BOOK
OF RA

The legendary Novomatic slot that ignited Australia’s love affair with Egyptian pokies. One sacred Book symbol unlocks 10 free spins with an expanding wild that can cover an entire reel — and reactivates endlessly. Over two decades old, still unmatched.

Why Book of Ra
Conquered Australia

When Novomatic released Book of Ra in 2005, it changed the slot industry permanently. The game introduced what would become the defining mechanic of an entire generation of pokies: the combined wild and scatter symbol that triggers free spins and then expands to fill entire reels.

Australian players took to it immediately. The high volatility created exactly the boom-and-bust tension that pokies players crave — long dry patches punctuated by explosive free spin rounds where a single expanded Horus or Pharaoh can return 500× or more. Today, over 20 years later, it remains one of the five most-played slots in Australia.

Free Spins &
Expanding Symbol

Book of Ra’s free spins round is unlike any other. The moment 3 or more Book symbols land simultaneously, the game pauses, a single symbol is randomly selected, and 10 free spins begin with that symbol as an expanding special.

If the chosen symbol appears on one reel during a free spin, it instantly expands to fill that entire reel — regardless of position. Get it on multiple reels and the combination calculates across the full expanded display, not just standard paylines. This is how 500× to 2,000× wins happen.

Win Estimator

Estimate what your 10 free spins could deliver based on your bet size and which expanding symbol fires. Results are illustrative — actual outcomes depend on the random expanding symbol and game RNG.

Always Play All 10 Lines

Book scatters pay regardless of paylines, but your regular wins require active lines. Playing fewer lines does not reduce risk proportionally — it reduces win opportunities. Always activate all 10 paylines, adjusting your coin value instead of line count.

Budget for High Volatility

Book of Ra is high volatility. Budget a minimum of 100 spins at your chosen stake before expecting a free spin trigger. On average, the free spins fire roughly every 150–200 spins. With a $200 session budget, keep spins to $1 max to ensure you see multiple triggers.

Bonus Wagering Strategy

Book of Ra contributes 100% toward PlayCroco’s wagering requirement. The 96% RTP makes it efficient for clearing — but the high volatility means balance swings are large. Use $0.50–$1 spins on bonus funds, not maximum stakes. Smaller bets give more spins and more free spin triggers.

Chase the Retrigger

The free spins retrigger adds another 10 spins when 3+ Book symbols land during the bonus. If this happens early in the round (spins 1–3), you’re in prime position for a massive session. Players who bank big wins from Book of Ra almost always have a retrigger involved.

Mobile Play Tips

Book of Ra at PlayCroco is fully HTML5 and mobile-optimised. The expanding symbol animation is visually impressive on mobile screens. Use Autoplay (set to 50 or 100 spins) to maintain consistent betting discipline. Stop Autoplay conditions at a balance threshold to lock in profits automatically.

Best Expanding Symbol

The Horus symbol is the most valuable expanding choice — 2,000× multiplied by a three-reel expansion at a $2 spin can deliver $12,000+. The Pharaoh is second best. Royals (A/K/Q/J) as the expanding symbol still retrigger well but pay much less per expansion. There’s no way to influence which symbol is selected — it’s always random.
