Mystery Joker review
The single most important fact about Mystery Joker is not on the reels. Play'n GO's three-reel game from 2014 exists in five RTP versions, from 96.98% at the top to 83.99% at the bottom, and which one a site runs changes the cost of play more than any feature does. The game itself is simple: the Joker's hat is the scatter, free spins can end in a mystery prize, and volatility is Medium.
Five versions, very different costs
At the best setting of 96.98%, the house edge is 3.02%, or about $30.20 kept per $1,000 wagered. The other versions are 93.99% (6.01% edge, $60.10), 90.98% (9.02% edge, $90.20), 86.98% (13.02% edge, $130.20) and 83.99% (16.01% edge, $160.10). The lowest version costs over five times as much as the highest for the same play.
Over 100 spins at $1, the expected cost is $3.02 at 96.98% but $16.01 at 83.99%. At $5 the gap widens to $15.10 against $80.05, and at $0.20 it is $0.60 against $3.20. With a spread that wide, confirming which version is active matters before the first spin.
A three-reel game with a twist
Play'n GO pitches it as suitable for newcomers and long-time players alike. The studio's page describes three reels and a scatter in the shape of the Joker's hat. Three scatters unlock free spins, and during the round a mystery prize can be won. Landing two or three scatters inside the round adds more free spins.
The page does not say how many free spins are awarded, what the mystery prize can be worth or how wins are counted on the reels. No max win is published either. The character's name, the studio explains, comes from the fact that nobody knows what he looks like.
The 6000 edition and relatives
Mystery Joker 6000, from 2017, lists a 94.21% RTP and High volatility, so it is the swingier and costlier relative. Xmas Joker from 2015 shares the 96.98% top RTP and Medium rating. Gold Trophy 2 and Pearls of India, both from 2014, list 96.88% and 96.87%. Gemix, Enchanted Crystals and Golden Ticket, also 2014 releases rated Medium, list 96.83%, 96.72% and 96.69%.
Who should play it
A good fit for anyone who prefers a short rulebook and moderate swings, provided the 96.98% version is the one on offer. On a low-RTP version the same game becomes an expensive way to spend time. The free demo lets you see the free spins and the mystery prize without staking money.
Pros
- Simple three-reel design with free spins that can be extended
- Medium volatility
- Free official demo available
Cons
- Five RTP versions, the lowest at 83.99% with a 16.01% house edge
- No max win published
- Free spins count and mystery prize values are not described
Verdict
Mystery Joker is a simple three-reel game with Medium volatility, a scatter-triggered free spins round and a mystery prize. At its 96.98% setting the house edge is 3.02%, but the same game can run at 83.99%, where the house edge is more than five times higher. Confirm which version is running before you spin, and treat it as paid entertainment.
