Book of Ra Deluxe Free Spins — How to Trigger & What to Expect
The free spins round in Book of Ra Deluxe awards 10 spins with a randomly selected expanding symbol. Three or more Book scatters anywhere on the reels activate the feature. Retriggers add another 10 spins with no upper cap.
Triggering the Bonus Round
Three, four, or five Book of Ra symbols landing anywhere on the 5×3 grid trigger the feature. The Books do not need to appear on active paylines — any grid position counts. Based on a 30% overall hit rate and observed data, the bonus triggers approximately once every 100 to 120 base game spins. At $1 total bet, that means spending roughly $100 to $120 on average before entering free spins.
How the Expanding Symbol Works
Before the 10 free spins begin, the slot randomly selects one symbol from the paytable (excluding the Book itself). During the round, whenever this symbol lands on a reel and can form a win, it expands to cover all three positions on that reel. The expanded symbol pays in any position — it does not require adjacent reels. If the Explorer is selected and appears on all five reels, each reel shows three Explorers, creating wins on all 10 paylines simultaneously. That scenario produces the maximum payout of 5,000× the total bet.
Retrigger Mechanics
Landing three or more Book symbols during the free spins round awards an additional 10 spins. The same expanding symbol carries over. There is no documented cap on retriggers, though landing multiple consecutive retriggers is statistically rare. Each retrigger extends the round without resetting any accumulated wins.
Expected Returns from Free Spins
Community-reported averages suggest a typical bonus round returns between 30× and 80× the triggering bet. Results vary dramatically based on which symbol becomes the expander. A round with the Explorer or Pharaoh as the expanding symbol tends to produce larger payouts (100×+ possible). A round with a low-card symbol (10, J) typically returns 15× to 40×. The 2× multiplier on all free spin wins doubles every payout compared to identical base game combinations.
