Book Of Horror - Friday the 13th

Spinomenal's Book of Horror: Friday the 13th borrows the horror series premise and pushes the max win ceiling to 10,000x, placing it among the more ambitious entries in the Book of Horror franchise. The 5x3 grid keeps 10 paylines but narrows to 5 fixed lines, with high volatility and a 96.18% RTP. The buy feature costs 104x your bet for guaranteed access to 10 free spins with an Expanding Symbol, and the witch symbol tops the paytable with a single-payline payout capable of reaching the 10,000x mark. Available on desktop and mobile at Wild.io across BTC, ETH, USDT, and the full crypto range.

What is Book Of Horror - Friday the 13th?

Book of Horror: Friday the 13th is a 5x3 video slot from Spinomenal with a 96.18% RTP, high volatility, and 5 fixed paylines. The Book of Horror symbol acts as both Wild and Scatter, triggering 10 free spins with an Expanding Symbol when three or more land anywhere on the reels. The witch symbol pays up to 10,000x the bet for five on a payline.

The expanded max win versus the original Book of Horror comes from the same core mechanic but with a higher-paying witch symbol capping the paytable. Three or more book scatters trigger free spins with an expanding symbol chosen at the start; if the witch is selected and fills multiple adjacent reels during a high-bet spin, the 10,000x ceiling is reachable. The bonus buy at 104x the current bet lets players enter the feature immediately.

Head to Wild.io and create a free account to start playing Book Of Horror - Friday the 13th.

1. Set your stake using the bet controls, the 5-payline structure means the total bet covers fewer lines than a standard 10-payline game.
2. Use the buy feature at 104x your bet to enter free spins directly, or spin the base game and wait for three or more Book of Horror symbols to appear anywhere on screen.
3. On triggering free spins, a wheel appears and selects one regular symbol as the Expanding Special for all 10 spins.
4. During the feature, the chosen symbol stretches to fill its entire reel on every spin where it forms a winning combination.
5. The witch at the top of the paytable is the most valuable expander: a full-reel stretch across multiple columns simultaneously generates the largest payouts.
6. Three or more book scatters during free spins retrigger the round with 10 additional spins.

Book Of Horror - Friday the 13th Slot Theme & Graphics

The Friday the 13th branding reworks the original Book of Horror's Halloween graveyard into something closer to the slasher-film genre. The backdrop references the eerie camp-lake setting associated with the franchise, with fog across still water and a moonlit treeline behind the reels. The symbols carry a similar horror palette to the first game but with redesigned artwork, the witch's robes shift colour, the cauldron bubbles with a different chemical green, and the tombstone bears updated inscription details.

Spinomenal threads the Friday the 13th atmosphere into the audio design as well, replacing the general Halloween ambient track with something closer to a film score: low strings, sudden stings on wins, and silence between spins that builds mild tension. On mobile, the portrait layout works identically to the base game, and the buy-feature button stays accessible from the main controls panel without needing a separate menu.

Book Of Horror - Friday the 13th Slot Symbols & Paytables

Book of Horror: Friday the 13th shares its symbol structure with the parent series but recalibrates the paytable to support the higher 10,000x ceiling.

Low Value Symbols

The low-value symbols are the standard playing card ranks: Ace, King, Queen, Jack, and 10. These land frequently across the 5 paylines and represent the bulk of base-game returns. Their individual pay multipliers are the smallest in the game, but the 20.4% hit frequency means small card-rank wins punctuate regular sessions. During free spins, a card-rank selected as the Expanding Special can still stretch to cover full reels, and across a 5-payline game, even a low symbol's full-reel expansion pays a visible amount at higher bet levels.

High Value Symbols

The premium symbols are the Witch, Green Potion Bottle, Cauldron, and Tombstone. The witch tops the paytable at up to 10,000x the total bet for five on a payline, this is also the game's maximum win and it requires the witch to be both selected as the expanding symbol and to fill multiple adjacent reels during a single free-spins spin. The green potion bottle and cauldron follow in descending pay order, with the tombstone as the lowest-paying premium. Each symbol carries detailed artwork consistent with the Friday the 13th horror styling.

Special Symbols

The Book of Horror symbol functions as Wild and Scatter in one. As a Wild it substitutes for all regular symbols across the 5 paylines. As a Scatter it pays an immediate multiplied prize for three, four, or five appearing anywhere on the reels and simultaneously launches 10 free spins. The start of the feature triggers a selection wheel that cycles through all regular pay symbols and stops on the Expanding Special for that round. That symbol covers its full reel on any spin where it creates a win. Three or more books during free spins retrigger the bonus.

Book Of Horror - Friday the 13th Bonus Feature & Special Features

Free Spins with Expanding Symbol

Three or more Book of Horror scatters anywhere on the 5x3 grid trigger 10 free spins. A selection wheel appears before the first spin, choosing one regular symbol as the Expanding Special for the entire round. Each time that symbol lands on a reel and contributes to a winning combination, it stretches from the top row to the bottom, turning a single-position hit into a full-reel column. With 5 paylines rather than the original game's 10, the coverage of each full-reel expansion is more focused but also more readable, when the expanding symbol covers three adjacent reels, it activates all paylines that run through those positions simultaneously. The witch expansion is the feature's headline outcome: five-reel coverage of the witch symbol, even on 5 paylines, produces payouts that approach the 10,000x ceiling at higher bet levels. Three or more books during the feature retrigger an additional 10 spins.

Buy Feature

The buy feature costs 104x the current total bet and delivers immediate entry into the free-spins bonus. The round runs identically to an organically triggered bonus: the selection wheel appears, one symbol is chosen as the Expanding Special, and 10 free spins proceed. For players focused on the jackpot potential of the feature rather than the base game, the buy-feature provides controlled access to the bonus without waiting for a natural scatter trigger. The cost is fixed at 104x regardless of which symbol the wheel subsequently selects, making it a high-variance purchase that pays off most cleanly when the witch is chosen as the expander.
