Book of Ra's RTP can be set anywhere from 88% to 97% by the operator — one of the widest configurable ranges of any pokie you'll find at Zoome. That's a meaningful spread: at the low end, the house edge is more than double what it is at the high end. Most reviews of this pokie skip that detail entirely and just quote the headline RTP figure, which isn't necessarily what's actually running on the reels.
A classic that's still worth understanding
Book of Ra is Novomatic's Egyptian-themed pokie, first released in 2005 with a Deluxe version following in 2012. It's a standard 5-reel, 9–10 payline game — no cluster pays, no Megaways, just the classic format that most modern high-volatility pokies have moved away from. Min bet at Zoome is A$0.01, max is A$50, and the max win is 5,000x on the Deluxe version (25,000 coins on the original).
The core mechanic is Free Spins — 10 rounds triggered by scatters — combined with an expanding random symbol during the bonus. When that symbol lands, it fills the entire reel it appears on, which is where the bulk of any meaningful win comes from. There's also a Gamble feature: double or nothing on any win, a genuine coin-flip with no house edge adjustment built in beyond the base game RTP.
| Parameter | Value | Notes |
|---|---|---|
| RTP | 92.13% (original) / 95.1% (Deluxe) | Operator-adjustable 88%–97% |
| Volatility | High | Long dry spells between features |
| Max win | 5,000x (Deluxe) | 25,000 coins on the original version |
| Min / max bet | A$0.01 / A$50 | 9–10 adjustable paylines |
| Bonus Buy | Not available | Free Spins must be earned through base play |
| Key feature | Expanding symbol | Fills the entire reel during Free Spins |
| Demo mode | Available | Good for learning the paytable before real punts |
Author's tip from Isabella Valli, Head of iGaming Compliance & User Safety: "Check whether Zoome is running the original Book of Ra or the Deluxe version before you play — they look nearly identical but sit at different RTP baselines, and the paytable screen will confirm which one has loaded."
Original vs Deluxe — which is actually running at Zoome
Book of Ra and Book of Ra Deluxe share the same theme and core mechanic but differ in RTP and payline structure — the original sits around 92.13%, the Deluxe closer to 95.1%. Because Novomatic allows operators to configure RTP within an 88%–97% band regardless of which version is loaded, the safest approach is to check the in-game paytable directly rather than assume either figure applies at Zoome.
I noticed the two versions are visually close enough that players often don't realise which one they're on. If session outcomes feel meaningfully different from what you'd expect at 95%+ RTP, it's worth checking the paytable screen before assuming it's just a bad run.
How Book of Ra compares to modern high-RTP pokies
At its top setting, Book of Ra's 97% RTP is competitive with anything else in the Zoome library. At its bottom setting, 88% puts it well below the modern pokie average of roughly 96%. The gap matters because Book of Ra doesn't have a Bonus Buy option — you can't pay to skip into Free Spins, so the base game's RTP setting directly shapes how many spins you'll need before the expanding symbol shows up.
- Confirm which version — original or Deluxe — is loaded before you set a session bankroll.
- Check the paytable for the RTP setting in use; the configurable range here is wider than most modern releases.
- Expect long stretches between Free Spins triggers — high volatility with no Bonus Buy means grinding is the only path to the feature.
The Gamble feature — a genuine coin flip, not a strategy
After any winning spin, Book of Ra offers a Gamble feature: double your win or lose it, typically by picking the colour of a hidden card. It's worth understanding this for what it is — a roughly even-odds side bet layered on top of the base game's RTP, not a way to improve your overall expected return. Some players use it to chase specific bankroll targets after small wins; others skip it entirely to lock in whatever the base game paid out. Neither approach changes the underlying maths, so it comes down to personal risk tolerance rather than strategy.
Where I'd be cautious is using Gamble repeatedly on the same win — each attempt is an independent coin flip, and the odds of doubling five times in a row are exactly what you'd expect from flipping a coin five times: long odds that compound quickly against you.
Why the expanding symbol matters more than paylines
With only 9–10 paylines, Book of Ra's base game math leans heavily on the expanding symbol feature during Free Spins rather than on payline density the way some modern pokies do. When that symbol lands and fills a full reel, it can turn what would otherwise be a modest win into a substantial one — this is effectively where most of the game's variance lives. Outside of Free Spins, wins tend to be smaller and more frequent along the standard paylines, which is part of why the overall experience feels streaky: modest base-game returns punctuated by occasional large swings once the bonus triggers.
This is a genuine classic with real nostalgia value, but the wide RTP range means it pays to check before you commit a session. As with any pokie, this is an 18+ real-money product — set your limits before you start spinning.
