A 6×4 fruit-machine throwback from Pragmatic Play with crown scatters carrying 2× to 25× multipliers and a 5,000× max win cap. Test the official demo below — no signup, no download.

Joker King is a 5/5 volatility slot built around scatter multipliers and a free spins round, not base-game wins. Bonus triggers roughly every 100–150 spins. The 5,000× cap is real but practically unreachable; 200–800× is the realistic ceiling on a strong bonus round.
Whenever a Joker Wild lands, he picks one paying symbol type at random and turns every instance of it on the grid into a Wild. Land more Jokers on the same spin and the same number of symbol sets get transformed. Wins are paid after the transformation.
Each crown scatter carries a random multiplier of 2×, 3×, 5×, 10× or 25× on landing. Multipliers from multiple scatters add together and apply to the total win on that spin. Six maxed scatters give a theoretical 150× combined multiplier — the math behind the 5,000× cap.
Three, four, five or six scatters award 8, 10, 15 or 20 free spins. During the round, at least one Wild lands every spin, so the transformation feature fires guaranteed. Three or more scatters during the round retrigger it — without limit.
Joker King ships at a default 96.5% RTP, slightly above the industry median of 96.0%. Pragmatic Play also offers operators two lower variants: 95.5% and 94.5%. Over 1,000 spins at $1 stake, the gap between 96.5% and 94.5% is roughly $20 in expected loss — small per session, meaningful over a year. Always check the in-game info panel before depositing; the RTP is listed near the volatility indicator. Volatility sits at the maximum 5/5 on Pragmatic's internal scale, which means base-game wins are rare and small (the longest paying line of any low symbol returns just 1× to 1.6× the bet for six matches), and the math is loaded into the bonus round and scatter multipliers.

Open the bet panel at the bottom right and choose any value between $0.25 and $125 per spin. The 25 paylines are fixed — you cannot adjust them. Bet sizing is the only lever you control.
Most regulated casinos run the default 96.5% build, but Pragmatic ships the slot in 95.5% and 94.5% variants too. Open the info panel (i) and scroll to the volatility/RTP section to verify before depositing.
Press the central button to spin manually, or hold space for turbo. Autoplay supports up to 100 spins with optional stop conditions on a single win or balance change.
When a Joker lands, a random paying symbol on the screen converts to Wild after the spin resolves. Wins are paid post-transformation. Crown scatters carry their multiplier visibly — you see the 2×, 5× or 25× before the round ends.
Three crowns hand you 8 free spins, four give 10, five give 15, six give 20. Inside the round, a Wild is guaranteed every spin, retriggers stack 8–20 more, and the 5,000× cap ends the round early if you hit it.
Joker King competes with three established joker-themed slots: Pragmatic's own Joker's Jewels (2019) and Ice Joker (2020), and Play'n GO's Mystery Joker 6000 (2018). Each takes a different approach to volatility, max win, and bonus features. The verdict below is built from official paytable data and tester sessions.
| Provider | Provider | RTP | Volatility | Max Win | Year |
|---|---|---|---|---|---|
| Joker King | Pragmatic Play | 96.5% | 5/5 | 5,000× | 2021 |
| Joker's Jewels | Pragmatic Play | 96.5% | — | 1,000× | 2019 |
| Mystery Joker 6000 | Play'n GO | 94.0% | — | 6,000× | 2018 |
| Ice Joker | Pragmatic Play | 96.5% | — | 3,000× | 2020 |
Short answer: Joker King is worth playing if you accept long dry stretches in the base game in exchange for a wild-replacement bonus that fires on every free spin. Skip it if you want frequent small wins or a bonus buy. The strategy below covers bankroll sizing, stake selection, and common mistakes — written for a 5/5 volatility slot, not generic slot advice.

No. Pragmatic Play did not include bonus buy in Joker King. The free spins round can only be triggered by landing 3+ crown scatters during normal play.
The win cap is 5,000× the bet. At minimum stake ($0.25) that's $1,250; at the $125 maximum, the cap is $625,000. The cap requires a near-perfect combination of full-screen wilds and 40× combined scatter multipliers.

Yes. The game is built in HTML5 and runs on any modern iOS or Android browser. The 6×4 grid scales correctly to portrait orientation, and turbo spin is supported via tap-and-hold on the spin button.
Pragmatic deliberately set low symbol values (orange and plum pay just 1× to 1.6× for six on a payline) to load the math into the bonus round. The wild replacement and free spins are where the math lives — base spins exist primarily to build to the trigger.
