Mega Joker RTP 

The game boasts an impressive RTP of up to 99%. This ranks it among the highest RTP slots available to play on any of the top online casino sites in the UK. However, keep in mind that this only applies to 10-coin bets. If you decrease your bets to just 1 coin per spin, the RTP drops significantly to 76.9%.


The Mega Joker slot offers high volatility, making it quite unpredictable and potentially rewarding you with the chance of significant wins.

Hit Frequency

In games with higher volatility like NetEnt’s Mega Joker slot, predicting hit frequency becomes a bit more challenging. Hit frequency refers to how often players can expect to win.

Jackpot & Maximum Win

The maximum win achievable in Mega Joker is 2,000 times your initial bet.

Mega Joker’s High RTP & Volatility

One of Mega Joker’s highlights is its high RTP. However, its high volatility adds an element of unpredictability. With a maximum win of 2,000 times your bet, it’s slightly lower compared to many contemporary slots.

Game Features

Let’s delve into some key features of Mega Joker that distinguish it from other online slots.

NetEnt’s Mega Joker Slot Supermeter

The standout feature of NetEnt’s Mega Joker slot revolves around its Supermeter. If you’re familiar with its counterpart Jackpot 6000, you’ll recognize it. After a win, you have the option to either collect your winnings or enter Supermeter mode.

In this mode, the upper reels spin instead of the lower ones. If the joker appears in Supermeter mode, you’ll win an extra mystery prize ranging from 100 to 2000 coins. Apart from this, there are no other significant bonus features, reflecting its status as an older game.

Mega Joker Jackpot

Another exciting aspect of Mega Joker is its local progressive jackpot, which triggers randomly. Around 3% of player’s bets contribute to this jackpot, and its current value is displayed at the bottom of the game screen. However, to have a chance at triggering this jackpot, players must be playing outside of Supermeter mode and at maximum bet.

Wilds, Re-spins, Multipliers

Unfortunately, Mega Joker lacks wild symbols, free spins, or multipliers. Because the game aims to replicate the classic three-reel slot experience, these features are absent.

Mega Joker’s Main Bonus Feature

The Supermeter mode stands as the primary bonus feature with NetEnt’s Mega Joker slot. Unfortunately, unlike modern slots, it doesn’t include other common features like wilds, scatters, or re-spins.

NetEnt’s Mega Joker Slot Graphics & Sound

The game is set in what looks like a casino room, displaying the entire slot machine on the screen. Sound effects accompany reel spins, but there’s no background music or additional sound elements. As such, the sound setup is very basic. While you can play Mega Joker slot on your mobile device, it’s not optimized for mobile. In all honesty, this results in slightly compromised gameplay.

Mega Joker’s graphics are really starting to show their age and don’t stack up well against modern slots. Although it’s not unattractive, it no longer wows players. Some may find it cluttered, as the top and bottom reels could initially be confusing.

Troubleshooting Tips

To ensure smooth gameplay, we sugest that you keep your browser and plugins up to date. This reduces the chances of crashes or issues. If a game loads slowly or encounters problems, refreshing the page and checking your internet connection can help. If a game unexpectedly stops, the casino typically refunds any winnings accrued up to that point. Mega Joker Slot Verdict

While the NetEnt’s Mega Joker slot has been a favorite for many years, its age is becoming evident. Apart from the Supermeter feature and local jackpot, it lacks the additional features commonly found in more modern slots. Graphically, it doesn’t hold up as well as it once did. Players accustomed to modern slots may find Mega Joker to be somewhat dull. However, there remains a sizable audience that appreciates what Mega Joker offers. We think that its exceptionally high RTP undoubtedly contributes to its enduring popularity which is why players still flock to play it at King Billy Casino.

Play Another Slot Like Mega Joker

If you’re fond of Mega Joker, you’ll likely enjoy its counterpart, Jackpot, 6000. These games share many similarities, including symbols and the Supermeter function. According to online casino news in the UK, in some respects, Jackpot 6000 may even be a better choice over Mega Joker. Its layout is less cluttered, and the gameplay feels more enjoyable.
