The first things to notice about Boom Brothers are the graphics and animations which are top drawer. Rather than using traditional reels, Boom Brothers uses mineshaft link chains to get the symbols in the right places. The 3D imagery used in the bonus features is equally impressive. So Boom Brothers looks great. How does it perform as a potentially big-paying slot? Well rather well as it happens.
In addition to the 5 reel, 20 payline base game, Boom Brothers comes with a pair of bonus features. The Free Spins feature is triggered with the arrival of 3 or more Free Spins symbols which go on to spin and reveal a random number. These numbers are totted up and give a total of between 8 and 50 free spins. And that's not all as all winnings in the feature come with a 3x multiplier. You can get even more free spins during the feature itself, making bigger payouts possible.
The Railtrack feature which is triggered when railtrack symbols appears on reels 1, 2 and 3. The final 2 reels are then respun. If those reels complete the track, you'll receive a 4x multiplier and go to through to the Bonus feature. All is not lost if you don't complete the track as 2x and 3x multipliers are available depending on how many parts of the track are missing. You won't go through to the Bonus round if the track is incomplete though.
And what of the Bonus feature? You'll be taken to a new screen and greeted by the Boom Brothers who will be holding a diamond, ruby or gold. If your luck is in, up to 3x multiplier will be awarded. The selected brother will then take the 5 steps across the track to collect the cash prize. The diamond is the one to hope for as this is the biggest payer.
One final goodie to notice from the base game is the Second Chance feature where a non-winning spin can randomly trigger 1 of 4 second win chance features. It won't help you break the bank but it's a nice little extra. Since launching in 2010, Boom Brothers has become one of NetEnt's most popular slots and it's easy to see why. It looks fantastic and it plays well too.
If you're after something a little different to standard slots fare, Boom Brothers is a great place to start. Saying that, I considered to not be as volatile as I like my slots to be – Dead or Alive (also by NetEnt) is more up my street as well as land-based favourites like Where’s The Gold (by Aristocrat).
