Black Mamba

If the Black Mamba slot doesn’t ring any bells with you, you’re not alone. Some quick research helped us learn about this head-bang-worthy Italian rock band, which forms the theme for Play’n Go’s highly volatile new rock slot. And though you may not be familiar with Black Mamba’s tunes, they’re catchy enough to want to keep playing and listening… or at least that’s what we thought when we did this slot review.

Black Mamba Bonus features

The Black Mamba bonus features are quite involved, and there’s much going on in this rockin’ new slot to keep you occupied. One of the main Black Mamba features to note is the gameplay itself, which comes in the form of cluster pays on a grid. Instead of regular paylines, you’ll be awarded a win whenever three or more matching symbols appear adjacently from each other.

With every win that occurs, the winning symbols will be removed from grid to make way for new symbols and potentially a win from the same spin. Whenever this happens, you’ll also see the win multiplier increase by 1x, giving you the chance to bring in higher prizes.

That’s just the beginning of the features, which we’ll go through now in more detail.


There are actually two types of wilds in Black Mamba: the regular wild band logo, and the vocalist Martina Cori symbol, which will award a 2x multiplier for every win it completes.

Scatter symbol

There isn’t a scatter symbol in this slot, but don’t worry – there’s still a free spins round that can be activated in other ways.

Free Spins

If you manage to clear the grid of all symbols by landing a huge cluster pay, you’ll trigger the Black Mamba free spins, no deposit needed. This will award several free spins where you’ll either win a prize or see one of the band members appear to award a modifier on a losing spin. The Black Mamba free spins round is retriggerable too, allowing you to win up to an extra four spins each time.

Bonus Game

Any wins landed with a band member symbol present will help to fill up the Charge Meter on the side of the reels. There are six sections to fill up in total, but once you’ve filled it up by four, you’ll see the Concert feature come into play. Here, you’ll be awarded extra multipliers on your wins, along with random modifiers from the band members.

Other features

Like any good rock band, there are four members in Black Mamba, and each of them can apply a random modifier to any losing spin. The modifiers are:

  • Cecilia: Adds one or two wilds to the reels
  • Fred: Transforms one set of symbols into another to increase your winning chances
  • Martina: Removes the bottom row of all symbols except wilds and adds a high-paying Martina symbol to the reels
  • Alexandra: Demolishes two sets of symbols to make way for higher-paying symbols

Black Mamba Jackpot

Black Mamba is not a jackpot slot, so there’s no one big payout to play for. However, despite no Black Mamba progressive jackpot, you will have the chance to play for prizes of up to 5,000x per spin.

RTP and Volatility

The Black Mamba return to player of 96.5%, along with the high volatility makes this slot quite a lucrative one. The big wins might not come in very often, but the Black Mamba RTP ensures that when they do, they come in quite high.

Bonus Spins

We can’t make any guarantees, but casinos like Mr Green and LeoVegas are known to hand out bonus spins on their latest slots. So if you’re hanging out for Black Mamba bonus spins to take it for a test drive, we recommend subscribing to emails at these casinos.

Black Mamba Mobile

Just like you’d listen to Spotify on your mobile, you’ll also be able to play Black Mamba’s slot from your trusty device since Play’n Go has conveniently optimised the slot for this platform.
