Book of Ra

Book of Ra is the slot that started the book-format genre. Novomatic released it in land-based form first, and the original 5x3 layout with 9 paylines, 92.13% RTP, and the expanding-symbol free-spins mechanic became the template every subsequent book slot copies. The Explorer symbol pays 5,000x your line bet and doubles as the target for the bonus round. It plays on desktop and mobile at Wild.io with full crypto support.

What is Book of Ra?

Book of Ra is a 5x3 video slot from Novomatic with a 92.13% RTP, high volatility, and 9 paylines. Its standout mechanic is a free-spins bonus where three or more Book scatter symbols trigger 10 spins with a randomly chosen expanding symbol that fills entire reel columns. The Explorer pays 5,000x a line bet and is the most valuable expanding symbol.

The Book of Ra itself acts as both wild (substituting for all paying symbols) and scatter (triggering the free spins). Before the 10 free spins begin, the game randomly selects one symbol to expand, meaning the same round can produce wildly different outcomes depending on which symbol is chosen. A Gamble Feature lets players double any win by guessing the colour of a face-down card, adding a risk layer on top of standard payouts.

Book of Ra Slot Theme & Graphics

Book of Ra immerses players in an Egyptian tomb-raiding adventure. The reels are framed against hieroglyph-covered stone walls with warm amber and gold lighting suggesting oil-lamp illumination deep in an ancient temple. Each symbol represents an artefact or figure from Egyptian mythology, drawn in the detailed illustrative style Novomatic established for the series.

The original release set the visual tone for every book-format slot that followed: premium symbols depicting the scarab beetle, the Statue of Horus, the Pharaoh sarcophagus, and the Explorer sitting against a dark desert-night sky. Sound design uses orchestral strings and percussion that rise during big wins, while the expanding-symbol animation shows the chosen icon growing to fill reel columns with a glowing outline. On mobile, the layout scales cleanly to portrait and landscape.

Book of Ra Slot Symbols & Paytables

Book of Ra uses two tiers of themed symbols plus the Book as the key special symbol, with Egyptian iconography across the premium tier.

Low Value Symbols

The low-value symbols are the card ranks: 10, J, Q, K, and A. They form the majority of base-game outcomes on the 9-payline layout and pay small but frequent amounts for three or more on a payline. Their primary function is keeping the session active between scatter triggers, and while they cannot drive major wins on their own, the A symbol pays better than the others for five-of-a-kind.

High Value Symbols

The high-value tier is where Book of Ra's Egyptian story lives. The Scarab Beetle, the golden Statue of Horus, and the Pharaoh Sarcophagus represent the mid-to-upper premium band. The Explorer sits at the top: five Explorers on a payline pay 5,000x the line bet, and if the Explorer is chosen as the expanding symbol during free spins, a reel-covering run at that value is the game's highest single-spin potential. The Pharaoh and Horus follow at lower payouts.

Special Symbols

The Book of Ra is the most important symbol in the game. It substitutes for all paying symbols as a wild, completing any line combination it touches. As a scatter, three or more landing anywhere trigger 10 free spins regardless of payline alignment. Before those spins begin, the game selects one random symbol to serve as the expanding symbol for the entire round: it expands to fill complete reel columns when enough copies appear on a single spin, and pays across every active payline in the process.

Book of Ra Bonus Feature & Special Features

Free Spins with Expanding Symbol

Three or more Book of Ra scatter symbols anywhere on the 5 reels trigger 10 free spins. Before the round starts, one symbol is randomly selected to serve as the expanding symbol for all 10 spins. When that symbol lands in sufficient quantity on any single spin, it stretches to cover the full height of any reel it appears on and then pays across all active paylines simultaneously. This is where Book of Ra can reach its 5,000x ceiling: if the Explorer is selected and hits three or more reels in a single spin, the payout calculation multiplies across all 9 paylines at once. Retriggers are possible if three or more Book symbols appear during the free spins, adding more spins to the remaining count. The randomness of the expanding symbol selection means two identical scatter triggers can produce drastically different bonus outcomes.

Gamble Feature

After any base-game win, Book of Ra offers a Gamble Feature where players guess whether a face-down card will reveal red or black. A correct guess doubles the win; a wrong guess loses it. Players can gamble up to four times in succession on a single win, potentially quadrupling the payout. This feature is optional and entirely risk-based, with no skill element. It exists as a way to boost smaller wins into something more meaningful but carries equal chance of losing the original win entirely.
