Book of Mummy is a 5x3 ancient Egypt slot from KA Gaming where the central mechanic hands control to a single book symbol: it acts as Wild on every spin and as Scatter for the free spins trigger, then becomes the source of an Expanding Symbol during the bonus round. A 96% RTP and 20 fixed paylines, with free spins scaling from 10 to 25 depending on how many books land at once. Playable on desktop and mobile at Wild.io.
What is Book of Mummy?
Book of Mummy is a 5x3 video slot from KA Gaming with a 96% RTP, medium volatility, and 20 fixed paylines. The core mechanic centers on the Book of Mummy symbol, which functions as both Wild and Scatter simultaneously: as a Wild it substitutes for all standard paying symbols in the base game, and three or more on the reels trigger the free spins bonus.
During the free spins feature, the game selects a random symbol at the start of the round to serve as the Expanding Symbol. Each time that symbol lands on any reel during the bonus, it stretches to cover all three rows, creating stacked wins across every payline that crosses that reel. Landing the highest-value hieroglyphic or pharaoh symbol as the expanding pick is where the biggest wins originate.

Book of Mummy Slot Theme & Graphics
Book of Mummy recreates the classic ancient Egypt aesthetic: hieroglyphic-covered stone reels, golden scarabs, wrapped mummies, and pharaoh imagery make up the visual identity. The backdrop shifts between warm desert tones and the deep blues of a temple interior. KA Gaming's art renders the symbols in a polished illustrative style rather than photorealistic detail, keeping the reel action clear even at smaller mobile screen sizes.
The sound design uses orchestral strings and light percussion to reinforce the archaeological adventure feel. When the Book Scatter lands, a distinct chime marks the event. During free spins, the tempo lifts and a second layer of sound plays under the Expanding Symbol animations. The 5x3 layout scales cleanly to vertical mobile mode, making all 20 paylines visible without zooming.
Book of Mummy Slot Symbols & Paytables
Book of Mummy uses a two-tier symbol set common to the Egypt slot genre: card ranks at the lower end and themed Egyptian icons above, anchored by the Book as the most important symbol in the game.
Low Value Symbols
The lower-value symbols are card ranks rendered in an Egyptian stone-carved style. They appear across all five reels and form the bulk of base-game winning combinations on the 20 paylines. While their individual payouts are modest, they keep the session active between the higher-value hits and serve as the most common candidates when the game chooses the Expanding Symbol for free spins, though that random selection can land on any symbol.
High Value Symbols
The upper paytable features Egyptian-themed premium symbols: scarab beetles, pharaoh portraits, and hieroglyphic decorations make up the mid-high tier, with the top premium icon paying the most for a five-of-a-kind line hit. Landing the top premium symbol as the Expanding Symbol during free spins is the scenario that produces the largest wins, as expanded reels covering all three rows can hit across multiple paylines simultaneously.
Special Symbols
The Book of Mummy is the most important symbol in the game. It functions as Wild, substituting for all other paying symbols to complete winning combinations in the base game, and simultaneously as Scatter, where three, four, or five Books anywhere trigger 10, 15, or 25 free spins respectively. During free spins, the Book Wild remains active as a substituting Wild AND a random standard symbol is chosen to become the Expanding Symbol, growing to fill entire reels on every appearance.
Book of Mummy Bonus Feature & Special Features
Free Spins with Expanding Symbol
The free spins round in Book of Mummy is the primary bonus mechanic and provides the most substantial win potential in the game. The feature activates when three, four, or five Book Scatter symbols land anywhere on the reels during base play. Three Books award 10 free spins, four Books give 15, and five Books grant 25, the escalating scale means pursuing the five-Scatter trigger is worth the patience, as 25 spins versus 10 produces a substantially different bonus session. Before the free spins begin, the game randomly assigns one symbol as the Expanding Symbol for the entire round. On every spin of the bonus, if the Expanding Symbol lands on any reel, it stretches vertically to occupy all three rows of that reel. Because the 20 paylines cross that expanded reel in multiple configurations, a single expanded position can complete many simultaneous winning combinations. The Book of Mummy Wild also stays active throughout free spins, substituting as normal alongside the expanding symbol behavior. A run where the top premium Egyptian icon is the Expanding Symbol and it lands on two or three reels in a single spin is the game's maximum potential scenario.
