Book of Helios slot bonus features

The book symbol

The Book symbol is both: the Wild and the Scatter at the same time! It does the following: One, landing on three Books anywhere on the grid will trigger the 10 Free Spins Bonus feature. And two, it replaces other symbols on reels 2, 3, and 4, to create winning paylines! 

Free spins feature

You can either purchase the 10 free spins feature (explained below) or wait until three or more Books (the Scatter symbol) appear anywhere on the 5×3 grid. When this happens, the special feature is triggered. You are rewarded with 10 free spins, during which 2 main events payout big:

  • The Book symbol covers an entire reel by expanding vertically and serves as a multiplier of winnings (x1 to x5).
  • A random symbol will be chosen at the beginning of free spins. When 2 or more appear on the reels in a winning payline, they expand vertically, paying on all lines played. 

Buy bonus option

Tired of waiting for the bonus spins to be triggered? Just buy the damn feature! This way, you save time and money and increase the odds of hitting a big win during the bonus rounds. Buy Feature will reward you will 10 free spins, whose value is determined by the amount you are willing to spend for the purchase!

Book of Helios slot review summary

In terms of numbers, we can say that the Book of Helios is worth risking some money for! It rewards players with many different features, and the RTP is 95.58%, which is relatively high! Who should not play this game? If you’re a high roller, maybe you should think about it!

This slot allows players to place bets whose value per spin starts from 10 cents and reaches up to €10. Given that it is a highly volatile slot, it is reasonable to keep your spins at a low to medium value. However, it prevents high rollers from playing with big bets. This might not always be the case, as certain casinos may offer larger maximum bet limits, so always check with your local casino first!

Overall, we like the game for its simplicity, and because it is powered by a well-liked game studio like Betsoft, chances are you will find it in every online casino! 


    Book of Helios has a theoretical return to player (RTP) of 95.58%, which is better than 80% of all slot games! So you can say this is one of the high-paying ones!

    Although it depends on the casino, most sites will allow you to play on the Book of Helios slot with bets as low as 10 cents. The maximum single spin value is €10, but that may also vary.

    Not for no reason, it was listed as one of the best slots of 2022! Book of Helios by Betsoft comes with an RTP of 95.58%, has a potential win set around 20.000 times your bet value, and allows players to purchase bonus features within the game!
