Joker Ra Slot Overview
Joker Ra is an Egyptian-themed video slot developed by Endorphina, built on a 5-reel, 4-row grid with 100 fixed paylines. From a math perspective, the game runs at 96.07% RTP with medium volatility and caps out at 3,000x the bet. Notably, Endorphina used AI-generated artwork for the visuals, blending ancient Egyptian iconography with a modern Joker character.
Bets range from 1 to 80 per spin. The feature set is deliberately minimal: no free spins, no bonus rounds, no cascading mechanics. Instead, the slot relies on expanding wilds, dual scatter payouts, and a Risk Game for its win potential. I find this stripped-back approach refreshing but also limiting; not everyone will enjoy a slot with so few bonus triggers.
Symbols and Paytable
Anubis sits at the top of the paytable as the only regular symbol that pays for just 2 matches on a line: 0.10x, 0.50x, 2x, and 30x the total bet for 2, 3, 4, and 5 of a kind respectively. Eye of Horus and Scarab are mid-tier symbols paying up to 5x, while the Wings emblem pays up to 2x. Four low-paying symbols (Sphinx Cat, Falcon, Crocodile, Scorpion) all return 1x the bet for a full line of five.
Two scatter types exist. The Pyramid of the Sun lands on all reels and pays 3x, 20x, or 100x the bet for 3, 4, or 5 anywhere on the grid. The Pharaoh's Chest only appears on reels 1, 3, and 5, paying 20x for a full set of 3. The numbers tell you that scatter payouts alone can deliver meaningful returns, especially the Pyramid at 100x for five.
Joker Ra himself is the wild. He appears exclusively on reels 2, 3, and 4, substitutes everything except scatters, and expands vertically to fill the entire reel when he can participate in a winning combination. The expanding mechanic is the primary way the slot generates larger hits in the base game.
Symbol Payouts

Gamble Feature and Risk Game Mechanics
Every winning spin unlocks access to the Risk Game, a card-based gamble feature. The dealer reveals one card; you pick from four face-down cards. Beat the dealer and your payout doubles. You can repeat this up to 10 consecutive times, theoretically multiplying a single win by 1,024x. A special Joker card in the deck beats everything and can only be drawn by the player, never the dealer.
Here is where the math gets interesting. The average RTP of the Risk Game is 84%, which means the house edge on gambles is roughly 16%. Your expected value shifts dramatically depending on the dealer's revealed card: a dealer 2 gives you 162% EV, while a dealer Ace drops to 42%. From a strategy standpoint, I would only gamble against low dealer cards (2 through 5) and collect against anything 9 or higher. Playing every gamble blindly will erode your bankroll faster than the base game builds it.
Bonus Buy Options
Risk Game (Gamble Feature)
After any win, pick a card to beat the dealer. Win doubles each round, up to 10 consecutive times. A Joker card beats all others and can only be drawn by the player.
RTP: 84%
Volatility, RTP, and Max Win
RTP sits at 96.07%, which is average for the current market. Medium volatility is the official classification from Endorphina, though some testing suggests the slot can lean toward medium-high during extended sessions, likely because of the lack of frequent small bonus payouts. Without free spins or multiplier features to smooth out variance, dry spells may feel longer than comparable medium-volatility slots.
Maximum win is 3,000x the bet, achieved by filling all 100 paylines with Anubis symbols (30x per line). That ceiling is modest by 2024 standards. For a medium-volatility profile, I would expect somewhere in the 2,000x to 5,000x range, so 3,000x lands right in the middle. The Risk Game can technically push individual wins higher, but its 84% RTP makes sustained doubling a losing proposition over time.
