Book Of Xmas Jingle Bells Slot Review
Sleigh bells on the corners, holly on the title plaque and a candy-cane frame against a deep blue winter night: Book Of Xmas Jingle Bells wears its Christmas wrapping with real conviction. The engine underneath is less familiar than it first appears, because rather than locking one special symbol in for the whole bonus round, this game re-picks it on every single free spin, which turns ten spins into ten separate draws.
It runs on a 6×3 grid with 10 paylines and an RTP of 96.01%. Spinomenal have mined this vein before, in Book Of SpinOWeen, Book Of Elves 2 and Holidays Joker Xmas, and this is their tinsel-draped entry. It’s a Christmas slot that knows precisely what it is.
Symbols, Paylines and the Book
All symbols pay left to right from the leftmost reel, and only the highest win on each line is paid. Wins are multiplied by the bet per line. You adjust stakes with the plus and minus buttons, which set the bet per line; during free spins those buttons are disabled, since the round continues at the triggering bet.
Spinning is a one-button affair. The spin button or the space bar sets the reels going, and all wins in a round land in the win field as they’re confirmed. Help and settings lock up mid-spin, so there’s no adjusting anything while the reels are moving. It’s a slot built for steady, uninterrupted play rather than constant tinkering.
With 10 lines across six reels, there’s room for six-of-a-kind combinations that smaller grids can’t offer. The three premium symbols pay from two-of-a-kind, which softens the wait between wins. The royals need three.
The paytable, in multiples of the total bet:
- Santa with lantern – 100x, 1,000x, 10,000x, 50,000x, 100,000x for two to six
- Snowman – 50x, 400x, 4,000x, 20,000x, 40,000x for two to six
- Deer / Cup and gift – 50x, 300x, 1,000x, 7,500x, 15,000x for two to six
- A / K – 50x, 400x, 1,500x, 3,000x for three to six
- Q / J / 10 – 50x, 250x, 1,000x, 2,000x for three to six
The Book of Xmas itself is the wild, and it counts as any symbol. It’s also the scatter, which makes it the symbol the whole game turns on. Land it three or more times anywhere on the slot and it pays on top of any line wins:
- 3 Books – pays 2x the bet and triggers 10 free spins
- 4 Books – pays 25x the bet and triggers 10 free spins
- 5 Books – pays 250x the bet and triggers 10 free spins
- 6 Books – pays 500x the bet and triggers 10 free spins
Those scatter prizes are paid in addition to regular payline winnings, so a triggering spin can pay twice over: once for the Books themselves and once for whatever lines they helped complete as wilds. On a 6×3 grid, six scattered Books is a genuinely reachable outcome rather than a decoration on the paytable.
The gap across that ladder is enormous, and it’s steeply weighted towards the top end. The real prize for landing Books is the round itself; the scatter cash is a warm-up.
Free Spins and the Expanding Symbol
Three or more scattered Books trigger 10 free spins. The bet per line stays the same as in the game that triggered the round. Free spins can re-trigger, awarding another 10 spins on top of whatever is left, so a lucky round can run well past its original length.
How the Expanding Symbol Works
Every free spin assigns one symbol at random, and everything except the Book is eligible. That symbol acts as the expanding symbol for that spin only. Once the spin’s result is determined, it stretches to form new paylines on top of the existing ones, but only where the expansion actually creates a win.
The expanded symbol pays its full value across all active lines, and the winning symbols don’t need to sit consecutively. Expanded symbols count separately from the original result, so a single spin can pay the base combination and then pay again once the expansion lands.
Run one spin from start to finish and the order of events matters. First the reels stop and any base line wins are settled. Then the assigned symbol expands, if expanding helps. Finally the expanded wins are added on their own.
Two payouts from one result, both at the triggering bet, and nothing carried over to the next spin except the spin counter. Because the assigned symbol changes every spin rather than being locked in for the round, each free spin carries its own small lottery. An expanding Santa over a board already carrying a few of him is the outcome the whole round is built around; an expanding 10 is the one it shrugs off.
The round keeps its own rhythm for another reason: the controls lock down while it runs. The bet buttons are disabled until the free spins finish, so the pace is entirely in the game’s hands. Every win in a round is totted up in the win field as it lands.
The top of the ladder is a full line of six Santas at 100,000x the total bet, before the expanding symbol adds anything on top.
Our Honest Verdict
Overall Rating: 7.1/10
This is a book slot in a Christmas jumper, and the simplicity is the whole point of choosing it: ten lines, one all-purpose Book, and a festive skin done with more care than most. Anyone after that combination will feel at home here before the first spin settles.
The bonus round is its real strength. Re-rolling the expanding symbol every spin means no two free spins play the same way, and because expanded wins pay separately from the base result, a good board pays twice.
That same re-roll is also the weakness: the round never builds towards anything, and a whole bonus can pass without a premium symbol ever getting its turn. It’s for players who like the classic book formula and want it wrapped in tinsel rather than reinvented. Anyone after modern extras won’t find them under the tree here. For a fireside December session with a familiar engine, though, it’s easy company.
