Book of Helios

Harold Anderson

I tried Book of Helios and found the slot uses 5 reels and 10 fixed paylines, following familiar ‘Book of…’ mechanics. The theme centers around ancient gods, with both Olivia Brave and Helios present. The game features a free spins round where one symbol expands to cover the reels, which adds some variation to the gameplay. The maximum potential win is 20,168x, but higher volatility means winning combinations do not occur frequently—especially outside of bonus rounds. The RTP is set at 95.58%. Navigating through features and settings is straightforward. If you want more information, see this machine slots online - Free slots online page.
