Book of Helios

Book of Helios is a video slot developed by Betsoft that operates on a structure of 5 reels, 3 rows, and 10 fixed paylines. The theme revolves around Greek mythology, featuring the god Helios and the explorer Olivia Brave as protagonists, high symbols that combine with classic elements such as bows, whips, and royal cards. The "Book of Helios" symbol acts as both Wild and Scatter, able to substitute for other symbols and trigger the free spins round when three of these books appear on the reels.

During the free spins feature, 10 spins are awarded, and at the start, a symbol is randomly chosen to become Expanding across the height of the reel. Additionally, if books appear during this round, they expand vertically and reveal a multiplier ranging from 1× to 5× on wins that are part of combos with the special symbol. The minimum bet is designed for casual players while the maximum allows for higher stakes, accommodating different playing styles.

It also includes a "Buy Feature" that allows players to purchase direct access to the free spins round, thus avoiding the wait for Scatter symbols to appear in the base game. Visually, it features detailed graphics, an ancient temple setting with dramatic light and fire effects, and a design that appeals to fantasy and adventure. Book of Helios is a high volatility title, which means that big wins may be less frequent but larger in size when they occur.

You can try it for free in demo mode or play it for real money.
