Book of Flames Buy Bonus Slot Review

In 213 BC, Chinese Emperor Qin Shi Huang ordered the burning of all books that didn't serve his regime, in what historians consider one of history's most aggressive attempts at information control. 📚

Scholars who refused to hand over their texts were reportedly buried alive, which was a pretty clear signal that the emperor wasn't open to a second opinion. 🤷🏻

The whole exercise backfired spectacularly. Copies had already been hidden, smuggled, and memorised, and most of the banned knowledge survived anyway. Turns out you can't burn an idea. 🔥

I wonder if Emperor Huang would support Book of Flames Buy Bonus slot from Novomatic.

Gameplay

Another desert, another pyramid, another set of hieroglyphs, another grid framed in gold with fire licking the edges. I know it’s due to the theme, but I wish the studios could change things up somehow to show us something.

I’m not saying it’s off-putting, but a fresh twist would be nice.

While we hold our breath for that to happen, let’s move on to what’s happening on the 5-reel, 3-row grid. Among the high-paying symbols filling the reels, you’ll find: an Indiana Jones wannabee (pays up to 500x for 5), Tutankhamun (200x for 5), Horus, and Isis (both 75x for 5).

The Book takes on the role of both the Wild and Scatter, substituting for all symbols and pays up to 200x for five.

The game runs on the following stats: a 94.06% RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

RTP needs to be considered in conjunction with a game’s volatility rate., high volatility, 10 paylines, a 6,422x max multiplier, and a $321,100 max win. Other than the Japanese yen, both fiat and cryptocurrency are accepted.

Features

FREE SPINS

Landing 3 or more Books triggers 10 Free Spins. Before the feature begins, you’ll spin a wheel to randomly select a Special Expanding Symbol.

During Free Spins, that symbol expands to cover all three positions on any reel it lands on, but only if there are enough symbols in place to form a win. The expanded symbol pays as normal, but also on non-adjacent positions and across all lines.

You can retrigger another 10 spins by landing 3 or more Books during the round. Unlike the Multichance mechanic found in some other Novomatic Book titles, only one Special Expanding Symbol is in play at a time.

BUY BONUS

A Buy Bonus option is available at 90x, taking you straight into Free Spins.

Performance

I didn’t encounter any problems while testing the game.

Maximum Win

Players can place bets ranging from $0.10 to $50. Land the 6,422x max multiplier on a $50 bet, and you’ll secure the $321,100 max win.

Conclusion

Let's be honest about what this game is. A high-volatility game asking you to grind through a dry base game waiting for Books to land can be a tough sell. In a way, this makes the Buy Bonus the game's main selling point.

But 90x is 90x, and if the wheel lands on a J or a 10, you've paid a premium to watch a low-value symbol expand across reels that were never going to move the needle anyway.

There's no way to influence the wheel, which means the Buy Bonus is essentially a 90x lottery ticket for a decent expanding symbol.

When the wheel does land on the Explorer or the Pharaoh, things change. Those are the symbols that make the non-adjacent pay rule worth caring about.

Five-of-a-kind expanding across the full grid pays on every line regardless of position, which makes the 6,422x max begin to feel achievable rather than just decorative.
The retrigger mechanic keeps rounds alive but doesn't add anything new. Unlike Book Hotfire Multichance slot, there's no symbol stacking here, meaning you’ll get the same one expanding symbol whether you retrigger once or five times.
