Book of Helios Demo

Here is a demo of the online slot so that you can try it out before spending any real cash on it.

Book of Helios RTP and Wagering

As we mentioned, the Book of Helios was developed by Betsoft who made another game similar to many others out there. We’ve seen many favourite games among players developed with a similar-looking quest-like theme.

The slot game was just released and although it is so new, it’s quite simple in its approach. The graphics are alright, nothing special but nothing bad either. Players can get winnings from the 5 reels and the 3 rows.

Paylines go from left to right with a total of 10 possible ways to win. In all honesty, they could have done more to make the base game layout a bit more thrilling, now it looks like another game without too much imagination applied to it.

The Book of Helios slot is played with an RTP of 95.58%, a number that is pretty decent. Most new games seem to be around 96% with some exceptions.

It’s a slot machine that highly volatile and all wins are spread out accordingly, it does, however, come with quite a high hit percentage, 35.03%. But bear in mind, that these hits are commonly quite small in value.

While the Book of Helios slot, you can get a maximum win of 20,186x your stake. A decent number for a regular video slot. In order to get started with the slot in your online casino, you’ll have to place a minimum bet of $0.1. The maximum stake is $10, meaning the betting range isn’t the largest when put in comparison to other online slots.

Symbols and Audio & Video Design

The Book of Helios slot game has graphics and a design that in our opinion is a bit dull. While keeping in mind that the game was released in late June of 2022, we’d expect more.

The free spins bonus doesn’t do much to add exciteness to the game’s design or graphics but rather goes along the same lines as the base game.

Betsoft that released Book of Helios probably knew about the former successes within the ‘Book of’-themed slots. Because this game doesn’t do much to innovate the industry.

There’s a soundtrack reminiscent of older action movies, sure, it fits into the whole theme of the game. During the free spins feature, the music intensifies.

Book of Helios comes with different paying symbols and only one special symbol.

The low-paying symbols are, as commonly seen, 10 through Aces. You win by creating combinations of at least 3 of the same symbol from left to right. You can get anything from 0.20x the stake to 8x the stake, should you land 5 aces.

The pay symbols with higher values include a Whip, a Crossbow, a female character and Helios himself. Getting 3-5 of the same will pay anything between 0.5x – 20x the stake.

The special symbol featured in the game acts as both a wild symbol and a scatter symbol. The symbol is the Book of Helios itself, and getting 3 or more will activate the free spins bonus.

Bonus Features

All the best online casinos want slots that thrill their players. Book of Helios is kind of dull but fun at the same time, it has a bonus round and it does pay out fairly well. We could have asked for more thrill in the base game, but one can’t ask for everything!

There are actually only three bonus features in this game, the free spins feature, the expanding symbols and the special symbol within the bonus round. They’re all connected in a way.

Let’s check out the bonus feature in this online slot.

Free Spins Feature

Getting into the bonus rounds is what most casino games are about. This is where big wins are won and where the fun begins. In the Book of Helios, there are two ways of entering the bonus round.

You can play and get 3+ scatters, Books, to activate the free spins feature. The bonus buy feature is also present, meaning players can skip the regular base game and pay extra to enter the real fun.

When you get into the free spins round, you’re awarded 10 spins and a special symbol.

Special Symbol

The special symbol is worth more during the bonus spins and is shown at the start. If you hit a minimum of 2 special symbols that create a win, they’ll expand vertically to cover the entire reel. Getting 3 anywhere on the grid will also expand the symbols vertically. This, as you can imagine, opens the door for good combinations.

If you get 4 for instance, almost all of your grid is covered.

Expanding Symbols and Win Multiplier

During the bonus game, you’ll also come across the Book of Helios once more. It still acts as a wild symbol, but now it expands too to cover the reel vertically.

After it has expanded, it reveals win multipliers that are applied to the game round. If you’re lucky, you can cover the full grid and get a max win multiplier of 5x the win.


Unfortunately, this game does not offer any kind of Jackpot. However, the 5,000x potential max win is quite high compared to other slot games. Keep in mind that you have a chance of winning if you trigger the free spins.

Book of Helios Biggest Wins

At the time of writing this slot review, the game has only been active for a couple of days. Due to this, no reports of wins big enough to mention have surfaced. But there will surely be some larger wins in this game thanks to the bonus feature.

If someone manages to land the max win of 20,168x the stake, we will be the first ones to mention it!

Summing up this Book of Helios slot review leaves us wishing for more. It’s an online slot where players can take part in yet another ‘Book of’ story. The base game doesn’t really offer anything thrilling at all, just 5 reels and 3 rows that are spinning. You’ll definitely sit there waiting to enter the bonus game.

The free spins feature, on the other hand, does offer a bit more fun. Thanks to the expanding symbol, we can create loads of winning combinations that prove to be quite lucrative.

Book of Helios comes with a maximum win of 20,168x the stake, and has high volatility with most bigger wins being won in the free spin bonus game.

Fans of the other ‘Book of’-games will probably try this one as well. For us, it wasn’t a favourite.

Try it on with stakes from $0.1 to $10, the RTP is decent at 95.58%. Keep in mind though, that you’ll need to be lucky to win big. Players from Canada who enjoy these slots should give it a go, maybe you’ll cash in on Helios himself!
