Mystery Joker 6000 is a classic-style slot by Play'n GO, released on 20 Dec 2017 on a 3x3 grid with five paylines. Volatility is high, stakes run from 0.1 up to a listed £100.00 maximum, and the return depends heavily on how and where you play it: the top RTP version is published at 96.97%, a lower version at 94.21%, and the game's Super Meter mode carries a published figure of 100.95%. This review walks through the layout, the Super Meter, and those return figures - using only numbers we could verify.

Theme and symbols: a deliberate throwback
The look is a clean modern take on the fruit machine: a 3x3 window, classic symbols, and the joker as the character that gives the game its identity. Amusingly, the studio's own page files the theme as Food while operator lobbies list it under Classic and Fruits - a reminder that even basic catalogue data differs between pages, which is exactly why this site quotes figures only with a verified source. The symbol set is small and readable, which is the point of the format: you learn the whole game in a few spins.
How the game plays: five paylines and the Super Meter
Base play is as simple as three-reel slots get: five fixed paylines across the 3x3 grid, wins forming from matching symbols. The layer that separates Mystery Joker 6000 from a plain fruit machine is Super Meter mode - a higher-gear state where winnings can be gambled upward and where the published return figure is different from the base game. Classic-slot fans will recognise the high-low rhythm; readers comparing options on this site can also look at mega joker and joker pro slot for other takes on the joker character.
What the Super Meter figure actually means
The Super Meter mode carries a published RTP of 100.95%, against 94.21% in the base game of the same build. A figure above one hundred per cent looks startling, but read it correctly: it applies only to money cycled through that mode, you must first win in the base game to get there, and the combined session return is still governed by the version the casino runs. It is a genuinely interesting piece of game design - not a loophole. Treat the figure as what it is: a theoretical long-run average for that mode only. It does not predict any individual session, it is not a strategy, and it never turns the game into a positive-expectation proposition overall.
RTP versions: which one are you playing?
Two versions of the game circulate: a top RTP version published at 96.97% and a lower version at 94.21% - a discrepancy that independent catalogues such as great.com flag explicitly. Operators choose which build they run, and the page you are reading at any casino rarely says which one you have in front of you. The in-game information screen is the authoritative place to check - open it before you play, because the difference between those two figures is real money over any long session. The same advice applies across the whole catalogue of joker slots, and it is the single most useful habit a slots player can build.
Stakes: from 0.1 to the listed maximum
The minimum stake is listed at 0.1 and the maximum at £100.00, a range that covers careful bankrolls and high rollers alike. One recorded figure worth knowing for scale: the biggest win listed on an operator page we verified stands at £8,946. High volatility means the game pays in bursts - longer dry spells, larger hits when they land - so size your stake for the swings rather than the average.
Where to play the Mystery Joker 6000 demo
Play'n GO hosts the official free demo on its own site, playngo.com; third-party catalogues including casino.guru, slotstemple and great.com also list free-play versions. In Great Britain, free-to-play demos require age verification before you can spin - a regulatory requirement, not an operator quirk - which is why we do not embed the demo here.
Where UK players find it
In the UK the game appears in the lobbies of UKGC-licensed operators - Slingo and Spin Genie both carry it at the time of writing. Availability changes with operator catalogues, so treat any list as a snapshot rather than a promise.
How it compares with other classic joker slots
Within the classic three-reel family, Mystery Joker 6000 sits between the stripped-back originals and modern feature slots: the format is deliberately traditional, while the Super Meter and the published specification give it a contemporary edge. Our separate reviews of mega joker and joker pro slot cover the other directions the joker theme has taken - each game has its own verified specification page, so compare the figures there rather than relying on memory. The defining choice here is format, not theme: this is the one to pick when you want the fruit-machine rhythm with a published specification you can verify.
What we like
- Super Meter mode with a published 100.95% return on cycled winnings
- Simple 3x3, five-payline layout that takes a minute to learn
- Wide stake range from 0.1 up to a listed £100.00
- Studio publishes the game openly, so key figures can be verified
What to keep in mind
- Two RTP versions in circulation (96.97% and 94.21%) and casino pages rarely say which is live
- High volatility suits patient bankrolls, not short sessions
- Classic format offers no free spins rounds or bonus variety beyond the Super Meter
Our verdict
By the criteria we publish - transparency of the provider's figures, availability of an official demo, clarity of the mechanics and how fairly the game communicates its own rules - Mystery Joker 6000 scores strongly. The specification is published and checkable, the demo lives on the studio's own site, and the one caveat is the industry-wide one: confirm which RTP version your casino runs before you judge the numbers. As a modern classic slot, it does exactly what it promises, and the Super Meter gives it a reason to exist beyond nostalgia.

Frequently asked questions
What is the RTP of Mystery Joker 6000?
Two versions are published: a top version at 96.97% and a lower version at 94.21%. Separately, the Super Meter mode carries a published figure of 100.95%, which applies only to winnings cycled through that mode. The in-game information screen shows which version a specific casino runs.
What is the Super Meter mode?
A second playing state where base-game winnings can be played at a different gear. Its published return of 100.95% makes it the mathematically stronger use of the same money, but you reach it only by winning in the base game first.
What are the minimum and maximum bets?
The minimum stake is listed at 0.1 and the maximum at £100.00. Operator configurations can differ, so confirm the range in the lobby you play at.
Is there a free demo of Mystery Joker 6000?
Yes - the official demo is hosted on the studio's own site, linked from this page. In Great Britain you must pass age verification before demo play; that is a regulatory requirement.
Is Mystery Joker 6000 good for beginners?
The 3x3 grid with five paylines is one of the simplest formats available, so it is easy to learn. The high volatility, however, means swings are larger than the average modern slot - start at the low end of the stake range.
