Mystery Joker series
The Mystery Joker series is Play'n Go's compact retro-fruit franchise, built on a 3x3, five-payline base that swaps bonus treatment between free spins and a wheel. Mystery Joker established the formula in 2014 with medium volatility, free spins, a scatter symbol and a listed maximum win of 6,020x.
Ranked by Slot Score
| Game | Year | RTP | Volatility | Slot Score |
|---|---|---|---|---|
 Mystery JokerPlay'n Go | 2014 | 93.99% | Medium volatility | 45 |
 Mystery Joker 6000LatestPlay'n Go | 2017 | 94.96% | Low volatility | 50 |
Mystery Joker 6000 retained the same reel layout and line count in 2017 but changed the reward rhythm. Respins and a bonus wheel replaced the original's free-spin emphasis, volatility moved to low, the listed maximum fell to 1,200x and the bet ceiling rose from 5 to 100. The original therefore carries the sharper payout ceiling, while 6000 favors lower volatility and more frequent interaction with its wheel-based bonus structure.
