Book of Flames Extra Hold & Win Demo & Review

How to Play Book of Flames Extra Hold & Win Slot – Bonus & Gameplay Explained

Book of Flames Extra Hold & Win uses a 5×3 setup with 9 fixed paylines. The listed minimum bet is €1.00 in one early demo listing, while the RTP shown on live casino pages is 94.00%, which already tells you this is being released in operator-specific versions and may not be identical everywhere.

This is not a plain Book slot. Early game descriptions point to a mix of Free Spins and Hold & Win, which is where the “Extra” part seems to come in. The book symbol appears to act as a scatter during Free Spins and can award additional spins, so the game is not relying on a single one-stage bonus. That usually means the slot has two different payout routes: the standard book-style bonus flow and a separate lock-and-respin style feature with jackpot potential.

The Hold & Win side is also backed by in-game jackpots in multiple early listings. That matters because jackpots in this format usually sit inside a respin feature where special symbols lock in place and fresh symbols reset the counter. I could not verify the exact trigger count or the exact jackpot labels from a reliable current rules page, so I would not invent them. What is clear is that jackpots are part of the feature package rather than something random in the base game.

Free spin counts are not clearly disclosed in the public sources I could verify. Bonus multipliers are also not clearly listed, though one early promotion mentions a max multiplier of 9,561x and another mentions max win at 2,100x, which is a big enough gap that the safest reading is version variance or inconsistent early promo data. I would treat the exact top-end figure as unsettled until the final rules page is broadly available.

How Book of Flames Extra Hold & Win Slot Plays – Volatility, Hit Frequency & Bonus Behavior

The volatility is being described as high in early release listings, and that fits the structure. A 5×3, 9-line slot with Book mechanics and a Hold & Win layer is not built to drip-feed constant value. It is built to miss for stretches, then try to make the session back through one stronger feature cycle.

Hit frequency is not publicly disclosed. Bonus frequency is not publicly disclosed either. That leaves the feature mix as the best clue to how it behaves in practice. High volatility plus Hold & Win usually means the base game does not carry the slot for long. You are mostly waiting for the right trigger, and once you get there, the session depends on whether the feature extends properly or dies early.

The Book side should make the game feel more familiar to Novomatic players than a pure coin-respin slot would. The Hold & Win side should make it a bit more lumpy than a standard Book release. So I would expect long quiet patches, then a feature that either pays middling money or does most of the work for the whole session. This does not look like a bankroll stretcher. It looks like a bonus-chasing slot with a tighter base game.

For player suitability, this one is better for players who already like Book slots but want more volatility and a second feature path. If you prefer smoother play or a lot of low-level hit activity, the 9-line setup and high-volatility label point the other way.

Book of Flames Extra Hold & Win Bonus Features – Free Spins, Jackpots & Special Symbols

The Book symbol appears central to the Free Spins feature. Early listing text says it shows during Free Spins as a scatter and can award additional spins. That suggests the bonus is meant to keep extending rather than simply pay a fixed short round and stop. What affects the result most in this kind of setup is how often the retriggers land and whether the chosen expanding symbol is a premium or a low-value icon, though I could not confirm the exact expanding-symbol rule from a current official paytable.

The Hold & Win side is where the extra punch should come from. In this sort of mechanic, special symbols lock, the remaining positions respin, and each fresh land resets the counter. The payout impact depends on your starting board, how quickly new symbols arrive, and whether jackpots are tied to collected symbols or full-grid progression. Early listings confirm in-game jackpots, but not the precise collection rule. So the practical read is simple: this is the swingier side of the game, and probably the reason the volatility is marked high.

There is no sign of meaningful player influence inside either bonus. You are not picking books, choosing between free-spin modes, or managing a meter. The only real decisions are stake size and whether the version you are playing has a different RTP or max-win cap from other operators.

In practice, that makes Book of Flames Extra Hold & Win the kind of slot where the features matter far more than the base game. If the Free Spins retrigger and the Hold & Win holds up properly, it can carry a session. If not, the 9-line base setup is likely to feel pretty thin.

Final Verdict – Is Book of Flames Extra Hold & Win a Good Slot?

Book of Flames Extra Hold & Win looks promising if you already like Novomatic’s Book games and want something rougher around the edges. The Hold & Win layer is the right kind of add-on for that. It gives the slot a second way to produce a decent hit instead of leaning entirely on Free Spins.

The weak spot is data clarity. Right now, the published details are patchy. RTP is showing 94.00% on live pages, volatility is being flagged high, paylines are showing as 9, and the top-win figures are inconsistent across early listings. That is enough to judge the shape of the game, but not enough to treat every number as settled.

My read is that this is probably one for players who do not mind a dry base game as long as the bonuses have some bite. If you want a softer Book slot, this may feel too top-heavy. If you want a Book game with a bit more tension and a jackpot route, it should be the better fit.
