The reels feature card ranks, weapons, equipment, Olivia Brave, Helios and the special Book of Helios symbol.
The Book acts as both Wild and Scatter: it substitutes for regular symbols and helps trigger Free Spins.

The Book of Helios interface is built around a classic 5×3 grid with 10 fixed paylines. The number of paylines cannot be adjusted separately.
In the project version, the bet range is listed as 0.01–1.00. Some operators may display the monetary scale differently, so it is worth checking the limits directly in the game client before playing for real money.

Book of Helios Reviews
Below are opinions about Book of Helios. They help you understand which features, mechanics, pace, and design may be important when evaluating the game.
What I like most in Book of Helios is the combination of a classic Book bonus and multipliers. When the Book expands and reveals ×3 or ×5, a standard Free Spins round becomes much more interesting. The ability to multiply several values together adds strong potential, especially when multiple Books expand on the same spin.
Yes, the Book Multipliers are what distinguish this bonus from the standard setup with a single Expanding Symbol.

The game will feel familiar to Book-slot fans: 5×3, ten paylines and one randomly selected expanding symbol during Free Spins. But the Book can expand too and receive its own multiplier. I like that the rules remain simple even though the top Max Win reaches 20,168×.
The classic structure is indeed combined here with notably enhanced bonus mathematics.

The Helios and Olivia Brave theme suits the adventure-style Book format well. Free Spins interest me most because the selected symbol can expand even without standard payline adjacency. The downside for me is the 95.58% RTP and high volatility, so trying the demo before real-money play seems useful.
The demo does help you assess the pace of high volatility and the Expanding Symbol mechanic.

I like the Book priority rule: if it appears on the same reel where the selected symbol could expand, the Book takes over the reel and adds a multiplier. That makes the mechanic easy to understand. It is a pity Free Spins cannot be retriggered, so the whole bonus is limited to the initial ten spins.
Yes, the lack of a retrigger makes each of the ten starting Free Spins particularly important.

Book of Helios is fairly classic in structure and will not suit players looking for dozens of different features. On the other hand, the ten fixed paylines, Wild/Scatter Book and Free Spins are immediately clear. The main attraction is the multipliers up to ×5 and the possibility of reaching a combined ×125.
The game’s main depth really comes not from the number of features, but from the combination of the Expanding Book and multipliers.
