Santa's Magic Book is a special symbol in the Book of Santa and acts as the wild and scatter in this game. As a wild symbol, it can substitute for other symbols to help set up winning combos.
However, the wild symbol also acts as a bonus symbol, and if you find three or more anywhere on the reels on the same spin, you will trigger the free spins bonus round with 10x free spins to start and a special, randomly chosen Expanding symbol.
Expanding symbols only expand after any other spin wins have been paid out and will cover the entire reel they appear on when enough symbols are present on the reels to trigger. An additional ten free spins can be won during the free spins round by finding 3+ extra scatters.
There is also a risk game in this slot. The user will have a choice between risk and gain. If he chooses the first, five playing cards appear face down in front of him. The task is to select a card higher than the dealer's card. In luck, the slot can increase the winning amount by ten times.
