Devil Joker Slot by Pragmatic Play

Gates of Olympus in a Devil Costume

Devil Joker runs the Pragmatic Play scatter pay formula on a 6x5 grid. Eight or more matching symbols anywhere on screen form a win. Winners vanish, remaining symbols drop, new ones fill in. Multiplier symbols land with random values up to 500x. When the tumble chain ends, all on-screen multipliers add together and multiply the total. If you've played Gates of Olympus, Sugar Rush, or any of the dozen-plus slots using this engine, you know exactly how this plays.

The theme: a devil girl with a trident, playing cards, dice, hearts, and spades. Red-and-blue lighting, fire at the bottom of the screen, a circus-like vibe. Card suit symbols fill the low-pay tier while themed icons (devil girl, crown, flames) handle the premiums. The top symbol pays 1,000 coins at maximum count.

Free Spins With 15 Starting Spins

Four scatters trigger the bonus round with 15 free spins - five more than the typical 10 you get in most GoO-style slots. Three scatters during the round add 5 more. Multiplier values persist across the entire bonus, building a progressive total. Every multiplier symbol that lands adds its value permanently.

Multiplier range runs from 2x to 500x. The higher values appear rarely, but even consistent small multipliers compound into meaningful totals over 15 spins. The five extra starting spins compared to the standard formula give more opportunities for multiplier accumulation, which is the single mechanical distinction this slot offers.

The RTP Question

95.50% return to player is the number that matters here. It's below the 96% industry average and well under what Gates of Olympus (96.50%) or Sweet Bonanza (96.48%) return. Over thousands of spins, that gap translates to noticeably faster bankroll erosion. Ante bet at 25% extra cost doubles scatter frequency and runs at the same 95.50%. Buy bonus is 100x.

Max win caps at 5,000x in normal mode, 4,000x with ante. Bets range from 0.20 to 240.00. The game works. The formula is proven. But the below-average RTP without any compensating innovation in the feature set makes this a hard recommendation when the original Gates of Olympus and its variants exist at better return rates.
