Book of Santa is a five-reel slot machine with 10 paylines. Players can set their bets as they please.
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
The graphics of the Book of Santa slot are high quality and themed around Christmas. The game screen is full of Christmas decorations, and the reels are surrounded by snow and lights. The symbols on the reels include traditional Christmas elements such as Santa Claus, a Christmas tree, gifts and bells. The soundtrack includes cheerful Christmas melodies, which add to the authenticity of the gaming experience. The most valuable symbol in the game, which can bring significant wins when five symbols appear on a payline, is Santa Claus. At the maximum bet, it can bring players up to 5000x the value of the line bet. The Book serves as both a WILD and Scatter symbol. It replaces all other symbols in the game and helps to form winning combinations. Three or more of these symbols activate the free spins bonus game.
