Have you ever wondered what are the differences between Book of Ra and Book of Ra Deluxe? The short answer is: different visuals and graphics. Both games being made by Novomatic but released in 2005 and 2008, respectively.
While the animations in Book of Ra Deluxe are newer and better looking some players still prefer the symbols and colors used in the Original Book of Ra.
In terms of features like free spins and double up there are no changes or differences. Changing something players love and are familiar with is not advised while keeping the name of the game.
