The main theme of the slot is the adventures of Indiana Jones in Egypt , and the researcher is depicted in the game without copyright infringement. Among the symbols of cards with a face value from ace to ten, you will also find many sarcophagi and scarabs.
The theme will appeal to fans of the style of hieroglyphic writing , to which this slot is very well adapted. The pictures are perfectly displayed on the drums in the form of symbols.
Who among us would not want to steal the mummy’s treasure ? And in this slot it becomes possible when winning combinations fall on the reels.
Book of Ra is a slot machine with five reels and nine paylines . You can choose any number of lines from 1 to 9, but they are added in a permanent order, so they can not be selected at your discretion (this does not affect the percentage of payments, so do not worry about it).
In all respects, this is a fairly standard slot machine. However, it offers bonuses in the form of ten free spins and the option to expand the symbol (more on this later). The Gamble function is also available in the game, which slightly diversifies the monotonous rotation of the drum.
The Gamble option allows you to guess the color of the card (red or black) and thus double your winnings or lose the stack up to five times. This adds variance to the game, but does not affect the payout percentage.
A nice surprise in Book of Ra is the adaptive payout table , so you can see payouts for the selected number of lines and denominations of coins, not multipliers, so you will always know the amount of possible winnings.
Rate rates, payout percentage and variance
The payout percentage in this game is slightly below average . Some sites give a payout percentage of 95.18%, although the game’s creators note an even lower theoretical figure of 92.13%.
The variance here is average . Basically, you should expect to win every four spins. Yes, payments are frequent but insignificant.
The Book of Ra slot is quite simple, but contains some good options . The multi-purpose Book of Ra symbol and the Gamble option are fun additions to the gameplay, and the ability to break a jackpot in the bonus round only adds interest and excitement.
It is also one of the most popular classic slots with multiple sequels.
There is probably something special about this game if it attracts so many players even though the payout percentage is very low.
