More Rock-Themed Gridslot Action From Play’n GO, As the Black Mamba Slot Enters the Stage!

Unibet Casino has just added the latest rock inspired cascading gridslot from  Play’n GO slot titled Black Mamba to their casino which is yet another music collaboration slot, after the succesfull relases of House of Doom, Sabaton and Demon.

The Black Mamba slot is a 5×5 cascading wins grid slot which Play’n GO have a reputation for doing very well, based on the Italian band consisting of four members; Martina Cori (vocals), Alexandra Maiolo (guitar), Cecilia Nappo (bass) and Federico Maragoni (drums).

The band features heavily in the special features of this slot with musically themed mini-features triggering randomly along with a special Concert Feature where they all play out their special features one after another once the Charge Meter has been filled up for scoring special wins!

Other notable features to this slot are rising multipliers for each combo win scored on the grid, the 4 individual band member features that add a variety of modifiers including wilds and of course a free spins mode which is triggered when you manage to clear out the grid completely of symbols.

During the free spins mode, things can really heat up thanks to a locked-in Multiplier value earned from the base game trigger, lots more special features occurring on every spin, along with extra bonuses for clearing out the grid completely and the ability to trigger the Concert feature too during the bonus round.

Whilst the biggest wins do seem to be from the bonus round, the base game can throw out some nice wins also thanks to all the random features and particularly the Concert feature which adds all 4 into one spin!

Check out most of these exciting features in the gameplay video below!

Rising Multipliers

Each combo win that is scored in the game that creates a cascade of symbols will increase the multiplier value by 1 until the next spin.

Solo Features

Black Mamba Slot - Solo Features

The bands solo features will trigger randomly on any non-winning spin and have the following effects,

  • Fred’s Solo – Transforms a symbol into another symbol currently visible on the grid.
  • Cecilia’s Solo – Adds 1 to 2 Wild symbols on the grid.
  • Alexandra’s Solo – 2 lower paying symbols types currently on the grid are removed.
  • Martina’s Solo – The bottom row is cleared of all symbols except wilds and 1 high paying symbols can be converted in a 2x Wild.

Concert Feature

The Concert feature is triggered once you have filled up the special charge meter, this is done by scoring wins with the higher paying band symbols.

A further free spin is then awarded where all 4 of the solo features listed above will play out one after another on the grid giving you lots of chances to score wins and clear the grid.

Free Spins

Triggering the main free spins bonus round is done by clearing the whole grid of symbols and awards an initial 8 free spins.

During the bonus round Martina’s Solo activates after every free spin along with the band member that was currently activated in the base game when the bonus round was triggered.

You also start the bonus round with the currently achieved multiplier level from the base game trigger and this can increase also by scoring wins in the bonus round.

You can earn extra free spins during the bonus round by filling the charge meter earning between 2-4 extra spins depending on how much of the meter is filled, along with triggering the Concert feature during the bonus and earning a special 50x your bet award for clearing the grid!

Overall Opinions

The Black Mamba is another decent grid slot release from Play’n GO, if you are a fan of this style of cascading wins then you should enjoy this release as there is a nice balance of base game features, special concert features and of course the main free spins bonus round.

Our playtesting resulted in bonus round wins in the range of 30x stake to well over 300x stake, with plenty more potential, particularly if you start the bonus round with a higher multiplier value or earn extra free spins during the bonus round!

Whilst there is nothing totally groundbreaking in terms of special features that have been incorporated into this slot, as a standalone title we did find plenty of constant action that kept the base game interesting whilst waiting for the elusive full grid clear to get the bonus round triggered.

Definitely worth a play if you enjoy grid/cascading slots and want more of the same with a few new twists!
