RTP & Volatility
The Return to Player percentage of the Book of Helios is disappointing at 95.58%. However, it's important to note that the hit frequency of 35.03% is more than enough to compensate for the slight RTP.
Symbols & Theme
The Book of Helios is a physical symbol that acts as the wild and substitutes for other symbols in the game. It also has the ability to create winning combinations by substituting all of the pay symbols.
The lowest pay line in the Book of Helios is the card royals from 10 to A. These are used to provide top payouts of 8x for 5 of a kind. There are also several high-value symbols that are featured in the game such as the Crossbow, Olivia, and the Helios.
To get the most out of the Book of Helios, you should only land two of the high-value symbols on each of the pay lines. This will allow you to create winning combinations.
Free Spins
When three or more Book symbols land on the reels, this feature will expand into a free spins round. In this round, you'll be able to play at the same bet level as the one that resulted in the win. Once the necessary scatters appear, you'll receive 10x your free spins.
Expanding Wilds
Before the free spins round begins, the mechanics randomly chooses a special paytable symbol to trigger this feature. This symbol can expand across the reels to provide additional prizes. After winning, the special symbol will start to drive the other symbols into action.
If the special symbol appears on more than two reels, it can expand across the entire length of the reels to create winning combinations. Although it can pay like regular symbols, it does not need to land on any paylines to trigger this feature.
Another steal in this feature is that if another Book symbol lands on the reels, it can expand to cover all of the reels to create additional wins. However, the multiplier for this feature only works for full-reel wins.
