Where to Play Mega Joker Slot Online
Mega Joker Slot Review
NetEnt’s Mega Joker is a classic release that brings back the look and feel of traditional pub fruit machines. The slot uses a simple 3×3 grid with five paylines, keeping gameplay straightforward and easy to follow. You’ll find it at many top-rated slot sites in the UK, with retro symbols such as cherries, lemons, and jokers that add to its appeal.
The Mega Joker slot reveals its biggest rewards in the Supermeter mode, which unlocks after a winning combination is formed in the base game. Landing three identical symbols on one of the active paylines creates a win, which can either be collected or moved into the Supermeter. Choosing to play in this mode increases your stakes and gives you a chance at bigger prizes.
The RTP rate is 99%, which is one of the highest in online slots. It’s a high volatility game, so dry spells are common, but payouts tend to be larger when they land. With a hit frequency of 16.52%, you’ll see a win roughly once in every six spins. The max win is capped at 2,000 coins, but an external and progressive jackpot can potentially award higher prizes.
The Appeal of Mega Joker: Why Players Love It
This classic NetEnt title has kept its appeal over a decade after its release. The reasons the Mega Joker slot machine remains a favourite include:
- High RTP: With a return to player of 99%, the game ranks among the top five slots for RTP in the UK.
- Classic Design: The 3×3 grid, fruit symbols, and the classic Joker resemble those seen on traditional slot machines you’ll find in land-based casinos.
- Progressive Jackpot: The game includes a progressive prize that grows with each bet until it is triggered at random.
- Supermeter Mode: This optional feature gives you a chance of increasing your payouts, but can also lead to the loss of your original prize.
- Available in Free Mode: The Mega Joker slot demo allows players to try the game without staking real money. You can access demo versions at many top-rated UK casino sites, including the ones we feature.
How to Play the Mega Joker Slot Game
Playing Mega Joker is easy to play, even if you’re still learning how to play slots. We’ve broken down the steps so you’ll know what to do.
-
Step 1: Choose a Casino Site
Find a trusted UKGC-licensed site, whether it’s an established name or a new slot site, that hosts the game and launch it. -
Step 2: Set Your Wager
Choose a bet size by clicking on the value of the coins on the bottom right of the game. Stakes start from 10p per spin and are capped at £5 under UKGC rules aimed to promote responsible gambling. -
Step 3: Spin the Reels
Now, tap the ‘Spin’ button and watch the reels spin. You’ll automatically receive a payout when three matching symbols appear on a winning payline. -
Step 4: Collect or Play in Supermeter Mode
When you land a win, the Supermeter feature is automatically activated. You can choose to collect your winnings at this stage or play them in this feature for higher stakes. While payouts range between x100 and x2,000, there’s also the chance of using up your original win.
Understanding Mega Joker Slot Payouts
Mega Joker features seven fruit machine symbols, including cherries, sevens, and jokers. To receive a payout, three or more matching symbols must land on one of the five winning paylines. Additionally, multiple wins across different paylines are added together, both in the base game and in the Supermeter feature.
Base Game Payouts
Bets in the base game are fixed at 10 coins per spin, and the total stake depends on the coin value you choose. The table below shows the payout in coins, which are then multiplied by your base stake.
Symbol/s | 3 Matches |
Cherries | 20 |
Lemons | 20 |
Watermelons | 80 |
Bells | 200 |
Treasure Chests | 2,000 |
Joker | A mystery win between 20 and 400 coins |
Supermeter Mode Payouts
Because the paytable changes once you’re playing in the optional Supermeter feature, the game comes with a second paytable. In this mode, wagers can be 20, 40, 100, or 200 coins. In turn, this determines the size of your winnings. Instead of fixed payouts, jokers provide a random win that can reach up to 2,000 coins per joker.
Symbol/s | 3 Matches with 20 Coins | 3 Matches with 40 Coins |
Cherries | 100 | 200 |
Oranges | 100 | 200 |
Grapes | 200 | 400 |
Lemons | 200 | 500 |
Watermelons | 500 | 1,000 |
Bells | 600 | 1,200 |
Sevens | 800 | 2,000 |
Joker payouts in Supermeter are:
- 20 coins: Three jokers on a payline trigger a mystery win of up to 1,000 coins
- 40 coins: Three jokers on a payline trigger a mystery win of up to 2,000 coins
- 100 coins: Three jokers on a payline trigger a mystery win of up to 2,000 coins. Additionally, one joker anywhere on the middle reel awards a random win between 100 and 2,000.
- 200 coins: One or more jokers anywhere on the reels results in a mystery win ranging from 100 to 2,000 coins per joker
Bonus Features in Mega Joker Slot
Unlike many modern slots, Mega Joker does not feature extras like free spins, wilds, and tumbling reels. Instead, this game delivers a classic slot experience with straightforward gameplay and simple payouts.
The Mega Joker slot machine comes with two primary bonus features. The main one is the Supermeter mode, which gives players the chance to stake their winnings in exchange for the potential of higher prizes.
Additionally, slot players will find a progressive jackpot. Available only in the base game, this prize increases gradually with each real-money wager until it is randomly triggered. Some casinos are home to no-wagering free spins promotions on your first deposit, giving you extra chances to explore this NetEnt game.
Mega Joker Slot RTP & Volatility
Mega Joker’s RTP can reach up to 99%, which is well above the return rates offered by most modern slots. However, the game uses adjustable Return to Player rates that range between 76% and 85%. To reach the 99%, you need to play with 10-coin bets in the base game or move your winnings into the Supermeter mode.
The Mega Joker slot has high volatility and a 16.52% hit frequency. This means that you can expect a win every six spins on average, so dry spells are common. The risk level is higher when compared to low volatility slots, but payouts are typically larger when they land. Players can win up to 2,000 coins on this classic slot game, while the jackpot offers the chance for further prizes.
Mega Joker Slot Demo & Free Play
Trying this retro slot in free play is the best way to explore how it works without tapping into your real-money bankroll. The Mega Joker slot free play version works exactly like the real-money one, except you’ll be playing with an imaginary balance. Additionally, you can understand how winnings carry over between the Supermeter and base game.
Comparing Mega Joker Slot to Other Popular Slots
While most online slot machines highlight bonus rounds, free spins, and dynamic graphics, Mega Joker delivers a more nostalgic experience. Its standout features are its high RTP, the Supermeter mode, and its progressive jackpot. In the table below, we’ve placed it among other slots in the UK to see how it compares.
Online Slot Machine | RTP | Max Win | Volatility | Free Spins |

Top Tips on How to Win on Mega Joker Slot
Like all slots, Mega Joker is a game of luck, and there are no guaranteed ways to ensure a win. However, keeping the following tips in mind can help you play it more strategically.
-
- Play with 10 Coins: The Mega Joker slot offers its high 99% RTP when playing with 10 coins per spin.
- Understand Supermeter Mode: Although the Supermeter may result in increased payouts, it also puts your original winnings at stake. So, decide if you’re ready to risk your earlier payout and don’t use it on every win.
- Try the Demo Version: Playing the Mega Joker free slot gives you the chance to understand whether you enjoy the game and get a first-hand feel of its features, RTP, and volatility.
- Take Advantage of Casino Promotions: Many platforms offer casino bonuses, such as welcome promos, no-deposit free spins, and loyalty rewards. Redeeming these gives you additional opportunities to spin the reels.
- Set a Budget: Set time and financial budgets before you start playing and stick to them. This helps you enjoy the game and gamble safely, without stressing about overspending.
Do We Recommend the Mega Joker Slot?
Mega Joker has held its ground for over a decade, thanks to its retro fruit machine design and signature Supermeter mode. Additionally, the progressive jackpot adds another dimension to the three-reel slot. With an almost unmatched 99% RTP and a potential win of 2,000 coins, it stands out from many other slots.
However, the graphics are better suited to players who enjoy a classic slot experience. Those who prefer modern visuals and feature-rich games may find it less appealing. Overall, we enjoyed revisiting the Mega Joker slot when writing this review, thanks to its straightforward mechanics, retro design, and classic symbols.
