The courageous Olivia Brave has set her eyes on the secret temple of the Greek sun god Helios in the Book of Helios slot game from Betsoft.

Wild and Scatter symbols are there, but the Free Spins round with Expanding Symbols and the potential for big wins is surely the game’s best feature.

The Book of Helios slot game is set in ancient Greece and displays the Greek god Helios riding his fire chariot pulled by stone horses in his quest for incredible victories. Along with the fiery Helios, the game also stars a fearless explorer, Olivia Brave, who sets out in search of a temple devoted to the sun god for its riches. And you are going to accompany her as she enters Helios’ territory!

The designers have captured the mythological aspect brilliantly, and the gameplay is brought to life by an orchestral soundtrack that adds a thrilling layer of depth. The extensive use of stone materials stretches to the detailed backdrop surroundings and represents the inside of the temple with outstanding artistry.

Considering that it’s a 2022 title, we’d say that the graphics are a bit dull. Overall, the Book of Helios online slot has a solid theme – but it may disappoint gamers with its low RTP.

Once you’ve entered the game, set your stake before riding on the magical fiery chariot. The controls for the game are neatly placed beneath the grid for easy access. You can place bets between 10 and 10,000 coins for each spin by using the +/- keys.

Then, press the spin button in the lower right hand to find out where these adventurous reels will take you. You can also use the Autoplay mode if you become weary of spinning the reels manually. All you have to do is select the number of automatic spins—from 5 to 100—and the cost of each spin.

The ten fixed paylines in the Book of Helios video slot allow you to create wins that go from left to right. So, the winning combinations must consist of three or more symbols positioned on adjacent reels starting from the leftmost side. In addition, getting two of the high-paying symbols will also result in a win.

The wild symbols in the game act as a stand-in for any regular symbol, allowing you to create more lucrative combinations. Lastly, you can read the game rules and learn about the payouts of each symbol by clicking the “i” button.

Book of Helios Slot Payouts & Symbols

Book of Helios Paytable

Expect to encounter artistically made symbols when playing the Book of Helios slot game. These include five lower-paying symbols from 10 to Aces, paying between 0.20x and 8x the stake when you match three to five of a kind. But the real excitement lies in the four high-paying symbols like a whip, a bow and arrow, Olivia, and the mighty Helios himself as the most valuable. You can get anything from 0.5x to 20x the stake if you match 2 to 5 of these symbols.

As the Book of Helios is a book-style slot, you won’t be surprised to learn that the only special symbols are book symbols. Although offering no rewards, this symbol serves as both the wild and scatter symbols and lands on only the second, third, and fourth reels. These symbols perform dual tasks completing wins and activating the Free Spins feature, where you’ll get a special expanding symbol that we’ll discuss in more detail below.

Book of Helios Bonus Features

Although Book of Helios doesn’t provide many bonus features, the ones it offers are those we’ve seen in other slots of this kind in the past. Everything here revolves around a single free spins bonus round with a few special symbols that boost gameplay and prizes.

Free Spins

Book of Helios Free Spins

The Book of Helios symbols hold great importance because landing three of them once unlocks the free spins feature. At the start of the game, you will get ten free spins and an expanding symbol will be picked randomly. Each special symbol featured on these reels expands vertically and covers an entire reel if it occurs on 2+ or 3+ reels with the potential to create a win. The additional advantage of this symbol is that it can pay out even if it is not directly adjacent to another one on the reels.

Yes, there is still more to this feature; the appearance of book symbols acting as the wild symbol. If the helios book symbol comes on the display in free spins, it will cover the associated reel and reveal a random multiplier while retaining its substituting role. The multipliers only apply to the full reel and range from 1x to a max win multiplier of 5x.

Unfortunately, you cannot re-trigger the free spins because the books do not act as scatters during this bonus. Compared to Book of Dead and Legacy of Dead, the Book of Helios slot focuses less on respins and more towards big payouts; as explained by the role of the scatter/wild symbol above.

Bonus Buy

Book of Helios Buy Feature

If you want to go directly into the thrilling Free Spins bonus, you can select the Buy Feature option. It enables you to skip the base game and pay to jump right into the action. To use this feature, click the shopping cart icon located below the reels. The game will determine the price of this feature based on your current stake, which is 65.5x your bet.

Book of Helios Winning Odds: RTP & Volatility Ratings

Each online slot game has a specific statistical model, and it’s critical to understand these intricate details to gamble responsibly. So, when it comes to the Book of Helios RTP, it is set at 95.58%, which does not excite us because it does not even reach the industry average of 96% assigned for online slots. It leaves a 4.42% house edge for the casino to take from wagers over a long period of play. This RTP rate isn’t terrible, although we had hoped for more from the software provider Betsoft in this area.

The high volatility of the Book of Helios slot makes it a good option for gamblers who like to take risks and look for bigger payouts. Always remember that there is a greater probability you may lose cash faster, but that’s just because high volatility slots provide more opportunities to win big than medium or low volatility slots. It takes a lot of patience to achieve those significant victories, as these games do not offer regular wins.
