Joker Ra: Slot Overview

Artificial intelligence appears to be aiding software developers in repurposing old themes to generate innovative content. The world's first slot game to utilize AI for its visuals is the Joker Ra slot, developed by Endorphina. This intriguing game features a gameboard with 5 reels and 100 fixed paylines. With the assistance of AI, the graphics offer a contemporary and stylized take on well-known symbols, particularly those associated with Ancient Egypt and dark-themed gameplay. Within the game, you can observe the presence of a sun hovering above the pyramids, accompanied by an animated sandstorm in the backdrop. The musical elements, however, were crafted by human composers and draw inspiration from ancient Egyptian motifs.


It's worth noting that this title is optimized for mobile devices. If you're interested in exploring the potential of the Joker Ra slot, including its distinctive wild and scatter symbols, we recommend reading our comprehensive review of the game.




Joker Ra, developed by Endorphina, is a video slot game featuring 5 reels, 4 rows, and 100 paylines. The minimum bet you can place is $1, while the maximum bet is set at $80. The game boasts a return to player (RTP) rate of 96.07% and offers medium volatility gameplay. If luck is on your side during your venture into ancient Egypt, you have the chance to win a maximum payout of 3,000 times your initial bet.


Upon stepping into the realm of Joker Ra, you may initially find yourself overwhelmed by its mystical atmosphere. However, this enchanting setting also presents exciting features such as the Wild Symbol, Scatter Symbols, and the Gamble Feature.


Joker Ra: Slot Features

By achieving specific combinations with the eleven symbols displayed on the payout table of Joker Ra slot, you can experience thrilling outcomes. Among these symbols, eight are regular and generate payouts when you land three, four, or five of the same kind on any of the one hundred paylines. It's important to note that the highest-paying symbol rewards you for landing two to five of them on a payline. For more details regarding the prizes, you can refer to this section of our Joker Ra slot review.


The four symbols with the lowest payouts are represented by a Scorpio, a Crocodile, a Bird, and a Cat, offering 0.1 to 1 times your initial bet. The Ornament with wings symbol grants winnings ranging from 0.2 to 2 times your stake, while the Scarab symbol provides rewards of 0.4 to 5 times your bet. Additionally, the Eye of Horus yields payouts of 0.4 to 5 times your stake, and Anubis offers winnings of 0.1 to 30 times your total bet.


There are two Scatter symbols in the game, with one of them granting a reward worth 20 times your bet, and the second one offering payouts ranging from 3 to 100 times your initial stake. It's important to note that the Wild symbol does not provide such payouts.




The Wild Symbol in Joker Ra is represented by a grinning pharaoh character with a long beard. This unique symbol combines elements of a Joker and the deity Ra, and its creation involved the use of artificial intelligence. The Wild Symbol has the ability to substitute for all regular paying symbols, except for the Scatter symbols.


There are two Scatter Symbols in the game. The first one is the Pyramid Scatter, which can appear on any reel and pays out 3 times, 20 times, or 100 times the bet when you land 3, 4, or 5 of them, respectively. Unlike regular symbols, the Scatter Symbols don't need to be on a specific payline to generate a win. The second Scatter symbol is the Pharaoh's Chest Scatter, which only appears on reels 1, 3, and 5. Landing 3 of these symbols awards a payout of 20 times the bet.




Joker Ra also features a Gamble Feature, also known as the Risk Game. Whenever you achieve a win, you have the option to activate this feature. In the Gamble Feature, you are presented with a playing card belonging to the dealer, and you get to choose one of four face-down cards. If the card you select beats the dealer's card, your win is doubled. At this point, you can choose to cash out your winnings or attempt to double them again.


You can play the Gamble Feature up to 10 times consecutively, as long as you continue to win each round. However, losing a round results in the loss of both the Risk Game and your initial win. It's important to note that all face-down cards have the potential to be both lower and higher than the dealer's card.


In the Gamble Feature, there is a special Joker card that surpasses all other cards. This Joker card can only be drawn by the player and not by the dealer. The average return to player (RTP) of the Gamble Feature is 84%, and your chances of winning are higher when the dealer's card is lower. Here are the approximate win probabilities based on the dealer's card:


  • 2: 162%
  • 3: 121%
  • 4: 113%
  • 5: 101%
  • 6-8: 100%
  • 9: 92%
  • 10: 78%
  • J: 69%
  • Q: 66%
  • K: 64%
  • A: 42%
