It’s time to admit: we all, players and casino staff alike, love Indiana Jones-knockoff games, or else no provider would care to produce so many of them! Indeed, the phenomenal success of your typical ‘Lara-meets-Indy’ is something future sociologists will explore, but for now, let’s focus on the online slot machine itself: Please welcome Book of Helios! The game features a classic 5-reel, 3-row layout with 10 paylines. Like any wrathful heathen fire god, Helios brings high volatility, offering a 'high risk, high reward' experience. Try playing the demo version on our site or play for real money to open yet another chapter in the adventures of Indiana’s progeny!
