Book of Helios FROM Betsoft

Book of Helios slot by Betsoft is an epic Greek themed story prepared for the summer of 2022. The story follows Olivia Brave who travels to ancient Greece to discover the secrets of Helios. Helios himself appears on the grid with his fiery chariot and whisks Olivia (as well as us, the players) to an epic adventure featuring free spins, expanding symbols, 10 paylines, and superb 20,168x wins.

Book of Helios slot is a 5-reel slot with 10 paylines by Betsoft. The game came out at the end of June 2022, just in time for summer vacation. From what we’ve seen, this is a Greek-themed, fantasy filled video slot telling the story of Helios, or rather, the Book of Helios. Olivia Brave, we are guessing, is the supposed Betsoft version of Cat Wilde, a brave explorer who is not afraid to dive deep into this mystery and discover the secrets of Helios. She probably did not expect for Helios himself to pop up on the grid, as he does often as the highest-paying icon.

The mad-looking Helios and the beautiful Olivia are the only two characters in this story, and they are joined by two other premium icons (whip and crossbow) and low-value tiles (card royals).

Betsoft’s slot is extremely volatile, and even its RTP rate hints at how not-player-friendly the game can be when it comes to payouts. Sure, you stand to gain up to 20,168x the stake, but at the cost of losing too much as the RTP rate for Book of Helios is 95.58%.

The main attraction here is the Free Spins round which is unlocked by three Scatters/Wilds. If you want to play the Book of Helios slot for real money at Betsoft casinos, you can do so for only $0.20 per spin. Conversely, the highest you can wager in the game is $20. We recommend four top Betsoft casinos right here where you can play Book of Helios slot for free and for real money on any device you like.

Book of Helios online slot must have one of the highest win potentials in the Betsoft slot lobby. We are not used to having this big of a win potential from this company, but you won’t see us complaining!

The highest sum you can win in Book of Helios online slot is 20,168x the stake, and that can be done mostly via Free Spins. The highest paying icon in the game is Helios who pays 20x for a full sequence of 5 matching tiles, while the second-best symbol is Olivia paying 15x.

The game is very volatile and comes with a 95.58% RTP rate.


Look, we won’t pretend like Book of Helios brings forth features we’ve never seen before. It doesn’t. What it does is pack the familiar Free Spins, Bonus Buy, and Expanding Symbols into one potent combo that plays out on a breathtaking screen. That’s right, folks – the design, visuals, and sounds, are by far the best part of the whole Book of Helios slot experience.

Regardless, you will surely have fun with the Free Spins after you unlock them using 3 Scatters. The Scatter is the Wild of the game, but during base spins, you consider it a Scatter. Three open the Free Spins mode with 10 gratis rolls. Now what’s interesting about this feature is that it always has a special symbol that is chosen at the start of the round to be an Expanding symbol. Whenever it appears on 2+ reels and is capable of forming a win, it will Expand to cover an entire reel. On the other hand, if this happens with the Book Scatter, it acts as a Wild and then Expands vertically to throw in a random 1-5x Multiplier.

You cannot retrigger the feature. But if you want to play Free Spins and cannot wait for them, buy them via Buy Feature for 65.50x.


Betsoft’s Book of Helios slot is available in all Betsoft casinos for only $0.20 per spin! You can explore ancient Helios lore with Olivia Brave and win up to 20,168x the stake – but be careful about the extreme volatility and 95.58% RTP.

The game might not be a spectacular invention, but we do appreciate the design and effort that went into creating this visual masterpiece. Overall, it’s a cool slot release from Betsoft you should at least try if you are into Greek mythology. It is also a Betsoft slot with one of the highest win potentials amounts we’ve seen in a while. Stay tuned for more information and new releases like Safari Sam 2 and Gemini Joker from Betsoft here at CasinosOnline.
