Free spins with bonus symbols
The BOOK OF STARS will show you the way to glittering treasures in the starry sky: Land 3 or more BOOK symbols anywhere on the reels to trigger 10 free spins with an extra bonus symbol. Your current bet level in the normal game is also used in the free spins.
A bonus symbol is randomly chosen when you enter your first free spin. As long as the bonus symbol appears enough times to trigger a win, it will expand out and cover all positions on the reel. Following this, all other reels will fade away, so that a continuous winning combination forms and you will receive all line wins.
The RTP is 95.16%.
