Book of Ra vs Book of Ra Deluxe: what has changed and which version to choose?
Introduction: why compare two versions of the same slot?
If you ever spun the reels in Book of Ra, you probably noticed that in the catalogs of casinos, the original is marked with Deluxe. At first glance — the same ancient Egyptian theme, the same explorer with a notebook, the same Book. But behind the external similarity lies a series of technical and visual changes that directly affect the gaming process and the payout mathematics.
In this article, we will break down both versions in detail: from the number of lines to the presentation of the bonus symbol, so you can consciously choose which one to prefer: 'Book of Ra' or 'Book of Ra Deluxe'.

Graphics and sound: the first thing that catches the eye
Book of Ra Classic (2005)
The original was created in an era when slots were launched through Flash plugins and were called terminals. The symbols are drawn with simple 2D-sprites with a limited palette. The animations are minimal: symbols appear, the winning line is highlighted with a static frame. Sound accompaniment is characterized by a 'arcade' loop with a coin effect during payout.
Book of Ra Deluxe (2008)
Deluxe version received revised symbols: the contours became clearer, the shades more subdued, the palette warmer. The font Barabansky has a refined gradient and a light texture of papyrus. The animation of the win is complemented by bursts, and the sound row is a denser stereo-mix with an accent on 'cinematographic' soundtrack upon activation of the freespins.
The difference in graphics does not affect the mathematics, but makes the lengthy sessions in Deluxe visually more soothing, especially on smartphone and tablet screens.
Payout lines: 9 against 10
This, please, is the main structural difference.
- Classic offers 9 fixed lines (classic Novomatic scheme).
- Deluxe adds a tenth line, passing through the central row.
What does this give in practice:
- The probability of forming a winning combination on one spin increases approximately by 10–11% with other equal conditions.
- The minimum bet per spin increases from 0.09€ to 0.10€ — the difference is symbolic, but it exists.
- In the bonus round, the tenth line is also active, which increases the chance of repeated winnings due to the expanding symbol.
RTP and volatility: the mathematics is almost identical
All versions operate on the same random number generator (RNG) Novomatic, and the declared RTP holds in the corridor of 95.10 – 96.00% depending on the operator's configuration. In classic editions, the figure is often 95.10%, in Deluxe — 95.10–96.00%, while the upper limit is encountered in updated HTML5 builds 2018+.
Volatility in both cases is medium-high. This means:
- The frequency of winning spins is moderate (for example, every 3–4th spin brings some payout).
- The main payout potential is concentrated in the bonus round with the expanding symbol.
- Dispersion within the session is felt: possible series of 15–20 'empty' returns in a row.
The difference in RTP between versions minimal and should not be a key factor in the choice. It is much more important to check the specific percentage set by the operator, in the section 'Game Rules' or 'Info'.
Bonus function: mechanics are the same, nuances are different
General scheme (all versions)
- Three or more symbols of the Book of Ra in any position activate 10 freespins.
- Before the start of the round, a random symbol is selected from the special expanding symbol (any from the payout table).
- When this symbol appears on the baraban, it expands across the entire reel, forming a payout on all active lines, even if adjacent positions are empty.
- Three Books in the time of frispins retrigger another 10 spins.
Differences in Deluxe
- Thanks to the tenth line, the expanding symbol covers a little more combinations, which statistically gives +3–5% to the average payout in the bonus.
- In some Deluxe editions, a microanimation of the expanding symbol selection is added (the book 'is expanded'), which does not affect the RNG, but enhances the immersion.
- In the HTML5 version of Deluxe frispins, you can restart the ungranted number of times, just like in the early Flash builds Classic encountered a program limit of 200 frispins (in practice, almost unattainable).
Gamble function (both versions)
After any win, the player can double the sum by guessing the color of the hidden card. The mechanics are identical in both versions: 50/50, series up to five doubled wins.
Gameplay and 'features' of the game
| Aspect | Classic | Deluxe |
|---|---|---|
| Return speed | A bit slow (old engine) | Faster, optimized for mobile |
| Autospin | Up to 100 cycles | Up to 100 cycles + 'Fast spin' mode |
| Bet interface | Buttons '+/–' by lines | Common rate bonus, selection of line numbers |
| Payout table | Static, in a separate window | Pop-up, with animation symbols |
| Mobile game | Only through a browser emulator | Native HTML5 version (portrait and landscape) |
For a player accustomed to modern slots, Deluxe feels more 'responsive': the spin speed is higher, the interface is adapted for touch screens, and the loading of the round takes a long time.
Which version suits whom?
- Book of Ra Classic — for nostalgic players and those who prefer a minimalist visual without unnecessary animations. Nine lines and a slightly 'raw' payout return the atmosphere of slots from the 2000s.
- Book of Ra Deluxe — for the majority of modern players. The tenth line, updated graphics, a full mobile version, and a slightly adjusted RTP make it objectively more convenient and flexible.
From a mathematical point of view, the difference between versions is negligible. The choice comes down to personal preferences in the interface and visual style.
Summary comparison: key differences in one list
- Lines: 9 (Classic) → 10 (Deluxe).
- Graphics: basic 2D sprites → HD remake with animations.
- Sound: simple stereo-loop → enriched cinematic soundtrack.
- Mobile compatibility: limited → full support for touch screens.
- Upper RTP limit: 95.10% → up to 96.00% in new builds.
- Bonus round: mechanics are identical, but the tenth line gives micro-advantages in the payout.
- Speed and UX: Classic is slow, Deluxe is optimized for fast sessions.
Frequently Asked Questions (FAQ)
Can I play both Book of Ra Classic and Deluxe simultaneously in one casino?
- Yes, most operators working with Novomatic/Greentube software offer both versions in their catalog. They do not duplicate each other, but exist in parallel.
Is the maximum payout different in the two versions?
- No. In both slots, the maximum multiplier is considered to be × 5,000 of the bet per line, which at the maximum bet gives €45,000 (Classic) or €50,000 (Deluxe) for one spin.
Does the tenth line in Deluxe affect the frequency of bonus drops?
- No. The scatter symbol (Book of Ra) is counted in any position on the reels, not on a specific line. The probability of activating the free spins is the same in both versions.
Where can I find the exact RTP of a specific version?
- Open the 'Info' or 'Rules' section within the slot. There, the exact configuration set by the operator is indicated. If such information is not available — request it from the casino support service.
Is there a difference in the gamble feature between the versions?
- The mechanics are completely identical: you guess the color of the card, 50 to 50, up to five consecutive wins. The difference is only in the visual design of the button.
Which version is better for playing on a smartphone?
- Definitely Deluxe. It is originally adapted for HTML5, correctly scales in portrait and landscape modes and does not require Flash emulator.
Can free spins be retriggered during the bonus time?
- Yes, in both versions three Book symbols during free spins add another 10 spins. The theoretical limit in current builds is not available.
Is it worth switching from Classic to Deluxe for a higher RTP?
- The difference in RTP is negligible and in the long run practically unnoticeable. The switch makes sense if you value an updated interface and mobile optimization.
