Black Mamba


Black Mamba Slot Review

Black Mamba is a video slot from Play’n GO that is played in a 5×5 grid and comes with cluster wins. Released in November 2019, this game can be played at online casinos such as CasinoCruise, Vera&John or Guts.

Theme and general information

What is it with Play’n GO and basing their music themed slots on rock bands hardly anyone knows? Apart from Sabaton and House of Doom, who certainly have a bigger fan base, a lot fewer have heard of Demon and fewer people still have ever heard of Black Mamba. The game is based on an Italian rock band that has four members: bassist Cecilia, vocalist Martina, guitarist Alexandra and drummer Fred.

And that is about as much as we know. There is little to be found out online about this band, though you can visit their Spotify bio page for some details. Otherwise we recommend you just listen to their music to figure out whether you like them or not. Nothing else really matters anyway.

The game features the band’s music and all four members are also prominent on the reels and beside it. We get two wild symbols on the reels: the black mamba and Martina. The black mamba is worth 25x our stake and Martina pays out 50x our stake for five in a cluster. Fred, Cecilia and Alexandra each pay out 5x our stake in a cluster of 5. If you get a combination of the four band members you still get 3x our stake for such a win.

We also get four low-value symbols, which are worth between 1x and 1.5x our stake for a cluster of 5. Here we have microphones, headphones, a guitar pick and drumsticks with cymbals.

You can play this game from 0.20 to 100.00 per spin.

Four band members and four modifiers

We get a typical cluster pay slot from Play’n GO here. We play on a 5×5 grid and a minimum of three symbols aligning vertically or horizontally pay out a win. Additionally, the multiplier on the left-hand side climbs by 1x with each consecutive win.

On any non-winning spin, we may get a Solo Performance from one of the band members. Which one we get depends on which band member is currently performing on the right-hand side.

  • Alexandra – Removes two sets of symbols from the reels, which makes room for more symbols to fall in from above.
  • Cecilia – One or two wilds are added to the grid.
  • Fred – Transforms one type of symbol into another type of symbol.
  • Martina – Demolishes the bottom row of symbols, though not the wilds. If other band members are on the bottom row, they will transform into Martina wilds. The feature is only active during the concert feature and the free spins.

As with just about any other grid slot from Play’n GO, we get a charge meter to the left here as well. If band members are part of winning combo, the meter gets charged with each consecutive win. Four wins in a row will activate the Concert Feature. If the meter is overcharged, we get the multiplier carried over as well.

During the concert feature, each band member gets to perform their feature in turn,

Clear the screen to trigger the free spins

The free spins are triggered if you manage to clear the grid of symbols entirely (or if only one or two wild symbols remain). Now, on any losing spin, the band members will perform their features. Martina, however, will perform hers on every single spin.

A win multiplier is also applied, though it resets on a losing spin. However, it only resets to the multiplier that was carried over from the base game. It is possible to retrigger the free spins by charging up the meter on the left-hand side. You will receive 2 spins each time that happens. If you overcharge the meter, you get 4 spins instead.

Conclusion: A surprisingly entertaining slot even if you don’t know the band

The theoretical RTP (Return to Player) for Black Mamba is 96.50%, which is good. But the RTP can be adjusted down by casinos to 94.50%, which is not great. Also, the slot is very volatile, and you may have to budget carefully.

Black Mamba is surprisingly entertaining. It doesn’t matter that you may never have heard of the band. Perhaps the announcements in between are a little annoying here and there, but the music is not bad at all and the game is fun.

The maximum win is 5,000x our stake, though you are more likely to see between 100x and 500x your stake, with a little luck at least. Mostly, wins feel relatively frequent, but that doesn’t change that the game is volatile.
