Book Of SpinOWeen Slot Review
Twisted rope and gilt frame the reels, straw broomsticks cross the corners, and small pumpkins sit at the foot of the title banner on a violet Halloween night. Spinomenal’s Book Of SpinOWeen is better built than a seasonal slot needs to be: this is a full book game in costume, and the twist worth arguing about is that it re-picks its expanding symbol on every single free spin instead of fixing one for the round.
It runs on a 5×4 grid with 10 fixed paylines and an RTP of 96.01%, and its wild doubles as the scatter, so one symbol handles the substituting, the paying and the triggering. It sits alongside titles like Spooky Halloween – Hold & Hit 3×3 and Lilith Awakens in a catalogue that keeps seasonal themes in steady rotation.
The Base Game and the Paytable
All symbols pay left to right from the leftmost reel, and only the highest win on each line is paid. Wins on multiple lines in the same round are added together into the total for that round, and each win is multiplied by the bet per line. The full list of combinations and payouts is in the paytable.
The reel set is deep violet against a murky brown-orange backdrop with dark silhouettes lingering at the edges. The artwork stays glossy and gaudy throughout, and the twisted rope-and-gold borders with bead-like finials keep the frame as decorated as the symbols inside it.
The wild is a chest with a spider inside, and it does double duty. It substitutes for every symbol in the game, and it’s also the scatter, so one symbol handles the substituting, the paying and the triggering. Land three or more anywhere on the reels and it pays on top of any line wins while starting the free spins round:
- 3 scattered wilds: 2x the bet, plus 10 free spins
- 4 scattered wilds: 25x the bet, plus 10 free spins
- 5 scattered wilds: 250x the bet, plus 10 free spins
- 6 scattered wilds: 500x the bet, plus 10 free spins
The regular symbols pay as multiples of the total bet:
- Witch Hat: 100x for two, 1,000x for three, 10,000x for four, 50,000x for five, 100,000x for six
- Crowned Skull: 50x for two, 400x for three, 4,000x for four, 20,000x for five, 40,000x for six
- Pumpkin / Potion Bottle: 50x for two, 300x for three, 1,000x for four, 7,500x for five, 15,000x for six
- A / K: 50x for three, 400x for four, 1,500x for five, 3,000x for six
- Q / J / 10: 50x for three, 250x for four, 1,000x for five, 2,000x for six
Those are hefty numbers at the top of the ladder, but they sit in a six-column paytable on a five-reel game, so the top tiers are doing a lot of the advertising. The royals pay modestly and keep the balance ticking between feature hits.
Controls, Autoplay and Turbo
Bet per line is set with the plus and minus buttons, and the spin button or the space bar starts the reels. Every win in a round is displayed in the win field, and the help and settings buttons are disabled while a spin is in progress.
Beyond that, the control set is standard, with a couple of conveniences worth knowing:
- Autoplay: continuous play at the selected bet per line, configurable by number of spins and stopped with the pause button
- Turbo Mode: the shortest possible game round, toggled by the rabbit button on desktop or through the settings menu on mobile, and available from the autoplay configuration screen too
- Bet lock in free spins: the plus and minus buttons are disabled while the round plays out, so the triggering bet carries through
Free Spins and the Expanding Symbol
Three or more scattered wilds award 10 free spins, with the bet per line carried over from the round that triggered them. Scatter prizes are paid in addition to any regular line winnings, so the trigger itself can be a decent result before a single free spin has played out.
How the Expanding Symbol Works
Every free spin gets its own randomly chosen expanding symbol, which can be any symbol in the game apart from the scatter wild, and the assignment lasts for that spin only. Once the spin’s result is settled, that symbol stretches to cover the reels and forms new paylines on top of the existing ones.
The expansion only happens if it produces a win. When it does, the expanded symbol pays its paytable value on every active line, and it doesn’t matter whether the winning symbols sit on consecutive reels.
Expanded symbols count separately from the original result, which is what allows a single spin to pay twice: once for the combinations as they landed, and again for what the expansion created. A spin where the Witch Hat is drawn as the expander and a few already sit on the reels is where the big multiples live.
Retriggers and the Ceiling
Free spins can retrigger, and each retrigger adds another 10 spins to the counter. There’s no stated limit on how many times this can happen within a round.
As for the ceiling, the game’s own biggest number is the paytable’s top rung: 100,000x the total bet for six Witch Hats, with the scatter wild’s 500x sitting far below it. The six-of-a-kind column is the stretch, given five reels, so the realistic upper reaches are built from expanded symbols stacking line wins on a single spin.
Buy Feature
A Buy Feature button sits alongside the regular controls, and it does exactly what it says: it purchases an immediate free spins round. Clicking it opens a window where you set the bet the round will play at, and the buy price adjusts to match that bet.
It’s a straightforward shortcut for anyone who doesn’t want to wait on the scatter wilds to line up. The triggering bet carries into the round, and the free spins play out with the same expanding symbol mechanic, retrigger rules and paytable as a naturally triggered round, so nothing about the feature changes apart from how you got there.
Our Honest Verdict
Overall Rating: 7.7/10
Playing this is playing a book-slot with its Halloween costume on properly, and the reason to choose it over the shelf of other book games is that no two of its free spins are ever the same round. Ten spins can feel like ten different features, because the expander is redrawn every time.
That re-roll is the strength, and it’s a real one: the round never settles into the fixed script the book formula usually runs. The weakness is the paytable’s top rung, a six-of-a-kind prize the five-reel grid can’t actually deal, so the advertised ceiling is thinner than it looks.
It’s a confident, well-dressed take on a familiar formula, and it rewards anyone who already likes book games and wants theirs with cobwebs on. Anyone hoping for a new shape of slot won’t find one here, and that’s fine: the cottage is cosy, the broomsticks are crossed, and the book opens the way a book should.
