Few casino games have achieved the legendary status of Book of Ra - this groundbreaking slot essentially created an entire genre that continues to thrive today. Released by Greentube in 2005, this Egyptian-themed masterpiece has inspired countless sequels and imitators, yet players consistently return to the original for its pure, uncompromising gameplay experience.
About Greentube Provider Established in 1998, Greentube successfully transitioned from land-based gaming to become a premier online slot developer. Their expertise in converting popular physical machines into digital experiences has created an impressive portfolio featuring industry legends like Sizzling Hot, Lucky Lady's Charm, and of course, Book of Ra - each spawning multiple successful sequels.
Egyptian Theme & Visual Design Ancient Egypt themes dominate today's slot landscape, but Book of Ra was pioneering this concept nearly two decades ago. While the graphics appear vintage by modern standards, featuring classic animations and retro sound design, this nostalgic charm is precisely what attracts devoted players. The game captures the essence of archaeological adventure with an Indiana Jones-inspired explorer searching for buried treasures in forgotten tombs.
Book of Ra features a 5-reel, 3-row layout with 1-9 adjustable paylines - though we recommend activating all 9 for maximum winning potential. The betting range spans €0.01 to €10 per line, creating total stakes from €0.09 to €90 when all paylines are active.
Symbol Categories: • Premium symbols: Explorer (highest paying), Pharaoh, Statue, Scarab • Standard symbols: Playing card ranks (10, J, Q, K, A) • Special symbol: Book of Ra (Wild + Scatter)
Winning Requirements: • Low-value symbols need 3+ matching symbols from left to right • Premium symbols pay from 2+ matching symbols • All wins must form on adjacent reels starting from the leftmost position
The Book of Ra symbol serves dual functionality as both Wild and Scatter, making it the most valuable icon on the reels. This mystical book substitutes for all regular symbols in winning combinations while simultaneously triggering the game's signature bonus round.
Scatter Payouts:
• 3 Books: 2x total stake + free spins
• 4 Books: 20x total stake + free spins
• 5 Books: 200x total stake + free spins
While the base game offers steady entertainment, the free spins feature delivers the main excitement and winning potential that has captivated players for nearly two decades.
Landing 3+ Book symbols anywhere awards 10 free spins regardless of the triggering combination size. The feature can be retriggered indefinitely - each new set of 3+ Books during the bonus awards an additional 10 spins.
Special Expanding Symbol Mechanic: Before free spins begin, the Book of Ra opens to reveal a randomly selected symbol that becomes the special expanding icon for the entire feature. This chosen symbol offers revolutionary mechanics:
• Expands to fill entire reels when winning combinations are possible • Acts as a scatter symbol - pays anywhere in view without requiring adjacent positions • Triggers after regular line wins are calculated and paid • Awards wins across all active paylines simultaneously when expanded
The same bet level and active paylines from the triggering spin are maintained throughout the free spins feature, ensuring consistent wagering strategy.
Book of Ra operates with high volatility, creating an intense gaming experience where significant waiting periods between major wins are offset by substantial payout potential. This high-risk, high-reward structure means free spins may take time to trigger, but when they do, the expanding symbol mechanic can deliver impressive rewards up to 5,000x your stake.
The slot's mathematics favor patient players who can withstand dry spells while building toward those explosive bonus rounds that define the Book of Ra experience.
Our testing team conducted a comprehensive 200-spin session to evaluate Book of Ra's performance firsthand. Despite the high volatility and challenging mathematics, we triggered free spins twice during our session, providing valuable insight into the game's bonus mechanics.
First Bonus Round: • Pharaoh selected as expanding symbol • No expansions occurred during the feature • Final payout: 44x stake from regular free spin wins
Second Bonus Round (70 spins later): • Statue chosen as special symbol • Multiple expansions triggered showcasing the mechanic's power • Total reward: 70x stake
While we briefly exceeded our starting balance, the base game's unforgiving nature ultimately resulted in a net loss. The session confirmed Book of Ra's reputation for high volatility while demonstrating why the expanding symbol feature remains so compelling after all these years.
Book of Ra stands as one of history's most influential slot machines, creating the blueprint for an entire genre that continues thriving today. While countless developers have attempted to improve upon this formula, the original retains its magnetic appeal through pure, uncomplicated gameplay focused entirely on that thrilling free spins experience.
This slot proves that innovative mechanics trump flashy graphics - the expanding scatter symbol concept was so revolutionary that it remains virtually unchanged in modern Book slots. For players seeking authentic slot gaming heritage combined with genuine winning potential, Book of Ra delivers an experience that transcends its vintage appearance.
Pros: • Genre pioneer - created the entire Book slot category • Revolutionary free spins featuring expanding scatter symbols • Maximum wins reach 5,000x your total stake • Simple yet engaging gameplay mechanics • Retriggerable bonus rounds for extended play sessions
Cons: • Vintage graphics may feel outdated compared to modern slots • High volatility requires patience and adequate bankroll management
