Mega Joker is NetEnt's classic fruit-machine slot with 5 paylines, a Supermeter bonus mode and one of the most quoted - and most misunderstood - RTP figures in the business. The provider publishes a return range of 85.28% to 99.00%, with a maximum payout of 200 x bet in the regular game and stakes running from €1.00 to €10.00. The celebrated 99% is real, but it is conditional on how you use the Supermeter, and careless play can push the return far below the headline. This review explains the mechanics, the paytable structure and exactly when each published figure applies.
Mega Joker slot at a glance
The verified specification: a NetEnt fruit machine with 5 paylines, an RTP range of 85.28% to 99.00%, high volatility, a hit frequency of 17.00%, a 200 x bet maximum payout in the base game and a 2000-coin ceiling in Supermeter mode. Stakes run from €1.00 to €10.00. The provider's own catalogue lists a release date of 01-10-2008, while other catalogues date the wide online release to 2013 - the game genuinely is that old, which explains its deliberately retro design.

How the Supermeter mode works
The Supermeter is the heart of Mega Joker: after a winning spin on the lower reels, you can move your winnings up to a second reel set and replay them at a higher intensity instead of banking them. The maximum win in Supermeter mode is 2000 coins, and while you are up there a joker landing on the middle reel awards a mystery win of between 100 and 2000 coins. The choice - bank your win or gamble it through the Supermeter - is made on every winning spin, which makes this one of the few classic slots where the player's decisions genuinely shape the long-term return rather than just the pace of play.
The 99% RTP: when it is real and when it is not
The provider publishes a return range of 85.28% to 99.00% for Mega Joker, and the top figure is only reachable through committed use of the Supermeter at full stake. Play it as an ordinary slot and you sit toward the lower end of the range; reduce your bet to just 1 coin per spin and the return drops to a dismal 76.9% - materially worse than almost any modern slot. In other words, the famous 99% is not a property of the game, it is a property of one specific way of playing it.
Symbols and game structure
The symbol set is pure fruit machine - classic fruit and bar-style symbols with the joker on top - arranged on a compact grid where the lower reels feed the Supermeter above. One honest caveat: the per-symbol payout values are not published in the sources we could verify, so we do not list them here - the in-game paytable screen shows the authoritative values with your stake applied. What is verifiable is the structure: regular fruit wins on 5 paylines in the base game, boosted wins and the joker's mystery award of 100 and 2000 coins at the extremes in Supermeter mode.
Does Mega Joker have free spins?
No. Mega Joker has no free spins round, no scatters and no multiplier trail - the Supermeter and the joker's mystery win are the only features. That is typical of its fruit-machine generation and part of the appeal: every spin resolves immediately, and the only decision is whether to bank or gamble through the Supermeter. If you specifically want a modern joker game instead, see our review of Mystery Joker 6000.
Where to play the official demo
The official free demo lives on the provider's own pages. In Great Britain, free-to-play demos require age verification before you can spin - a regulatory requirement rather than an operator quirk, and the reason we do not embed the demo here.
Graphics, sound and the retro feel
Mega Joker looks and sounds like the pub machine it imitates: a static cabinet frame, chunky fruit symbols, mechanical reel clicks and a short jingle on a win. There is no cinematic intro and no animation set-pieces, and that is clearly a choice rather than a limitation - the game predates the modern video-slot era and trades on exactly that nostalgia. If you judge slots by production values it will feel spartan; if you judge them by clarity, everything on screen means something.
Not to be confused: the other Mega Joker
A second slot with the same name exists from a different studio, Novomatic, and search results routinely mix the two up. This review covers the NetEnt game - the one with the Supermeter and the published 85.28% to 99.00% range. If the game in front of you has no Supermeter stage above the main reels, you are looking at the other Mega Joker, and none of the figures on this page apply to it. Checking the provider logo in the game client settles it in seconds.
Stakes and who the game suits
Stakes run from €1.00 to €10.00 - 1 to 10 in the coin terms the game itself uses - which is a narrow range by modern standards. Combined with the RTP mathematics, that shapes the audience precisely: Mega Joker suits deliberate, full-stake players who understand the Supermeter and want the top of the published range, and it actively punishes casual minimum-bet spinning. Players who want flexible small stakes may prefer a modern title instead - see our review of Joker Pro slot.
What we like
- Published RTP reaches 99.00% - the top of the range is genuinely documented by the provider
- Supermeter mode gives the player real decisions, not just a spin button
- Provider publishes its figures openly, including hit frequency of 17.00%
- Honest, readable fruit-machine design with nothing hidden
What to keep in mind
- The return is a range, not a number: 85.28% at the low end, and 76.9% at a 1-coin bet
- No free spins or modern features of any kind
- Narrow €1.00-€10.00 stake range
- High volatility plus a strategy-dependent RTP makes it easy to play badly without noticing
Our verdict
By the criteria we publish - transparency of the provider's figures, availability of an official demo, clarity of the mechanics for a newcomer and how fairly the game communicates its own rules - Mega Joker earns respect with reservations. The transparency is exemplary: NetEnt publishes the full return range, the hit frequency and the Supermeter ceiling, which is more than most modern releases offer. The reservation is clarity: nothing in the game itself warns a newcomer that the bet level and Supermeter decisions swing the real return across the whole published range, and a player who never reads a page like this one will probably play the worst version of the mathematics. A classic worth understanding before it is worth playing.
