Book of Helios Slots
Book of Helios is a Greek god based slot. Helios himself is the Greek god of the sun. You'll often see him portrayed driving a chariot driven by stallions. He's the centerpiece in this slot! Any slot regulars will be familiar with Greek mythology themed slots, with the most common theme usually being a game based around Olpymus or Zeus, but Book of Helios is unique. It's also part of the acclaimed and popular 'Book of' slot series that focuses on adventure and myth. This game is played on five reels with three rows, and a total of 10 pay lines. This game also comes with a lucrative jackpot award! The luckiest players will win up to 20,168x your stake.
The betting range is very reasonable, perfect for your average gambler. However, high rollers will probably wish this slot's betting range was larger. Nonetheless, if you're of medium income level, you can bet anywhere from $0.10 to $10 per spin. Helios himself is the most valuable symbol, paying out 20x your bet. This game is by BetSoft.
The interface artwork is something else. The game grid is played against Helios himself, and his fire stallions look just as fierce as he does. All around him you can see an array of flames and clouds. We can assume Helios is ascending from the sky, as many Greek gods would. There is a control panel located at the bottom of the game grid, and through the control panel you can adjust the bet, check out the information table, adjust the sound settings as well as manually spin the reels or auto spin the reels. The RTP associated with Book of Helios is 95.58% with a hit frequency of 35.03%.
Symbols
This slot has two special slot symbols. The book operates as the wild symbol, and substitutes to create pay symbols to create winning combinations. The book symbol is the scatter symbol as well! The low paying symbols within this slot include the royal symbols, which include 10, 9, A, K, Q and J. The premium symbols are the whip, the crossbow, Olivia and the helios symbols. If you land two of the premium symbols you can form winning combinations, and if you land five premium symbols you'll receive a payment that ranges from 10x to 20x your bet.
Bonus Rounds
Book Of Helios has a free spins feature that is activated when you land three scatter book symbols on the reel. When the spin-gods smile upon you, you'll land 10 free spins. Another special feature is the Expanding Symbol Feature! This mechanic selects a special symbol to become the expanding symbol before your free spin rounds launch. Whatever symbol is chosen will expand across the reels and reward more prizes! If it displays on more than 2 reels to create wins, each symbol expands vertically across the entire reel. If the book symbol lands as well, it'll expand the entire reel and add multipliers. The multipliers will be 1x, 2x, 3x, 4x or 5x your payout.
The last special feature left to mention is the Bonus Buy option. Basically, with this mechanic you can purchase free spins rather than waiting for them to trigger on their own. As long as you can increase your stake by 65.5x, you can claim 10 free spins.
