We now complete a trilogy we started building without fully planning it. Legacy of Dead led us to Book of Dead, and now Book of Dead leads us to Book of Ra Deluxe, released by Novomatic under its Greentube studio, with a deluxe version dated to 2010, predating Book of Dead's 2016 release by six years. If Book of Dead was the game that popularized the expanding-symbol Egyptian format, Book of Ra is very plausibly where Play'n GO drew the idea from in the first place, a genuinely older entry in the same lineage we have now traced across three separate titles.
The lowest RTP slot we have reviewed Book of Ra Deluxe carries a 95.10 percent RTP, the lowest figure among every standalone slot we have reviewed on this site, behind Book of Dead's 96.21, Legacy of Dead's 96.58, and every other slot title in our lineup. Only Mega Moolah's 88.12 percent sits lower, and that figure exists for the specific, explained reason of funding a progressive jackpot pool. Book of Ra Deluxe has no such jackpot layer to justify its lower number, it is simply a lower base RTP on its own terms, and we want to be direct about that rather than soften it.
An unusually low maximum bet Alongside the lower RTP, this game's betting range is also the most restrictive we have seen: 0.02 up to 5. Every other Egyptian-themed title in our reviews allows meaningfully larger stakes, Book of Dead up to 100, Legacy of Dead's range unlisted but presumably comparable. A maximum bet of 5 is genuinely low relative to everything else we have covered, and combined with the lower RTP, this paints a fairly clear picture of a game built for smaller, more cautious stakes than its more modern relatives.
Why we think the lineage matters here Book of Ra as a franchise predates the online slot boom that produced most of the titles we have reviewed, with roots going back to physical arcade cabinets in parts of Europe before its various online deluxe adaptations. Reviewing it after Book of Dead and Legacy of Dead lets us say something we could not have said reviewing any of these three in isolation: this specific expanding-symbol, Egyptian-explorer, scatter-triggered free spins format has a real, traceable history spanning well over a decade, and multiple studios have built commercially successful careers on variations of essentially the same core idea.
The mechanic itself, once more Five reels, ten fixed paylines, scatter symbols trigger free spins, and one symbol is selected to expand and substitute across the reels during that round. If you have read either of our other two reviews in this trilogy, this description will sound completely familiar, because the mechanic here is genuinely the same core loop, adapted across three different studios and three different visual styles over roughly a decade and a half.
Being fair about what "older" and "lower RTP" mean together We do not want to imply that an older game or a lower RTP figure automatically makes this a bad choice. Older slot titles were frequently built with tighter betting ranges and more conservative RTP figures as standard industry practice at the time, reflecting different regulatory and technical norms than exist today. A 95.10 percent RTP is still a legitimate, published, verifiable figure, not a hidden trap, it simply reflects an earlier generation's typical numbers rather than the modern standard we have seen cluster around 96 to 97 percent across most of our other slot reviews.
High volatility, and where the entire outcome concentrates As with its two younger relatives, the base game here pays modestly across ten lines, and the free spins round with its expanding symbol carries almost the entire payout potential. The gamble feature is present here too, the same double-or-nothing side option we flagged in Book of Dead, and our position on it remains identical: optional, does not improve your underlying return, and worth using sparingly if at all.
How the three compare, side by side Book of Ra Deluxe: 95.10 percent RTP, 0.02 to 5 stake range, the oldest of the three. Book of Dead: 96.21 percent RTP, 0.01 to 100 stake range, the mid-point release that popularized the format for a new generation. Legacy of Dead: 96.58 percent RTP, unlisted stake range, the newest and highest-returning of the trilogy. If pure value is your priority, Legacy of Dead wins on paper. If you want the widest betting flexibility, Book of Dead's range is unmatched among the three. If you specifically want to play the oldest, most historically foundational version, this is it.
Who this suits Players interested in the genuine history of this slot format who want to play the oldest traceable version in our reviews, and anyone comfortable with a lower maximum stake and a correspondingly lower RTP as the trade-off for that history.
Who should look elsewhere Anyone purely optimizing for return, since both of this game's younger relatives outperform it on RTP. Anyone who wants a wider betting range than the capped 5 maximum here allows.
Our honest take This is the oldest and lowest-returning entry in a trilogy of closely related titles we have now fully reviewed, and knowing its place in that lineage adds real context you would not get reviewing it alone. If you have played Book of Dead or Legacy of Dead and want to see where the format actually traces back to, this is worth trying once, with realistic expectations set by its lower RTP and tighter stake range.
Slot outcomes are random and no free spins trigger is owed after a dry stretch. High volatility guarantees long stretches without the feature round. The gamble feature does not improve your odds. Set a strict budget, never chase a loss, and stop when you planned to. Ages 18 and over only.
A closing thought on reviewing three related games instead of pretending they are unrelated We could have written each of these three reviews as though the other two did not exist, describing the same expanding-symbol mechanic each time as if it were fresh and unique to that specific title. We do not think that would have served you well. Understanding that Book of Ra Deluxe, Book of Dead, and Legacy of Dead form a real, traceable lineage, with genuine differences in RTP and stake range despite sharing a core mechanic, is more useful to you than three isolated write-ups pretending otherwise. If you only read one of these three reviews, we would still point you to this one for the historical context, even though it is not the highest-returning of the three.
