Book of Helios

Book of Helios puts a Greek mythology slant on the book-slot formula: Betsoft built a 5x3 grid with 10 paylines, a 95.58% RTP, and a 20,168x max win ceiling that puts it among the higher-end Betsoft titles. High volatility with a 35.03% hit frequency keeps base-game spins active while pushing the big numbers into the bonus buy and free spins phase. The expanding Book Wild mechanic and a 5x multiplier in the bonus define the ceiling. At Wild.io, bonus buy is available, and the game runs across crypto currencies on desktop and mobile.

What is Book of Helios?

Book of Helios is a 5x3 video slot from Betsoft with a 95.58% RTP, high volatility, and 10 paylines. Its top win of 20,168x comes from a free spins round where the Book Wild expands vertically with a multiplier up to 5x, combined with a randomly selected expanding symbol.

Betsoft designed Book of Helios with a bonus buy at 65.5x the stake, making the free spins feature directly accessible. The 35.03% hit frequency is moderate for high volatility, which means the base game produces enough regular wins to sustain play while the expanding Wild and multiplier combination in the bonus phase is what drives the 20,168x top win. The Book symbol handles both Wild and Scatter duties.

Book of Helios Slot Theme & Graphics

Book of Helios draws from ancient Greek mythology, centering on Helios, the sun god, and the heroic warriors who served as his champions. The reel frame uses warm gold and terracotta tones with columns, laurel borders, and parchment textures. The Book of Helios itself is rendered as a sun-disc tome, and the premium symbol art gives the Female Hero and Helios himself animated sparkle effects on winning combinations.

The visual mood is brighter than Betsoft's darker book entries, with a gold-lit temple backdrop and a sun-ray animation that fires during the free spins transition. On mobile, the 5x3 layout and 10-payline grid are compact enough to sit cleanly on small screens, and the bonus buy button is accessible in the main UI without submenus.

Book of Helios Slot Symbols & Paytables

Book of Helios runs 9 paying symbols from card-rank low pays through Greek heroes, with the Book acting as the sole special symbol carrying Wild, Scatter, and expanding multiplier functions.

Low Value Symbols

The low-value symbols are standard playing card ranks, styled with golden Greek letterforms. These are the most frequently landing symbols on the 10-payline grid and form the base-game filler wins. For five of a kind on a payline, card ranks pay up to 8x the stake, which is modest but consistent with high-volatility games where the distribution skews toward the bonus. In the free spins, card ranks are eligible for the random expanding symbol selection, meaning any of the low-value icons can become the expanding symbol that drives the top-end win.

High Value Symbols

The premium symbols are three Greek hero characters: the Crossbow fighter, the Whip fighter, and the Female Hero. These pay more than the card ranks for three-of-a-kind through five-of-a-kind on the 10 paylines. The Helios symbol is the highest-paying regular symbol, awarding up to 20x the stake for five of a kind, and it's the most likely candidate for the random expanding symbol when it fires across two or three reels simultaneously in the bonus.

Special Symbols

The Book of Helios is the sole special symbol, carrying three distinct functions. As a Wild, it substitutes for all nine paying symbols to complete partial payline wins. As a Scatter, 3 or more anywhere on the reels triggers 10 free spins. During the bonus, Book symbols that land expand vertically to fill the entire reel they land on and apply a multiplier of up to 5x to any wins they complete. Separately, one random paying symbol is designated as the expanding symbol for the feature duration, and it expands when three or more appear, creating a dual-expanding setup when both the Book Wild and the random symbol are active on the same spin.

Book of Helios Bonus Feature & Special Features

Free Spins with Expanding Wild and Multiplier

Landing 3 or more Book of Helios Scatter symbols triggers 10 free spins. Before the first spin, the game selects a random paying symbol to act as the expanding symbol for the entire round. On any spin where 3 or more of that symbol land, they expand to fill all rows on their reels. Simultaneously, the Book of Helios Wild itself expands when it lands and applies a multiplier of up to 5x to wins it contributes to. When the Book Wild and the random expanding symbol both activate on the same spin, the reel coverage combined with the 5x multiplier creates the conditions for the game's 20,168x top win. The expanding Wild multiplier can reach up to 5x on a single combination, which is the main engine behind the high ceiling.

Bonus Buy

Book of Helios includes a bonus buy option priced at 65.5x the current stake, which purchases immediate access to the free spins round. This is the primary path for players using bonus buy slots mechanics rather than waiting for the Scatter trigger in the base game. At 65.5x, the cost is in the mid range for book-style bonus buys and reflects the 20,168x ceiling available in the feature. The bonus buy effectively converts the high-volatility base game into direct feature access, making the session structure a choice between grinding the 35.03% hit frequency base game or buying in directly at the higher variance of the free spins phase.
