Book of Xmas 3 is the third festive chapter in Spinomenal's Christmas book series, and it arrives with a clear sense of occasion. The cover star is a golden spellbook wrapped in candy-cane trim, red ribbons and jingle bells, with a glowing ice-blue snowflake set into its face. Behind it, a dark winter forest of snow-heavy pines is lit by drifting coloured lights, so the whole scene feels like a quiet December night rather than a busy shopping-mall Christmas. The title sits on a carved wooden plaque topped with holly, a small touch that gives the presentation a warm, handmade feel. Spinomenal's art team is known for polished, glossy symbols, and this release keeps that standard, with crisp festive icons and a soft, twinkling soundtrack that stays in the background.
The layout is slightly wider than most book slots. Instead of the usual five columns, the game spins 6 reels with 3 rows and 10 fixed paylines, which gives each spin an extra column of symbols to work with. The pace is calm in the base game and much more intense when the book opens up its bonus round. The extra reel matters here, because the series' signature feature has more room to cover the screen when it kicks in. We will look at the mechanics in detail further down.
This sequel suits players who already know the classic book format and want a seasonal version with a bit more room on the grid. It also fits those who like a simple ruleset with a high ceiling, since the game is built around one big feature rather than a long list of side modifiers. If you enjoy winter themes with a touch of magic, keep reading for the features, the maths and what a typical session looks like.
Book of Xmas 3 follows the familiar rules of the series and keeps them easy to read. Wins form left to right across 10 fixed paylines on a 6x3 grid, and the paytable is split between festive high-value symbols and lower card ranks dressed in winter colours. The golden snowflake book is the key icon: it acts as both the wild and the scatter, so it can complete line wins on its own and also open the bonus round when enough copies land anywhere on the reels.
Landing three or more books starts the free spins. Before the round begins, one symbol is picked as the special expanding symbol. Whenever that symbol lands during the free spins, it can grow to fill its entire reel and pay across all lines, even if the matching symbols are not on adjacent reels. On a six-reel grid this is where the game shows its strength, as a high-paying expanding symbol across several columns can produce wins far above the base game level.
The base game itself is quiet. Most spins return small hits from the card symbols, and the anticipation builds mainly when two books land early and the reels slow down for the third. This is a slot built around one feature, so the overall rhythm is a steady wait followed by short bursts of action.
The theoretical return is 96.01%, slightly above the usual market benchmark of about 96%. That figure is calculated over a very large number of spins, and in this game a large part of it is concentrated in the free spins. As a result, the experience in a normal session depends heavily on how often the bonus appears and which symbol gets chosen to expand.
Volatility is high. In practice this means longer spells of small or no wins, then occasional large results when the feature lines up well. It is not a slot for players who want a constant drip of medium wins, and a bankroll that covers a good number of spins is helpful if the aim is to see the bonus a few times.
The top prize is capped at 10,000x the stake, which equals 1,000,000 at the maximum bet of 100. Bets start at 0.10, so the game works for low stakes as well. There is no jackpot, progressive or fixed, so every big result comes from the line wins and the expanding symbol. Taken together, the numbers describe a classic high-risk book slot with a fair RTP and a large ceiling, presented in a festive wrapper.
Got the expanding symbol on the premium during free spins and four reels lit up at once. The sixth reel really makes a difference compared to the older Book of Xmas games.
Lovely winter look, the snowflake book and the forest background are very well done. The base game is slow though, so you need some patience for the scatters.
Classic book mechanic with a festive skin and 10,000x on top. Retriggered the bonus once and the session turned around nicely.
Plays smoothly on my phone in short sessions. Dead spins come in streaks, which is expected with high volatility, but the bonus rewards the wait.
RTP of 96.01% is fair for a book slot. I like that the rules are simple and you always know what you are waiting for.
Tried it in demo first and then for small stakes. The jingle-bell sounds are nice, though the music repeats a bit during longer play.
