The Book of Ra slot machine was a huge success, so it doesn't come as a surprise that Novomatic launched Book of Ra Deluxe and Book of RA 6.
Making Book of Ra Deluxe 10 lines instead of 9 lines and adding in some modern features, there are very few noticeable differences between the two slots.
Features of the deluxe edition include expanding wilds and free games.
Book of Ra Deluxe features an ancient Egyptian theme with pyramids in sight.
You will be required to search through the pyramids to uncover hidden Pharaoh's treasures.
The symbols will get you into an adventure mood and they include the Treasure Hunter, the Book of Ra, Scarabs, and Sarcophagus.
You will also encounter generic poker card values like the ones that are used for online blackjack games, but in hieroglyphic font.
The Book of Ra is the wild and scatter at the same time.
Three or more Book of Ra's will trigger 10 free spins with a special expanding symbol.
A special expanding symbol is randomly selected at the beginning of the free spins.
After the payout of regular symbols is made, the special symbol expands to cover up to 3 positions on a reel and pays like a regular symbol but also even on non-adjacent positions and on all lines played.
The expanding is only triggered if enough symbols for a win are present.
