Book of Flames

Book of Flames gives Novomatic's Egyptian book template a fire-and-sorcery makeover and then doubles the bonus options: a free spins round with expanding symbol for players who want the classic flow, and a Hold and Win mechanic triggered by six or more golden Book of Fire symbols for players who prefer the coin-collect structure. The 5x3 grid runs 10 paylines, a 94.06% RTP, high volatility, and a top win of 1,346x. Two distinct bonus paths on the same grid makes Book of Flames more varied than a single-mechanic book slot. Playable on desktop and mobile at Wild.io with crypto deposits.

What is Book of Flames?

Book of Flames is a 5x3 video slot from Novomatic with 10 paylines, 94.06% RTP, high volatility, and a 1,346x max win. Its dual-bonus structure separates it from standard book slots: three or more Book symbols trigger expanding free spins in the traditional way, while six or more Book of Fire bonus symbols launch a Hold and Win respins round instead.

The Hold and Win mechanic uses three respins that reset on every new bonus symbol landing on the grid. Fill all 15 positions with bonus symbols and the feature ends immediately with a full-board payout. Jackpots can drop during the Hold and Win phase. The two bonus paths use different trigger symbols, so both can activate across the same session without competing.

Who will enjoy this game the most?

You will probably enjoy this game if you like:

• Book slot players who want both expanding free spins and a Hold and Win mechanic in one game rather than choosing between titles
• High-volatility players comfortable with a 29.02% hit frequency and a 1,346x ceiling
• Those who enjoy Egyptian fire-and-magic themes as a variation on the traditional sand-and-stone aesthetic
• Crypto casino players who want a 94.06% RTP with jackpot potential via the Hold and Win bonus
• Mobile players at Wild.io, as the 5x3 layout scales well on portrait screens

Book of Flames Slot Theme & Graphics

Book of Flames moves Egyptian iconography into a fire-magic register: the reels sit against a backdrop of burning parchment scrolls and glowing sigils, with ember particles drifting across the grid during bonus activations. Spellbooks and flame motifs replace the sandstone temple of older Book of Ra designs, giving the game a sorcerer's library quality rather than an archaeological dig.

Symbol art uses deep oranges and crimson against dark backgrounds, keeping contrast high for both desktop and mobile viewing. The Book of Fire bonus symbol is distinct from the regular Book of Flames scatter, with a full-flame surround that makes it immediately identifiable when it starts accumulating across the reels toward the six-symbol Hold and Win threshold.

Book of Flames Slot Symbols & Paytables

Book of Flames uses a dual-symbol structure where the regular Book and the Book of Fire bonus symbol serve different mechanical roles on the same grid.

Low Value Symbols

Card ranks Ace, King, Queen, and Jack represent the low tier. They land frequently across the 10 paylines and provide the base-game wins that sustain sessions between bonus triggers. During free spins, if any low card rank is selected as the expanding symbol, it can fill entire reels and pay across all active lines, converting normally modest payouts into higher-value combinations.

High Value Symbols

Spellbook and flame-based premium symbols occupy the high tier. These stylised magical objects pay more per combination than card ranks and form the larger base-game wins when two or more land on adjacent reels in a payline. The top premium symbol is the key visual anchor of the game's sorcery theme.

Special Symbols

Two separate special symbols operate on the same grid. The regular Book of Flames symbol acts as both Wild and Scatter: as wild it substitutes for all regular symbols, and as scatter three or more anywhere on the grid trigger free spins and a randomly selected expanding symbol for the 10-spin round. The Book of Fire is the Hold and Win trigger piece: six or more of these golden-flame bonus symbols in one spin lock in place and launch three respins. Only Book of Fire symbols can land during those respins; regular symbols are temporarily removed from the reels.

Book of Flames Bonus Feature & Special Features

Free Spins with Expanding Symbol

Three or more Book of Flames symbols anywhere on the 5x3 grid trigger 10 free spins. Before the round begins, one regular symbol is randomly chosen as the expanding icon for the entire bonus. During those 10 spins, every time the chosen symbol lands it stretches to cover its full reel from top to bottom and pays on all active paylines regardless of vertical position. A retrigger is possible by landing three or more Book symbols during free spins, adding more spins with the same expanding icon active. This is the traditional book-slot path to the game's highest outcomes within the free spins mechanic.

Hold and Win

Six or more Book of Fire bonus symbols landing in the same spin trigger the Hold and Win feature. All activating symbols lock in their current positions and three respins begin. During those respins only Book of Fire symbols can appear, and every new one that lands resets the counter back to 3, extending the feature. If all 15 reel positions fill with Book of Fire symbols before respins run out, the feature pays immediately without waiting for the counter to expire. Jackpot symbols can replace standard Book of Fire symbols during the respins, each awarding a fixed jackpot prize on top of the accumulated bonus symbol values. The Hold and Win path produces the game's jackpot outcomes and sits alongside the free spins as an equal-priority bonus route rather than a secondary feature.
