A Christmas Coat on a Classic Book Engine
The theme is the main thing that separates this release from its siblings. The reels are dressed in festive imagery — wintry royals sit alongside seasonal icons, and the soundtrack leans on soft, chiming melodies rather than the adventure-tomb atmosphere of the original book format. Underneath that holiday paint, the feature set is the same proven loop Spinomenal reuses across the line, which makes the game an easy pick-up for returning players.
The Book Is Both Wild and Scatter
The defining symbol is the Book itself, which performs two jobs at once. It acts as a wild, standing in for the regular paying symbols to help complete combinations across the grid. It also acts as the scatter that opens the bonus. Because one symbol carries both roles, every Book that lands matters twice over — it can rescue a marginal spin in the base game and simultaneously push you closer to the Free Spins trigger.
How the Free Spins Round Triggers
Land three or more Book scatters anywhere on the reels and the Free Spins feature begins. This is the heart of the game; in a high-volatility title like this one, the base game is largely a means of reaching the bonus rather than a reliable source of payouts on its own. The trigger is the moment the session really starts to matter.
The Special Expanding Symbol Explained
Before the free spins play out, one of the regular symbols is selected at random to become the Special Expanding Symbol for that round. During the spins, whenever that chosen symbol lands as part of a winning combination, it expands to cover its entire reel and pays according to the paytable for every position it fills. If the same symbol expands across several reels in one spin, large stretches of the grid can pay at once. Because the expanding symbol is re-rolled every time you enter the bonus, no two Free Spins rounds feel quite the same — a low-value symbol expanding produces modest returns, while a premium symbol filling multiple reels is where the standout wins come from.
Retriggers Keep the Round Alive
The bonus is not necessarily a one-and-done affair. Landing another three or more Book scatters during the Free Spins awards a fresh batch of spins, and crucially the same expanding symbol stays in play. A lucky retrigger on a round where a high-paying symbol has been selected is the scenario every player is chasing, since it stacks more chances for that symbol to fill the reels.
What High Volatility Means for Your Session
Spinomenal classifies Book Of Xmas Reloaded as a high-volatility slot, and that label shapes how you should approach it. Expect stretches where the base game runs cold, punctuated by the bigger swings that only the bonus can deliver. The sensible way to play is to budget for several attempts at reaching the Free Spins rather than expecting steady returns from regular spins.
Try the Free Demo First
Because so much of this slot's character lives inside one feature, the demo is useful rather than a formality. Playing for free lets you feel how long the base game tends to run between triggers, watch how often a high-value symbol gets selected to expand, and decide whether the stop-start rhythm of a high-volatility book slot suits you — all.

If the expanding-symbol formula appeals, Spinomenal has built an entire shelf of variations on it. Book Of Champions Reloaded applies the same reloaded treatment to a competitive theme, Book Of Skulls takes the format somewhere darker, and Book Of Alice offers a storybook twist on the core loop.
