The theme of this slot is ancient Egypt - a theme done to death, unfortunately. The good news is that the theme only works as a background, and really has no other impact on the game. The focus is a 100 % on gambling, without any video sequences or mini elements expanding the theme. So let's just leave the theme and take a closer look on the concept.
"Less is more" is a well known saying, one that fits the concept of Book of Ra perfectly. As simple as possible, but still with some variety to keep it interesting. It consists of the regular symbols 10, J, Q, K and A, as well as 5 other symbols who are worth more.
Paylines are made from left to right, there are only 10 different ways to win - short story shorter; you learn the basics in minutes, even if this is the first time you lay your eyes on a slot.
What makes this simple game so extraordinarily interesting is the "Gamble element", where you get the chance to gamble your every win by choosing to double-or-nothing.
