Book of Santa is a 2020 BGaming slot that adapts the established book-mechanic format to a Christmas theme, and does so with more conviction than most seasonal variants of the genre. The expanding symbol mechanic — borrowed from the Book of Ra family — pairs naturally with festive imagery, and BGaming reinforces it with an RTP of 97% that makes this one of the most player-favorable titles in the entire batch.

The game plays on a 5-reel, 10-payline grid with bets from $0.10 to $200 per spin. The fantasy-coded Christmas theme fills the reels with Santa, gift boxes, reindeer, Christmas trees, and seasonal playing card suits. The visual presentation is warm and polished for a 2020 BGaming release, and the expanded bet ceiling of $200 maximum gives high-stakes players more room than many of BGaming’s standard titles.

The core mechanic mirrors the book format: during the free spins round, one symbol is selected randomly to become the expanding symbol. When that symbol lands on any reel during the feature, it expands to fill the entire reel, paying across all lines regardless of where it sits. Santa symbols act as both wild and expanding candidate — when Santa is chosen and lands during free spins, the gift multiplier wild element adds an additional layer of value to the expansion payouts.

Book of Santa carries a 97% RTP and high volatility — an unusual combination that makes it highly attractive on a mathematical basis. The high volatility means sessions are still unpredictable, but the 97% return rate is genuinely exceptional for a non-specialist slot. The max win potential reaches 5,000x your stake. No bonus buy is available.

Book of Santa is an excellent choice for book-mechanic fans who want the best possible RTP combination with the format. The 97% return rate and 5,000x ceiling make this one of the strongest value propositions in the BGaming catalogue.
