How Book of Santa works

Book of Santa is a 10-line, 5-reel, 3-row slot. The Book is both the Scatter and the Wild.

Bonus features

Three or more Books trigger 10 free games. At the start a special expanding symbol is randomly selected. After regular wins are paid, it may expand to cover 3 positions on its reel, but only if enough symbols for a win are present. Expanded symbols pay on non-adjacent positions. Free games can be won again during the feature.

Top symbols

Five Santas award 500x the base bet. Five bells or five Books pay 200x, and five stars pay 75x.
