Book of Helios Slots
Book of Helios takes you on a treasure hunt in the Greek sun god's temple. The only problem is that Helios is guarding his temple and not too happy that you're plundering it for an ancient book. Follow along as we review Book of Helios slots by focusing on its gameplay, features, RTP, volatility, and more. With payouts worth up to 20,168x your bet, this slot is definitely worth a look.
Gameplay
Developed by Betsoft, Book of Helios features 5 reels and 10 paylines on a 5x3 grid. You need 3 matches of any symbol type in a payline to win. As usual in 'book of' slots, all winning combinations must start in reel 1 and move right.
Graphics & Setting
This game features a temple atmosphere, complete with stone walls, archways, and columns. The middle of the screen has a doorway that leads outside, allowing the sun to shine through. You'll also see an angry Helios along with two red-eyed horses lining the reels. Add some dramatic music, and Betsoft has proven that they can make a book-of slot just as well as anybody.
Symbols & Win Potential
Standard symbols include five royals (A-10), a whip, golden crossbow, female adventurer, and Helios. The Greek sun god pays the most among this group at 20x your bet for five matches. The ancient book serves as the wild symbol and scatter. As mentioned before, the Book of Helios max win is 20,168x your total bet. This is one of the larger max payouts that we've seen while reviewing online slots.
Features
In typical 'book of' fashion, this game has free spins with an expanding symbol. You can read about this bonus round and other features below.
- Free spins - You trigger 10 free games by landing 3 books in reels 2, 3, and 4. The game randomly selects one symbol to act as the expanding symbol during this bonus. This symbol will expand to cover its respective reel and pays like a scatter (e.g., reels 1, 2 & 5 would count). These symbols also carry a win multiplier ranging from 1x to 5x the bet.
- Buy feature - The shopping cart icon lets you buy free spins at any point for 65.5x your current wager. If you're betting $2 per spin, for example, you'd buy free games for $130.
Betting Options
The 10 paylines are fixed, but you can change your bet size from $0.20 to $20 per spin. Autoplay allows you to keep the reels spinning for between 5 and 100 rounds. Other options let you turn the background music on/off, sound effects on/off, and use turbo play.
RTP & Volatility
The Book of Helios RTP is 95.58%, which is in line with the industry average of 95-96%. Volatility is high, which is expected with such a large max payout. The hit rate is 35.03%, an above average figure based on our experiences.
