Bonus Features and Mechanics

Mystery Symbol Feature

On every single spin in the base game, a random paying symbol is chosen and displayed above the reels. This is the special “mystery symbol” for that spin. If you land enough of these symbols to form a win, they will expand vertically to cover their entire reels after any regular wins are paid.

Free Spins

Landing 3 or more Book symbols awards 10 free spins. Before the round begins, one symbol is chosen to be the special expanding symbol for the entire duration of the feature. However, on every single free spin, a second, random mystery symbol is also chosen to expand. Having two expanding symbols active on every spin dramatically increases the potential for full-screen payouts and hitting the game’s max win.
