Game Review

Mega Joker Slot

NetEnt's Mega Joker is a surprisingly entertaining combination of a classic pub fruit machine and a Progressive Jackpot slot. The game looks exactly like a pub fruit machine, dusty plants included, and offers two levels of gameplay – standard spins and Supermeter spins.

While Supermeter spins hold the highest RTP and the largest winning spin values they are ineligible for winning the Progressive Jackpot. The game offers a surprisingly high RTP of 99% and the unexpected opportunity to win its Progressive Jackpot during any random spin.

Theme, Soundtrack and Symbols

To really delve into the fruit machine theme of the Mega Joker NetEnt designed the multi-level reels to emulate the machines perfectly you would find down at your local pub. It is set in a nondescript corner of a room flanked by dusty plants.

The reels are split into two distinct game screens with base game spins taking place on the lower 3x3 reels and the Supermeter spins on the upper 3x3 reels.

In keeping with the theme, all the symbols are their values are presented on the face of the slot machine. The base game spins use Treasure Chests as the highest paying symbols, followed by Bells, Watermelons, Lemons and Cherries.

Supermeter spins don't offer Treasure Chests opting to use green 7's as the top paying symbols. On both spin levels, the Jokers are special symbols paying out random big win amounts.

Mega Joker doesn't offer any background music; rather, the game uses classic bar machine reel sounds. With rolling sounds for collecting coins and exuberant jingles when you land a winning payline.

Game Mechanics

Mega Joker is a high variance slot machine that is played out across dual 3x3 reel sets. Both reel sets offer 5 fixed ways to win, making it an incredibly easy slot to learn.

It does, however, offer a surprising RTP of 99%, it is worth keeping in mind that this is during the Supermeter spins. The base game RTP is only 85%, but you end up play most of your spins in the Supermeter mode so its not that big of a concern.

The maximum line bet payout is an instant 200x bet when you land three Treasure Chest symbols on the reels. That's a fantastic return considering bets are either €1, €2 or €10. Winning €2000 on a €10 is nothing to joke about.

It is possible to win up to €2000 per line bet in Supermeter mode but there your bets can be as high as €200 per spin making it only 10x stake.

The Progressive Jackpot value in Mega Joker is smaller than most averaging between €30,000 up to €50,000. Again, your maximum risk per spin is a maximum of €10 during the base game.

Special Features

In keeping with the classic fruit machine theme of Mega Joker, the slot does not offer any Wilds, Scatters, Free Spins or Respins. It does, however, offer Supermeter Spins and a random Jackpot.

Supermeter Spins

Whenever you win you in the base game, you have the option to collect your winnings or use them to play Supermeter mode. In Supermeter mode, there are four predefined bet settings and the potential win amounts and Joker payout ranges, known as Mystery Wins, are set accordingly.

Progressive Jackpot

Unlike other Progressive slot machines where you first need to unlock a special feature to play for the jackpot in Mega Joker, the progressive is triggered at random during any base game spin. While Supermeter spins offer much higher rewards than the base game, there is no chance of triggering the progressive during Supermeter mode.

Play ‘On The Go’

NetEnt has optimised Mega Joker slot for all mobile devices. This includes mobile phones and tablets which run on Apple iOs, Android or Windows.

CasinoWow Game Verdict

With its high 99% RTP and low stakes per spins Mega Joker is definitely a must-play casino game for fans of fruit machines who want to the thrill of playing a Progressive Jackpot slot without having to break the bank.

At CasinoWow, you can try it out in free play mode so that you will be familiar with the game.
