Mystery Joker by Play'n GO: headline RTP 96.98%, Medium volatility, max win x6 020.
An RTP of 96.98% means a house edge of 3.02% — the expected cost is 3.02 units per 100 staked over the long run, whatever a single session does.
Mystery Joker sits at medium volatility — a middle profile where wins are neither rare nor frequent enough to dominate a session.
The advertised ceiling is x6 020. Max win figures describe the tail of the distribution, not a realistic target: on most games with a ceiling this high the probability per spin is below one in a million.
We measured 2 different RTP builds of this game across casinos: 96.98% at the best and 96.98% at the worst, a 0.00pp spread. That is the same game costing meaningfully more to play at one operator than another, and it is the reason we track builds at all.
Against our catalogue the number is above the median of 96.13%, higher than 95% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
Stakes run from 0.01 to 20 per spin with fixed betways.

This title is tagged Joker. A theme is art direction, not maths — two games sharing every symbol can be priced differently.
Mystery Joker has a published RTP of 96.98%, a house edge of 3.02%. We measured 2 different builds across casinos, from 96.98% down to 96.98%, so the operator you pick changes the number.
Yes. Mystery Joker has a free demo with the same mathematics as the real-money version — the only thing that changes is that the balance is not yours. A demo cannot tell you the RTP build a particular casino serves.
Mystery Joker is a Play'n GO game, so the outcome is produced by the studio's certified RNG rather than by the casino, and it is not provably fair in the cryptographic sense — you cannot recompute a spin from a seed. What the casino does control is which RTP build it serves, and on this title we measured a 0.00pp spread between operators. That is the real variable, and it is measurable.
Of the operators we measured, Stake serves the highest build at 96.98%. The full per-casino table is on this page, and our RTP builds report explains how the measurement works.
