Theme: Christmas, Santa and a magic book
Book of Santa swaps the deserts and tombs we are used to in book slots for a winter landscape full of snow. Presents, candles, bells, Santa himself and above all the magic book spin across the reels.
The colours are warm and festive, with red, gold and a cool blue in the background. The music recalls a set of chimes and conjures the calm atmosphere of Christmas Eve. Even the small animations, such as falling snowflakes and flickering candles, fill out the seasonal feeling.
Endorphina has taken a recipe proven over the years and given it a clear seasonal hook. The combination of a familiar game and festive dress works surprisingly well. Even outside December the title feels pleasant and a little nostalgic.
How Book of Santa plays
The slot has five reels, three rows and ten paylines, which are usually fixed. You choose your stake through the coin value and the level, which together set the total amount per spin.
After the spin, matching symbols are evaluated from left to right on the active lines. The book plays a double role here, which we come to in the next part of the review.
If you want to be sure of the rules, start with the demo first. That way you will see how often the book lands and what rhythm the game offers before you put your own money in.
The book mechanic, expanding symbol and gamble
The heart of the game is the book, which works as wild and scatter at the same time. Three or more books start ten free spins, into which the game picks one special symbol.
That chosen symbol expands across the whole reel during the free spins if it lands in the right place. It is precisely this expansion that can fill the screen and produce the biggest wins of the whole game.
After an ordinary win you can try the gamble feature, guessing the colour of a hidden card to double the amount. It is a purely optional risk and one worth using in moderation.
RTP, volatility and verified parameters
Book of Santa is one of the highly volatile slots, which is typical of book games. According to Endorphina the return sits around 96 %, so at the standard level for this type of game.
High variance means less frequent but potentially more substantial wins, above all during the symbol expansion. The table below sums up the key figures together with the verification date.
| Slot | Provider | RTP | Volatility | Mechanics | Source | Verification date |
|---|---|---|---|---|---|---|
| Book of Santa | Endorphina | ~96 % per the provider | high | book mechanic (expanding symbol), free spins, gamble | Endorphina | 2026-09-15 |
The figures are indicative, since an operator may deploy a version with a different return. Our volatility guide explains how to work with this kind of data.
Who Book of Santa is for
The game fits a player who likes book slots and does not mind higher risk. Anyone who favours a festive touch and a tense symbol expansion will be satisfied.
High volatility calls for patience and a sensible budget, because runs without a win can be longer. That is exactly why it pays to choose smaller stakes and play for longer, so that you last until the free spins start. More cautious players might consider a calmer title, for example Satoshi's Secret with its medium volatility.
If, on the contrary, you are expressly after adrenaline, browse the whole high volatility slots section and compare similar games.
