Book of Ra Deluxe Buy Bonus Slot Review
Novomatic took the slot that defined a whole genre and bolted a buy button onto it. Book of Ra Deluxe Buy Bonus keeps the desert-tomb hunt, the expanding symbol, the 92.13% RTP and the high-volatility sting that regulars already know, then hands you a shortcut straight into the free spins. For anyone who has sat through 200 spins waiting for three books to drop, that single change rewrites how you play. This is still the classic Egyptian explorer slot at heart, just with less waiting and a steeper price of admission.
Theme & Design
The setting has not moved an inch since the original. You are the lone adventurer in a fedora, poking around a torch-lit tomb, and the reels frame him beside a pharaoh's mask, a golden idol of Isis, a scarab, and the gilded book that runs the whole show. Novomatic kept the visuals deliberately plain. There is no cinematic intro, no fussy animation between spins, just the warm ochre palette and that unmistakable five-note jingle when the book lands. Some players call it dated. I call it honest. The look tells you exactly what you are getting, and the game never pretends to be anything fancier than a tight, old-school payline slot.
Symbols & Payouts
| Symbol | Role | 5-of-a-kind payout |
| Explorer (adventurer) | Top high-pay, pays from 2 | 5,000x line bet |
| Pharaoh's mask | High-pay | 2,000x line bet |
| Golden Isis idol | High-pay | 750x line bet |
| Scarab | Mid-pay | 750x line bet |
| A / K | Low-pay royal | 200x line bet |
| Q / J / 10 | Low-pay royal | 100x line bet |
| Book | Scatter + Wild, expands in bonus | 200x total bet (5) |
The adventurer is the one you want stacked. He pays on two of a kind, which softens the dry spells, and a full line of five is where the real money sits. Card royals fill the gaps and rarely cover the bet on their own. Everything else hinges on the book.
RTP, Volatility & Specs
The headline number deserves a flag before you spin. At 92.13% this version runs well below the original Deluxe release, so the buy button is paying for convenience, not for better odds. Variance is high, which means long flat stretches broken by the occasional screen-filling expand. Here are the details worth knowing that the page above does not spell out.
| Spec | Value | Note |
| Free spins awarded | 10 | Fixed, no matter how many books trigger |
| Max free spins | 20 | One retrigger cap |
| Expanding symbol | 1 random symbol | Chosen before the round, fills its reel |
| Gamble feature | Yes | Card-colour double-or-nothing on line wins |
| Game family | Book of Ra series | Buy-bonus edition of the Deluxe format |
If you have played the lower-paying Book of Ra slot on our platform, the maths here feels familiar, just thinner at the top. Set a session budget before you touch the buy feature, because the cost adds up fast on a quiet run.
Buy Bonus & Free Spins
This is the whole reason the game exists.
Bonus Buy
Instead of fishing for three scatter books, you pay a fixed multiple of your stake and drop straight into the round. The price scales with your bet, so a $1 spin and a $5 spin cost very different amounts to trigger. It is a blunt tool, but on a high-variance title it saves the grind that puts so many players off the base game.
Free Spins & Expanding Symbol
You get 10 free spins, and the magic is the expanding symbol picked at random before the round starts. When that symbol shows up, it stretches to fill its entire reel and pays as if it landed on every position, ignoring the usual left-to-right rule. Draw the adventurer and a single good spin can return more than the buy-in many times over. Draw a card royal and the round can fizzle. The bonus retriggers if three more books appear, capping the round at 20 spins. That randomness is the gamble inside the gamble, and it is what keeps the feature tense rather than predictable.
How to Play
Pick your stake, decide whether to spin for the books or buy in, and let the 10 fixed paylines do the rest. Wins pay from the leftmost reel except the book, which pays anywhere. There is a gamble feature on line wins, a card-guess double-or-nothing that has been part of this family forever. It is pure coin-flip, so treat it as a bit of fun, not a strategy. Players who enjoy this style of book hunt often line it up next to the Book of Dead demo for a side-by-side feel of the same mechanic done by a different studio.
Pros
- Buy feature removes the long grind that defines the base game
- Expanding adventurer can clear the screen in a single spin
- Simple 10-line structure that anyone can read at a glance
- Familiar, proven format with decades of trust behind it
Cons
- 92.13% RTP is stingy compared with other versions of the same game
- Buy-ins get expensive quickly on a cold run
- Visuals and sound have barely changed in years
Verdict
Book of Ra Deluxe Buy Bonus is built for one type of player: the regular who loves the expanding-symbol free spins but has run out of patience for the chase. The buy button delivers exactly that, and the expanding adventurer still produces the kind of full-reel hit that made this series famous. Just go in clear-eyed about the 92.13% return and the cost of repeated buy-ins, then try a few base-game rounds in demo first to learn the rhythm before you commit real funds. If the book theme is your thing, the spookier Book of Madness and the Egyptian Symbols of Egypt slot sit one click away on our platform.
