Bonus Features: How to Win Really Big
Main Bonus: Free Spins
How to activate:
- Get 3 or more Book symbols in any positions
- Instant payout: 2×, 20×, or 200× for 3, 4, or 5 Books
- 10 Free Spins as a gift!
How it works:
Before the round starts, a special symbol is randomly selected. The Free Spins round with Expanding Symbol is the main bonus round that most players spin the reels for.
- To trigger it, you need to land three or more Book of Santa symbols anywhere on the reels. This simultaneously awards a Scatter win.

- Before the round begins, the Book magically opens and randomly selects one of the regular symbols (e.g., Santa, the bell, or the star). This symbol becomes the special expanding symbol.

3. If during the free spins a sufficient number of special symbols land to form a winning combination, this symbol expands to cover the entire vertical reel, covering all three positions. This multiplies the chances of getting high-paying combinations, especially if the Santa symbol expands.

4. Importantly, the free spins round can be retriggered if 3 or more Book Scatter symbols land again, making this bonus potentially endless and very profitable.
Risk Game: For the Boldest
After any win, you can try to double it:
- Guess the card color (red/black)
- Correct guess – double your win
- Wrong guess – lose the win
- You can risk several times in a row!
Conclusion
“Book of Santa” from Endorphina is a quintessential representative of the “book” slot genre, wrapped in impeccable Christmas packaging. It combines gameplay familiar and loved by millions, a magical holiday atmosphere, and an enviable win potential of up to 5,000x the stake. Simple yet effective bonus features, especially the free spins round with the expanding symbol, keep the player in suspense and offer hope for a big jackpot.
This slot has already become for many as integral a part of the New Year holidays as the Christmas tree or tangerines. It gives not only excitement but also that very feeling of miracle that everyone awaits at the end of December.
