Book of SpinOWeen

Book of SpinOWeen Overview

Book of SpinOWeen is a Halloween book slot from Spinomenal, released on 16 October 2023. It uses a wider grid than the classic book formula – six reels and three rows – with 10 fixed paylines, stakes from 0.10 to 100 per spin, an RTP of 96.01% and a maximum win of 10,000x the bet.

A Haunted Fairground

The reels stand in a purple night scene framed by striped poles, with a witch’s broom leaning on each side. The premium symbols are Halloween props – a carved pumpkin, a pointed witch’s hat with a crescent moon, a spider on a spell book and a skull potion bottle – and the lower tier is the usual card set from 10 to A.

The Paytable

The game’s own configuration lists every payout as a multiple of the line bet, and the sixth reel adds a step that five-reel book slots do not have:

• 10, J, Q: 5 / 25 / 100 / 200 for three to six.
• K and A: 5 / 40 / 150 / 300.
• Two mid premiums: 5 for two, then 30 / 100 / 750 / 1,500.
• Second-best premium: 5 / 40 / 400 / 2,000 / 4,000 for two to six.
• Top premium: 10 / 100 / 1,000 / 5,000 / 10,000.

Our base-game screenshot confirms the scale: at 10 per line (a total bet of 100) four Js on one line paid 250 – exactly 25 times the line bet.

Bet Settings

All ten lines are always active, so the only choice is the stake per line, set with the PER LINE control at the bottom left. The total bet is simply ten times that figure: our screenshots show 2 per line for a total of 20 and 10 per line for a total of 100. The published range of 0.10 to 100 per spin therefore works out to 0.01 to 10 per line. Autoplay and a turbo mode sit next to the spin button, and a separate BUY button opens the feature purchase.

The Spell Book

The book with the spider on its cover works in the familiar way: it is the wild and the scatter at the same time, and enough of them anywhere on the reels open the bonus. The paytable also gives the books their own scatter awards of 2, 25, 250 and 500 for three to six.

Free Spins With a New Symbol Every Spin

The trigger screen confirmed 10 free spins, and its small print explains the twist: “On each individual spin, a randomly assigned symbol will act as the expanding symbol for that spin only.” Classic book games pick one symbol for the whole round; here the choice is redrawn every spin, and the current symbol is shown in the box above the top-right corner of the reels.

When the chosen symbol lands on enough reels, it grows to fill them and pays on all ten lines, even if the reels are not next to each other.

How Our Free Spins Went

We played the round at a total bet of 20 (2 per line):

• With 9 spins left, A was the symbol of the spin. It expanded on three reels and paid 100.
• With 2 spins left, A came up again and this time filled five of the six reels. The game called it an Epic Win of 3,010 – about 150x the bet – and the round stood at 3,520 (176x).

The paytable explains that number: five As pay 150 times the line bet, and a full reel pays on all ten lines, so 150 × 2 × 10 = 3,000, plus a small extra win on the same spin.

Buying the Feature

The Buy Feature panel sells the round directly: “Trigger 10 free spins with a random expanding symbol”. At a bet of 20 the price was 2,120, which is 106x the bet – the same figure the game’s configuration gives. Our naturally triggered round returned 3,520, so this time the purchase would have paid off, but the result depends heavily on which symbols are drawn.

Where the 10,000x Comes From

The cap is not an arbitrary number. Six top premiums on one line pay 10,000 times the line bet, and with an expanding symbol covering all six reels the same win lands on all ten lines at once – 10,000 times the total bet. The celebration levels start at 7x (Big Win) and climb through 12x and 25x to 40x (Epic Win).

The Same Engine as Other Spinomenal Books

Book of SpinOWeen shares its maths model with Book of Rebirth – Extreme, Book of Demi Gods VI and Book of Fairytale Beauties: six reels, ten lines, a 106x buy and a 10,000x maximum. The difference is the theme.

RTP and Volatility

SlotCatalog lists the RTP as 96.01% but marks the game with RTP ranges, so your casino may run a different version. No volatility rating is published.

Who It Is For

Book of SpinOWeen suits players who like the book format but want more action in the free spins. Because the expanding symbol changes every spin, a round never hangs on one lucky draw, and the sixth reel lifts both the line pays and the ceiling.
