Crypto slot game Book of Ra Deluxe: play for Bitcoin, Litecoin, Ethereum

The slot machine in the Book Of Ra Deluxe casino, or the legendary "Books", is the most famous slot from Novomatic. This is an improved version of the slot of the same name, which has gone through at least 15 editions. Despite the fact that the slot is far from new, it still remains in demand among gambling fans.

About the slot

The slot machine uses the traditional structure of 5 reels and 3 rows of symbols. In contradistinction to the original slot version, it provides not 9, but 10 lines for bets and you can activate any number. The line bet varies from 0.01 to 5 credits in casino currency and the spin value reaches 50 units.

Winning positions are constituted from left to right along the active lines. Some symbols are already paid for 2 identical symbols in a row. The maximum payout ratio is x5000. RTP at the time of the game release was considered average, but for modern slots, the return rate of 95.1% is already perceived as low.

It's interesting, online casinos licensed in the UK use a version with an even less attractive RTP of 94.26%. This is the percentage indicated by Novomatic (Greentube) when passing certification in the UK Gambling Commission. There is no progressive jackpot.

Almost any winnings in the usual mode can be doubled using the risk game, which is launched by clicking on the Gamble button. True, there are restrictions for it. For example, it is not available when automatic scrolling is activated. Also, in the doubling round, you cannot win more than 500 total bets.

If the potential increase in winnings exceeds the denoted limit, the risk game simply will not start. That's why when collecting a combo of the five most valuable icons, the Gamble button turns out to be inactive, as in the case of collecting several expensive combinations, the payments for which are summed up.

The risk game takes place in a standard way: the gambler enters the field with a flashing card turned face down. He must choose what color the suit of the card will be. If the correct answer is guessed the winning amount is doubled and the round continues, but if the player makes a mistake he loses all the money that he managed to win.

Simple rules can be learned in a demo mode. The presence of a demo version allows you to play the Book Of Ra Deluxe slot machine for free and without registration. In this case, all functions of the slot remain active.


The game action takes place in Egypt. Above, behind the logo you can see the silhouettes of the majestic pyramids and the desert at sunset. The drums are placed against the background of hieroglyphs on the wall of the pharaoh's tomb. The player gets the impression that he got inside the pyramid. The atmosphere of mystery is complemented by high paying symbols with a pharaoh mask, a figurine of the god Ra and a precious scarab decoration. But the most expensive standard symbol is considered to be a picture with a portrait of an archaeologist whose image resembles Indiana Jones.

Low paying pictograms contain card meanings 10, J, Q, K and A, styled as ancient Egyptian hieroglyphs.


The new slot version uses a dynamic paytable, that is the size of payments on the page with the rules changes as the spin cost increases or decreases. In such a situation, to display the odds, it is enough to set the linear bet at the level of 1 credit in the casino currency.

There is only one special symbol in the slot, but it performs two functions at once - a wild and a scatter. It looks like an ancient tome. It is because of this pictogram that the slot got its name "Books". It is believed that all the wisdom of the celestials is concentrated in the Book of the god Ra. This symbol hides the main secrets of the game.

As a wild the book replaces all standard icons in prize combinations without exception. As a scatter, the icon is paid outside the prize lines with the x20, x200 and x2000 odds to the total bet for 3, 4 or 5 symbols, respectively. Collecting of three or more pictograms activates the bonus feature and launches free spins.

Bonus game

The slot does not have a thematic bonus level, but for a combo of 3-5 scatters, a gambler gets 10 free spins. During their use, you can get additional free spins by re-collecting at least three scatters on the reels. According to the plot such a combo represents the finding of the Book of Ra by the archaeologist in the tomb of the pharaoh, what is the short video about, which is shown right in the cells of the slot. The player then sees how pages in the ancient book are turned over, on which familiar symbols are drawn. A picture randomly chosen in this way turns out to be a bonus sign.

During free spins, after the payments are accrued in the standard way for the formed chains of symbols, the bonus function is activated. If there is a bonus sign on the reels, it expands to the full height of the reel and the gambler receives additional payouts for the combo, even if the signs are not located on adjacent reels. For example, any high-paying symbol, having become a bonus symbol, brings a cash payment, even if it appears on the first and fifth reels!

Slot machine interface

The slot is regularly updated and improved by the developer. At the same time, since the release, the slot interface has not changed much in appearance. But now it can be run on any device and the control panel is in line with modern standards. The interface elements are concentrated at the bottom of the screen on translucent buttons. Here you have possibility select how many active lines use, define the size of the bet, activate the auto mode or call the main menu to download the full rules and see the paytable.
