About Game

Demo Overview

In the Book of Santa demo, the Free Games start by picking a random symbol to expand, and you play with whatever it lands on. The badge beside reel 1 changes that. A tilted red-and-gold book graphic reads BONUS POP, and through it you can buy the round and choose the expanding symbol yourself.

This 5-reel slot is Endorphina’s December 2019 Christmas release, and the reels are set inside a brick fireplace opening. Purple-blue stone bricks are lit orange-red, embers glow along the bottom ledge, and red-and-white candy-cane stripes divide the reels. Santa is a square picture tile, smiling and white-bearded in a red hat and small round gold-rimmed glasses, which puts the game among the Santa slots as firmly as among the book games. The logo puts a red Christmas bauble in the ‘o’ of ‘of’, and the sleigh is blue with gold swirls and gold runners, with no reindeer in sight.

Slot Features

The Book

Book of Santa win with a gold-framed book on reel 2 and a bell on reel 1 joined by a candy-cane payline
A book on top of reel 2 stands in beside the bell on reel 1, both framed in gold, and the candy-cane line through them pays 0.5x.

The brown leather-bound book with gold corner fittings, drawn on a red square tile with white snowflake marks, does two jobs. As the scatter, it counts at any position and pays 2x, 20x, and 200x for three, four, and five, and 3 or more of them start the Free Games. As the Wild, it substitutes for Santa, the bell, the star, the sleigh, and the five card ranks on a line.

Expanding Symbol

Each round of Free Games has one special expanding symbol. It expands if enough of it are on the reels to complete a winning combination, and where they land doesn’t matter, only how many. The expansion is vertical and comes after the payout of regular symbols, and the expanded symbol then pays in adjacent and non-adjacent positions, only on enabled paylines.

The book can’t help with that count. During Free Games, the Wild cannot substitute for the special expanding symbol, so the symbol has to land in enough places by itself.

Free Games

Book of Santa grid with Santa tiles on reels 1 and 3, a sleigh on reel 2, a book on reel 4 and a star on reel 5
Two Santa tiles land apart, top of reel 1 and middle of reel 3, beside a sleigh on reel 2, a book on reel 4 and a star bottom right, with no win lit up.

3 or more books trigger 10 Free Games with a special expanding symbol. How the symbol is picked depends on how you got there.

Start Expanding symbol What it can do
3 or more books land A random symbol is selected Expands if enough are on the reels for a win, wherever they land
Bought with Bonus Pop The symbol you chose, guaranteed The same, as the bought round works like a triggered one
Either way, the symbol expands after the payout of regular symbols.

The round can be won again during the feature, so books landing within it can add more Free Games.

Bonus Pop

Bonus Pop lets you select any symbol to give the capacity to expand, and it buys the Free Games at any time. The cost depends on the total bet as well as on the chosen option. A bought round opens with one main-game spin that lands 3 books, and the selection step that follows is guaranteed to give you the symbol you chose. Past that step, the bought round works the same way as one triggered by chance.

A win from a regular spin, though not from a bought round, can also go to the Risk Game, the card gamble behind Crown Coins’ odds screen; if the Dealer wins in any round, you lose your winnings and the Risk Game ends.

Take Bonus Pop away, and Book of Santa is a familiar 10-line book slot in a fireplace frame. The choice is what lifts it, because Santa pays 500x for five on a line while Q, J, and 10 pay 10x. The limit is everything around that choice. The Wild can’t help the expanding symbol, a triggered round still leaves the pick to chance, and there’s little else to explore in free play once you’ve seen the expansion work.

How to Play

The Book in the Exception

Nine of the ten symbols in Book of Santa need to line up on enabled paylines across adjacent reels from the leftmost one before they pay; the book is the exception. All prizes are for combinations of a kind, and each enabled line pays its highest combination only. Free Games keep the same bet and lines as the game that started them.

The book plays by its own rules because it has two roles. As the scatter, it counts anywhere on the reels, and its scatter win joins any line wins on the same spin. As the Wild, it completes line wins for every other symbol in the regular game.

The Free Games change one thing about the pay rule. Once the special symbol expands, it pays in adjacent and non-adjacent positions, so a gap between reels no longer breaks the win, as long as it’s on enabled paylines.

RTP and Bet Values

Stakes run from €0.10 to €45 a spin. The demo shows an RTP of 98.05%, and that figure excludes the Risk Game. Endorphina lists 96.05%.

Demo Game Paytable

Only the four picture symbols pay with just two on a line, and the sleigh pays exactly what the star does. A and K pay 15x for five, a step above Q, J, and 10 at 10x. All values are x the total bet, and the book row shows its scatter pay, counted in any position.

Frequently Asked Questions

With Bonus Pop, yes. Buying the Free Games lets you select any symbol to expand, the selection step is guaranteed to give you that symbol, and the cost depends on the total bet and the option chosen. A round started by 3 or more books picks a random symbol instead.
During Free Games, the Wild cannot substitute for the special expanding symbol. The expansion needs enough of that symbol itself on the reels to complete a winning combination, in any positions.
It expands once enough of it are on the reels to complete a winning combination, wherever they land, because only the number matters. The expansion comes after regular symbols have paid, and the expanded symbol then pays on enabled paylines in adjacent and non-adjacent positions.
Four pictures do in Book of Santa. Santa pays 1x for two, and the bell, the star, and the sleigh pay 0.5x each, while A, K, Q, J, and 10 start paying at three.
Free Games can be won again during the feature, so 3 or more books within the round can add more. They keep the bet and lines of the Book of Santa spin that started them.
