Book of Santa delivers a solid 96.05% return to player in base game mode. With the Bonus Pop buy feature active, RTP ranges from 94.73% to 95.98% depending on your symbol selection. The Risk Game gamble feature operates separately at an average 84% RTP.
Land 3 Book Scatters anywhere to trigger 10 free spins. Before the round begins, one symbol is randomly selected to expand vertically across entire reels. When enough expanding symbols land to form a win, they fill their reels and pay on enabled paylines regardless of position. Free games can retrigger during the feature.
After any base game win, gamble your prize by picking a card to beat the dealer's card. Win and your prize doubles. Draw and you get another chance. Lose and forfeit everything. Play up to 10 consecutive rounds. The Joker beats all cards, but the dealer never gets one. RTP varies from 42% (against Ace) to 162% (against 2).
Skip the wait and buy instant access to free games. Click the Bonus Pop button to choose which symbol expands during your purchased round.

Click the glowing START button to spin the 5 reels with 3 rows each. Matching symbols must land on enabled paylines starting from the leftmost reel in adjacent positions to win, except for Scatter symbols which pay anywhere.
Hit 3 or more Book symbols anywhere to trigger 10 free spins with a randomly selected expanding symbol. When enough of the special symbol land to form a win, they expand vertically and pay in both adjacent and non-adjacent positions on active lines.
After any base game win, you may risk your prize in the card-picking gamble feature. Beat the dealer's card to double your winnings up to 10 times. Or press TAKE WIN to collect safely. Winnings from Bonus Pop purchases cannot be gambled.
Book of Santa nails the classic expanding-symbol mechanic with a festive twist. The 96.05% RTP is honest, the Bonus Pop feature gives impatient players control over which symbol expands, and the Risk Game gamble adds genuine decision-making with transparent odds. Endorphina's math is solid here—the 162% RTP when the dealer shows a 2 versus 42% against an Ace creates real strategic depth.
The base game RTP is 96.05%. When using the Bonus Pop buy feature, RTP ranges from 94.73% to 95.98% depending on which symbol you select to expand. The Risk Game gamble feature operates at a separate average RTP of 84%, which varies from 42% to 162% based on the dealer's revealed card.
At the start of your 10 free spins, one symbol is randomly chosen to expand. When enough of that special symbol land to complete a winning combination (regardless of position), they expand vertically to fill their entire reels. These expanded symbols then pay for combinations on enabled paylines even in non-adjacent positions, potentially creating massive line wins.
Yes, but only through the Bonus Pop buy feature. Click the Bonus Pop button in the bottom-left during base game to purchase instant free games and select your preferred expanding symbol. The cost starts at €6.90 for a €0.10 bet and scales proportionally. Regular free games triggered by 3+ Scatters assign a random expanding symbol.
Santa Claus is the highest-paying regular symbol at €50.00 for five of a kind on a €0.10 bet (500x multiplier). The Book Scatter/Wild pays €20.00 for five (200x). Maximum potential comes from landing multiple expanded symbol combinations during free games, especially if you retrigger additional free spins within the feature.
That depends on the dealer's card and your risk tolerance. The gamble offers positive expected value (over 100% RTP) when the dealer shows a 2, 3, 4, 5, 6, 7, or 8. It's negative EV against 9, 10, J, Q, K, and especially A (42% RTP). Smart strategy means gambling only when you have mathematical advantage, and always taking your win when the dealer shows face cards or Aces.
