The slot that defined a genre
Book of Ra deluxe is the 2008 online remake of Novomatic's land-based hit, played on 5 reels, 3 rows and 10 fixed paylines. Novomatic's own game sheet rates it at the top of its volatility scale (5 of 5), and the deluxe version added a tenth payline and reworked graphics over the 9-line original.
The Book of Ra symbol is both wild and scatter: three or more books anywhere award 10 free games.
Free games and the expanding symbol
Before the free games start, one regular symbol is randomly selected as a special expanding symbol. When it lands during free games it can expand to cover entire reels and pays on all lines regardless of adjacency — landing the explorer as the special symbol is the game's headline win. Free games can be retriggered with three more books.
A red/black card gamble is available on any base-game win.
RTP versions
The standard published RTP is 95.10%, and Greentube also distributes lower operator configurations of 94.26%, 92.13% and 90.05% — worth checking in the paytable of the casino you play at.
