Book of Sevens

About Book of Sevens

Book of Sevens is a classic-fruit and Egyptian-themed slot from Crucible Gaming, released in March 2025. The game blends two well-trodden slot formats. The classic Vegas fruit machine, with its 3x3 layout, lucky 7s, and bell symbols. And the Book of Ra-style expanding symbol mechanic, where a Book scatter triggers free spins with one randomly chosen symbol expanding to cover full reels. The reels are framed against an Egyptian temple backdrop with hieroglyphic stonework, while the symbols themselves keep the cherries, lemons, and 7s of a traditional fruit slot.

The game has an RTP of 94% in the version available at Midnite, low volatility, and a maximum win of 5,064x your bet. The bonus structure is built around the Book scatter symbol, which triggers a Free Spins round where one randomly selected symbol expands to fill its entire reel, paying as if it had landed on every payline.

How to Play Book of Sevens

The grid is 3 reels by 3 rows, with 5 fixed paylines that are always active. Stakes at Midnite start from £0.05 per spin, set using the coin stack icon with plus and minus buttons. Wins form when three matching symbols land on adjacent reels from left to right on a payline.

Lower-paying symbols are classic fruit machine icons: cherries, lemons, oranges, plums, and watermelons. Higher-paying symbols are bells, BAR symbols, and Lucky 7s, with the Lucky 7 acting as the top regular paying symbol.

Three Book symbols on the reels trigger the Free Spins round. The Book also doubles as a wild and a scatter, substituting for all standard paying symbols on a payline as well as triggering the bonus when enough land. An autospin function is available with optional loss limits and single-win limits for responsible play.

Book of Sevens Features

The bonus structure is intentionally lean, following the classic Book of Ra-style format that has become a recognisable formula in the slots category.

• Wild and Scatter Combined: The Book symbol acts as both the wild (substituting for all standard paying symbols to help complete winning combinations) and the scatter (triggering the Free Spins round when enough land on the reels).
• Free Spins: Triggered by landing 3 Book symbols on the reels. The Free Spins round awards a set number of free spins with a special expanding symbol feature active throughout.
• Expanding Symbol: Before the Free Spins round begins, one symbol is randomly selected to act as the expanding symbol for the duration of the bonus. When that symbol lands on any reel during a free spin, it expands to fill all three positions on that reel. If the expanding symbol covers the necessary reels for a winning combination, it pays out as if it had landed on every payline of those reels, regardless of position.
• Free Spins Retrigger: Landing 3 more Book symbols during the Free Spins round retriggers additional free spins, with the same expanding symbol active.
• Bonus Buy: Available in some markets but not in the UK. UK players cannot use the Bonus Buy due to UK Gambling Commission regulations and must trigger the Free Spins round through landing the Book scatter symbol.

Book of Sevens Theme and Symbols

The setting is a blend of two classic slot worlds. The Egyptian temple aesthetic that frames most Book of Ra-style slots, with hieroglyphs and sandstone columns, sits behind the playing field. The reels themselves carry traditional fruit machine symbols with shiny chrome borders. The visual style leans warm and nostalgic rather than dramatic, with golds and reds dominating the colour palette. The soundtrack mixes Egyptian percussion in the base game with a more upbeat fruit-machine arrangement when wins land.

Lower-paying symbols are stylised fruit machine icons: cherries, lemons, oranges, plums, and watermelons. Higher-paying symbols are bells, BAR symbols, and the Lucky 7. The Lucky 7 sits at the top of the regular paytable as the highest-value symbol. The Book symbol completes the special set, acting as both the wild and the scatter.
