For German players the appeal is that return figure. The trade-off is that the 99% only applies when you play through the Supermeter at the higher coin levels, and the game is deliberately old-fashioned: fruit and bell symbols, no wild, and no bonus round to trigger. It rewards a specific way of playing rather than a lucky spin. Players who grew up with pub fruit machines will recognise the format straight away. The summary below sets out the core numbers before we walk through how each part works.

How to play Mega Joker
Mega Joker is played in coins. Set your coin value and the number of coins per line, then spin the lower reel set, which is the main game. Wins pay along the 5 paylines from the left, and the paytable is short - fruits, bells, a star and the Joker. After any win you choose to collect it or move it up to the Supermeter, the second reel set above, where the higher payouts and the jackpot chance live.
On German-licensed sites the stake is capped at €1 per spin, autoplay is switched off and a minimum spin time applies under the current gambling treaty. Because the top RTP depends on playing through the Supermeter at higher coin levels, that €1 cap changes how the game plays compared with the global version. There is no wild symbol and no scatter - the value sits entirely in the Supermeter and the Joker.
Mega Joker rules
The paytable is classic fruit-machine fare, led by the Joker, then the star and bell, then the fruits. Values below show the shape of the table; exact figures can vary between casino builds, so check the in-game paytable before you play.
Symbols and payouts
| Symbol | Tier | Payout |
| Joker | High (premium) | Top payout and mystery win |
| Star | High | High payout |
| Bell | Mid-high | Mid payouts |
| Melon / Grapes | Mid | Mid fruit payouts |
| Cherries / Lemon / Plum | Low | Lower fruit payouts |
- Joker: the top symbol and the key to the mystery win in the Supermeter. There is no separate wild in Mega Joker.
- No scatter or free-spins symbol: the game has no bonus round to trigger - the Supermeter is where the extra value is.
Mega Joker bonus features
Supermeter mode
The Supermeter is the heart of the game. After a win you can collect it, or send it up to the second reel set and keep playing there at 20, 40, 100 or 200 coins per spin. The Supermeter reels pay more than the base game and are where the mystery win and the jackpot chance sit. The higher the coin level you play at, the higher the potential payouts - and it is this higher-stake Supermeter play that lifts the RTP toward the 99% headline. It also works as the game's gamble: winnings held in the Supermeter can be lost as well as grown.
Mystery Joker win
Landing Jokers in the Supermeter triggers the mystery win, a random award that can pay from a modest multiple up to the top coin prize. It is the main route to the largest non-jackpot wins in the game, and it only appears in Supermeter play, which is another reason the mode is central to how Mega Joker rewards you.
Progressive jackpot
Mega Joker carries a progressive jackpot that can be awarded at random, with a small share of each bet feeding the pool. Because progressive jackpots are restricted under the current German gambling treaty, the jackpot may not be offered on German-licensed sites - the game can be present without the progressive component. Check whether the jackpot is active at your casino before you rely on it.
Mega Joker on mobile
Mega Joker is built in HTML5 and runs in the browser on both iOS and Android, with no separate download or native app required.
- We tested on an iPhone 14 in Safari and a Samsung S23 in Chrome, on standard German 4G and home broadband.
- Both reel sets - the base game and the Supermeter above it - fit the portrait screen, with the collect and gamble controls clearly placed.
- The Supermeter switch and the mystery Joker win play out the same on a phone as on desktop.
- Load times were short on both devices - the game is a light file - and the retro artwork stays crisp on a phone screen.
Our take
Mega Joker suits players who value return above features and understand how to use the Supermeter. Its strengths are the up-to-99% RTP that ranks among the best in the market, the classic fruit-machine feel, the mystery Joker win and the progressive jackpot where it is offered.
The limits are worth being clear about. The 99% only applies when you play through the Supermeter at higher coin levels, so casual base-game play returns less. High volatility means the balance can swing hard, there is no wild, no free spins and no bonus buy, and the design is plainly dated. On German-licensed sites the €1 stake cap limits the higher Supermeter coin play, and the progressive jackpot may be absent. For players who want one of the highest-RTP slots and will play it the way it is built, it holds up; anyone after modern features or big multiplier wins should look elsewhere.

Player reviews of Mega Joker
- Lukas, Berlin (2026): "I play it purely for the RTP. You have to use the Supermeter properly - collect too early and you leave the good part on the table. Built a small win into a decent Supermeter run once."
- Anna, München (2026): "Old fruit-machine feel, no free spins, no wild. On the German licence the €1 cap limits the higher Supermeter coins, so it plays smaller than the global version. Still one of the best returns around."
- Jonas, Hamburg (2026): "The mystery Joker in the Supermeter is the highlight - got a random award that paid well above a normal line win. High volatility though, the balance moves fast."
- Sophie, Frankfurt (2026): "Played on my iPhone, both reel sets fit fine and it loads quickly. No jackpot showing at my German-licensed casino, so just the base game and Supermeter for me."
- Felix, Köln (2026): "Not a modern slot at all - no bonus buy, nothing to trigger. But the up-to-99% return is real if you play the Supermeter. I treat the mode as the gamble it is."
- Marie, Stuttgart (2026): "Simple and high-RTP. The Supermeter is the whole game and it is a risk feature, so it can go either way. Fair and honest for what it is, just check if the jackpot is even active."
