Book of Santa by Endorphina is a Christmas-themed online slot with a 5x3 reel set and 10 fixed paylines. The game has an RTP of 96.05% and uses a high-volatility format. Players looking for the demo version can play for free to practice before playing for real money and to review the payline structure, bet settings, and bonus features.
The reels feature Santa, bells, stars, sleighs, and standard card symbols, all presented in a festive red, gold, and green style. The Book symbol acts as both Scatter and Wild: three Book symbols trigger 10 Free Games, while five Scatters award 200x the base bet. During Free Games, an expanding symbol can appear and cover three positions on a reel, creating additional winning possibilities on enabled paylines.
The game also includes a Risk Game, where a win can be gambled in a card-based double-up feature, plus a Bonus Pop feature and Turbo and Auto play controls. The free demo version shows the same 5-reel, 3-row layout and can be used to study how Book of Santa handles regular wins, Free Games, and the special symbol mechanics before playing for real money.
