Base Game Mechanics
Book of Helios does not use cascades, nudges, or quick spin. The Book symbol acts as both a wild and scatter. As a wild, it substitutes for all other symbols to help form line wins.
There are no adjustable paylines or manual gamble features. All gameplay in the base game is straightforward, focusing on line wins and wild substitutions.
Spin and Watch for Wilds
Start spinning and look for Book symbols on reels 2, 3, and 4. These wilds can help complete winning lines during the base game.

Wilds

When a Book symbol lands during free spins, it expands and reveals a random multiplier of 1x to 5x, applied to any wins it helps create.
