This brand new slot game from NetEnt features a cast of somewhat hapless Brothers, who have a daily task of working their way deep into the Diamond Mine in the hope of making a discovery that will make them rich. The Boom Bothers slot is a five reel, 20 payline slot featuring 3D graphics, loads of bonus features and a decent payout structure.

How to Play Boom Brothers

A small animated video clip will introduce you to the Boom Brothers slot machine and once over you can settle down and choose one the several  options to begin play. The first option is the coin value which are: 0.01, 0.02, 0.05, 0.10, 0.20, 0.50 and 1.00. Next you will need to choose the number of pay lines. The Boom Bothers slot allows up to 20 playable lines, and the number of coins you wish to play on each line can be adjusted from one to five.

The game is equipped with the skill stop button, an auto-play feature as well as a speed option. The speed feature is mainly for players that have an older computer and find lag in NetEnt games. The lag is caused by the graphics and when you use this feature to reduce the graphics, the game will speed up.

The auto-play feature will allow you to play the game based on a certain number of spins, or you can set it to stop once a bonus feature is triggered.

Boom Brothers Slot Machine Features

This game offers multiple bonus rounds including a free spins feature and a railway secondary bonus.

Boom Brothers Free Spins - To win the free spins all you need to do is to spin in at least three of the Scatter Free Spins symbols. Once this is done,  the symbols will spin again and award you with a fixed number of free spins. The minimum number of free spins awarded in this game is 8, while the maximum is 50.  All wins occurring on the free spin bonus round will have a 3 x multiplier.

During this round you can win extra free Spins by spinning in additional free spin scatter symbols anywhere on the screen. For each one that spins in you are given one extra free spin. The scatters will only ever appear on reels 3, 4, and 5 during this bonus round.

You could also trigger any of the following two additional bonus games when playing either the base game or the free spins round, and both can payout some decent amounts of cash.

Boom Brothers Railtrack Feature - You will be awarded the Railtrack Feature when you spin a Rail Track symbol reels one, two and three then.

The reel symbols will then form themselves into a rail track and reels four and five will spin. The aim of the comical feature round is to complete this rail track on reels four and five so that some dwarves (yes dwarves!) can make it across the track. If this is done then an instant 4 x multiplier bonus payout is awarded and you then progress through to the bonus game.

Should a completed Rail Track not be formed, then the bonus game will not trigger and a consolation bet of 3 x your stake level is awarded.

Boom Brothers Rail Track Bonus - Once this bonus game is awarded via the Rail Track Feature above then you play a simple picking game built around a Mining Cart. The object of the game is to pick one of the three Dwarves Carts to reveal their contents. The contents of the box will be either diamonds, rubies or gold, and you will be rewarded with your prize depending on which one you pick.
