomes more meaningful.
Volatility is high, which means payouts cluster at the extremes: either you're spinning without significant wins, or you're in a bonus round with multipliers stacking. For high-volatility slots, a typical session looks like this: 30 spins with no payline hits (or small hits recovering 5–10% of your bet), followed by a free-spins trigger that either fizzles (returning 20–50× your bet) or explodes (returning 300–1000× or more). Your bankroll must accommodate this swing.
Bankroll recommendation: For comfortable play on Book of Souls at $1 per spin, bring a starting bankroll of $200–$500. This gives you roughly 200–500 spins before depleting your funds, which statistically increases the odds of hitting at least one decent bonus round. For $10 per spin, $2000–$5000 is reasonable. The higher your volatility tolerance, the smaller a bankroll you can use—but expect dry stretches and account for the possibility of hitting your loss limit before a big win shows up.
Where to Play Book of Souls in Canada
Book of Souls is widely available at iGO-licensed Ontario casinos and at offshore CA-facing operators. In Ontario, you'll find it at bet365.ca, FanDuel, and BetMGM, among others. Outside Ontario, private operators (KGC-licensed, Curaçao-licensed) carrying Spinomenal's library include Bodog and other long-standing brands. Each casino offers different welcome bonuses—check for Interac e-Transfer availability and minimum withdrawal thresholds before signing up. Deposit limits are usually $25–$1000 per transaction.
Demo Play Options
Most Spinomenal slots, including Book of Souls, are available in free-play / demo mode. You can load the game on a casino's website (in-browser or mobile app) and spin with virtual credits, no deposit required. Demo play carries the same RTP as real-money play at that casino, so it's a faithful test-drive. Use the demo to familiarize yourself with the expanding symbols, the free-spin frequency, and your emotional response to dry stretches before wagering real funds.
Tips for Playing High-Volatility Slots
High-volatility slots like Book of Souls are best approached with a fixed loss limit and a session budget. Set a maximum loss before you start—say, $100—and stop when you reach it, regardless of whether you're "due" for a win. There's no due. Each spin is independent.
When playing a high-volatility slot, resist the temptation to increase your bet size during a losing streak, hoping to recover faster. This is a fast way to deplete your bankroll. Instead, maintain a consistent bet size and play long sessions (100+ spins) to increase the statistical probability of hitting a bonus round. A high-volatility slot played for 20 spins has a good chance of showing nothing; 200 spins dramatically improves your odds of landing at least one feature-trigger.
Similar Egyptian-Themed Slots Worth Trying
If you enjoy the Egyptian theme and high-volatility mechanic of Book of Souls, consider:
- Book of Ra (Novomatic/Greentube): the original book-style game, 96% RTP, similarly high-volatility.
- Book of Dead (Play'n GO): 5-reel, 10-payline, 96.21% RTP, expanding-symbol feature, very similar structure to Book of Souls.
- Scarab Gold (Pragmatic Play): 5-reel, 25-payline, 96.48% RTP, Egyptian theme, lower volatility than Book of Souls, more frequent smaller wins.
- Temple of Aurum (Pragmatic Play): 5-reel, 40-payline, 96.25% RTP, Egyptian theme, medium-high volatility, multi-level bonus rounds.
These alternatives share Book of Souls' thematic appeal and feature-driven gameplay but vary in RTP, volatility, and payline count—test-driving a few via demo play will help you find the variant that suits your bankroll and patience level best.

Verdict: Is Book of Souls Worth Playing?
Book of Souls suits patient players with a appetite for risk and a bankroll to support long dry spells. If you enjoy Egyptian themes, free-spin mechanics, and the potential for four-to-five-digit wins (in bet multiples), this slot delivers. The 96.07% RTP is respectable, and the expanding-symbol feature is engaging during bonus rounds.
Avoid Book of Souls if you prefer frequent small wins, dislike losing streaks, or are playing on a tight budget. High-volatility slots punish short sessions and require discipline to stop at a loss limit.
For most Canadian players, Book of Souls is a solid choice among Spinomenal's library—worth a demo session before depositing real money. If the theme resonates and you can afford the variance, it's worth playing. If you prefer a smoother ride, Book of Dead or Scarab Gold offer lower-volatility alternatives.
