Book of Helios Slots

Get ready to join forces with acclaimed heroine Olivia Brave on an adventurous and legendary quest in Book of Helios, a video online slot game crafted by leading provider Betsoft and released in June 2022.

The theme revolves around Greek mythology, with Helios—the Sun God and one of the Titans—as the inspiration. He drives his chariot across the sky from east to west by day and sails the ocean at night in a huge cup. This game is part of the popular Book of series and is full of potent bonus features like free spins, expanding symbols, win multipliers, and a buy feature. These elements combine to provide dynamic and potentially lucrative gameplay. The maximum win potential is 20,168x your stake.

Gameplay

The gaming grid features 5 reels, 3 rows, and 10 fixed paylines. Wins form from left to right across the paylines. The reels sit in the middle of a grand Greek temple, flanked by magnificent stone horses. The 3D graphics deliver a vibrant, colorful comic book aesthetic, with background music perfectly matching the mythological theme. Animations impress, especially Helios shouting victoriously while riding his burning chariot.

Bets range from $0.10 to $10 per spin, suiting a wide range of players. The Autoplay button lets you automatically set the number of spins—handy for managing budgets or enjoying hands-free play.

Access the paytable, rules, and features via the menu to familiarize yourself with the game.

Payouts require 3 to 5 matching symbols on a payline, starting from the leftmost reel.

Symbols and Payouts

The Book symbol serves as both Wild and Scatter, appearing on reels 2, 3, and 4. It substitutes for any regular symbol to complete wins and triggers Free Spins as a Scatter.

High-paying symbols include Helios, Olivia Brave (the female explorer), crossbow, and whip, offering 10x to 20x your stake for five of a kind. Low-paying card symbols—10, J, Q, K, A—pay 5x to 8x for five of a kind.

The RTP stands at 95.58%, below industry average, paired with high volatility. This favors bold players chasing big wins via bonuses, though expect dry spells. Novices should play cautiously.

Bonus Features

Land 3 Book symbols to trigger 10 Free Spins. A randomly selected symbol expands to cover entire reels, paying anywhere regardless of adjacency.

During Free Spins, Book symbols carry 1x to 5x multipliers that stack and multiply together on wins. If the expanding symbol and a Book land on the same reel, the Book expands instead.

The Buy Feature lets you skip to Free Spins for 65.5x your stake.

Mobile Compatibility

Book of Helios is fully optimized for mobile devices. Enjoy the fiery adventure on desktops, iOS, Android phones, or tablets—anytime, anywhere.
