Join our adventurous researcher as he leads you to a world of stars featuring Helios, the Sun God, Nyx, the wise owl and the Book of Stars. Spin the reels to unlock the secrets of the starry night sky.
Free spins with bonus symbol
See the Book symbol land three or more times anywhere on the reels and 10 free spins will be awarded. An extra bonus symbol will come into play, and is randomly selected on your first free spin. Should it trigger a win, it will expand to cover all reel positions. A continuous winning combination will be formed and your win amount depends on the bonus symbol, which holds the same value as per the normal game.
