Secret Book of Amun Ra

Secret Book of Amun Ra is an Egyptian-themed 5x3 video slot from Booming Games with 10 paylines, 95.4% RTP, high volatility, and a 10,000x maximum win. The mechanic that sets it apart from similar book-style slots is a sequential expanding symbol system during Free Spins: the lowest-value symbol expands to fill reels, then gets eliminated, and the next symbol in the hierarchy takes its place. Combined with a bonus buy option and unlimited retrigger potential, the feature can sustain itself through the entire symbol ladder. Playable on desktop and mobile with crypto support.

What is Secret Book of Amun Ra?

Secret Book of Amun Ra is a 5x3 video slot from Booming Games with 95.4% RTP, high volatility, 10 paylines, and a top win of 10,000x your bet. Its standout mechanic is a sequential expanding symbol feature during Free Spins: the lowest-paying symbol expands first, then is eliminated after winning, and the next lowest becomes the new expander.

Booming Games built this game within the well-established book slot format, but the sequential elimination twist moves it past a standard single-expanding-symbol design. The Book of Amun Ra acts as both Wild and Scatter, paying direct prizes for three or more and triggering 8 Free Spins. During the bonus, each expansion-and-elimination cycle gradually pushes the active expander up the symbol value ladder, so a long free spins run can reach the highest-paying Horus and Amun Ra symbols as expanders.

Who will enjoy this game the most?

You will probably enjoy this game if you like:

• High volatility players who enjoy book-style expanding symbol bonuses and want a more escalating version

• Bonus buy players who want direct access to the Free Spins feature via the buy option
• Players chasing a large max win ceiling of 10,000x supported by unlimited retrigger potential inside the bonus

How To Play Secret Book of Amun Ra Slot - Step By Step

Head to Wild.io and create a free account to start playing Secret Book of Amun Ra.

1. Set your bet across 10 fixed paylines; use the Bonus Buy option to purchase direct entry into the Free Spins feature if you prefer not to wait for a natural trigger.
2. Spin and watch for the Book of Amun Ra symbol: it acts as both Wild and Scatter, substituting for all other symbols on the reels in standard play.
3. Landing 3, 4, or 5 Books pays direct prizes of 2x, 10x, or 100x your bet respectively, independent of payline position.
4. Landing 3 or more Books triggers 8 Free Spins. Before the feature starts, the game identifies the lowest-paying symbol currently on the reels as the first Expanding Symbol.
5. During Free Spins, when enough Expanding Symbols land they stretch vertically to fill entire reels. After the expanding symbol completes its win, it is permanently eliminated from the feature, and the next-lowest-paying symbol becomes the new expander.
6. Retrigger the feature by landing 2-3 Books during Free Spins for 2-3 additional spins, resetting the countdown and potentially cycling through more expanders as you go.

Secret Book of Amun Ra Slot Theme & Graphics

Secret Book of Amun Ra uses a classic Egyptian visual treatment grounded in the Booming Games art style. The reels sit inside stone temple columns, with hieroglyphic panel borders and a warm ochre-and-gold colour palette evoking ancient stonework and candlelight. Booming Games populated the premium symbol positions with the gods themselves: Horus, Amun, and Amunet appear in detailed illustrations drawing from traditional Egyptian iconography, alongside a Winged Ankh and a golden Scarab Beetle. The overall mood is reverent rather than action-heavy, leaning into the mystery angle its title promises.

The Free Spins backdrop shifts slightly to signal the bonus is active, with ambient light changes around the reels. When an expanding symbol triggers, it stretches vertically with a smooth animation that covers the reel positions before resolving the win. On mobile the 5x3 layout renders cleanly at all sizes, and the premium symbol artwork retains its detail even on smaller screens. The symbol elimination mechanic is communicated clearly: once a symbol is removed from the active pool its position in the paytable dims, keeping track of which expander is currently active.

Secret Book of Amun Ra Slot Symbols & Paytables

Secret Book of Amun Ra uses two tiers of standard symbols plus the Wild Scatter Book. High-value symbols represent Egyptian gods and artefacts; low-value positions use the standard card suite (10 through Ace). During Free Spins, the game cycles through these symbols sequentially as expanders, starting from the lowest and eliminating each after it contributes to a win.

Low Value Symbols

The five low-value positions are the card rank symbols: 10, J, Q, K, and Ace, styled with Egyptian motifs rather than standard playing card designs. These pay the smallest amounts across the 10 fixed paylines and are the first symbols designated as Expanding Symbols at the start of the Free Spins feature. Their low payout rate means the early expanding cycles deliver modest prizes, but their elimination from the reels progressively leaves higher-value symbols to dominate the available positions as the bonus continues.

• 10
• J
• Q
• K
• A (card suits)

High Value Symbols

Five Egyptian-themed premium symbols occupy the high-value tier. The Scarab Beetle is the lowest among the premiums, followed by the Winged Ankh, Amunet (the female counterpart to Amun), Amun in his golden falcon form, and Horus as the highest-paying standard symbol. Landing 5 Amun Ra falcon symbols across 5 of a kind is the top payline combination. When the sequential elimination mechanic works through the card ranks during Free Spins and reaches the premium tier, these symbols become the active expanders, which is where the game's 10,000x maximum win potential becomes reachable.

• Scarab Beetle
• Winged Ankh
• Amunet
• Amun (falcon god)
• Horus

Special Symbols

The Secret Book of Amun Ra symbol is the game's only special symbol and serves both roles simultaneously: it acts as a Wild, substituting for all other symbols on the reels, and as a Scatter that pays direct prizes and triggers the bonus. Landing 3 Books pays 2x your bet; 4 Books pays 10x; 5 Books pays 100x, independent of paylines. Landing 3 or more also triggers 8 Free Spins. Inside the Free Spins, landing 2 Books awards 2 additional spins and landing 3 Books awards 3 additional spins, creating the unlimited retrigger potential that allows the expanding symbol cycle to progress deep into the premium tier.

Secret Book of Amun Ra Bonus Feature & Special Features

Sequential Expanding Symbol Free Spins

The Free Spins feature is triggered by landing 3 or more Secret Book of Amun Ra Wild Scatter symbols, awarding 8 spins. Before play begins, the lowest-value symbol on the paytable is designated as the Expanding Symbol for that round. When enough of these symbols land during a free spin, they expand vertically to fill all positions on their reels, paying across all 10 paylines. Once that expanding symbol contributes to a win, it is permanently eliminated from the reels and the symbol pool for the rest of the feature. The next-lowest-paying symbol is then designated as the new Expanding Symbol. This cycle continues, working up the paytable from card ranks through to the premium Egyptian deity symbols. A free spins run with multiple retriggers can theoretically cycle all the way to Horus or Amun as the active expander, which is the path to the 10,000x maximum win. Retriggers inside the feature award 2 additional spins for 2 Books and 3 additional spins for 3 Books.

Bonus Buy

Secret Book of Amun Ra includes a bonus buy option that lets players purchase direct entry into the Free Spins feature without waiting for 3 or more Book symbols to land naturally. The cost is set as a multiple of the current total bet. This is the feature that makes the 10,000x ceiling most relevant for high-stakes players: rather than grinding the base game for a natural trigger, bonus buy slots players can target the Free Spins directly and rely on the sequential expanding symbol mechanic to generate the payout. The bonus buy buy option is one of the reasons the game carries high volatility, since the feature's variance is concentrated.
