Boom Brothers is a slot machine made by Net Entertainment. First of all, I'd like to start off by saying that this could have been a really cool slot machine, but that they have made some major mistakes from a slot players view. One example of this, is Boom Brothers re-spin feature. During this feature one or more reels can get a re-spin after the reels have stopped for the first time, but the problem is that the slot might re-spin a wheel where there’s no possibility to win when the reel stops. If we try to look at the more positive side, Boom Brothers has a free spin feature with a x3 win multiplier and a bonus game where it's possible to win up to 500x the stake per spin. It also has a quite cool theme from a diamond mine where bombs and precious metals plays a big role. The maximal potential win on this slot machine is won by getting 5 wild symbols on a payline in the free spins, this combination would pay a prize of 1.125x the total stake. The theoretical payout percentage for Boom Brothers is at the normal for Net Ent games at 96.40%.

Game features


Boom Brothers has wild symbols on all the reels, these symbols substitute for all symbols except the Free Spins and the Railtrack symbols. A 5 of a kind combination of them on a payline will pay 375x the stake during the base game, and 1.125x the stake during the free spins. Boom Brothers has no less than 4 different second chance features. Those second chance features can't pay you much, but Boom Brothers also has a bonus game and a free spin feature, so bigger wins might wait for you there.

Second Chance features: There are 4 different second chance features and all of them can randomly appear after any spin in the base game or during the free spin feature. The first feature is when one of the brothers comes walking with a trolley below the reels, he can put TNT barrels on one or more of the reels, the reels will then explode and get 1 re-spin. The second feature is a flying brother that spins one or more symbols around to turn them into another symbol. The third option is a brother that pops up on the screen and re-spins 1 to 3 reels. The last second chance feature is a brother that throws sticks of dynamite on some of the symbols, these symbols will explode and turn into wild symbols. Like I said in the beginning of this slot review, these second chance features might feel completely useless since some of them might activate without giving you any win.

Bonus game: The first part of the bonus game can be triggered from both the base game and the free spins. It's triggered when a Railtrack symbol lands as a 3 of a kind combination from left to right on an active payline. This combination will not activate the bonus, but a chance to get into it. The 3 first reels will then have formed a railtrack, but you need a railtrack symbol on both reel 4 and 5 to continue. This is possible to get in a round where you get 2 spins for reel 4 and 5. During these spins, there's only railtrack symbols or no symbols on the reels. If you manage to land the 2 needed rail tracks during the two spins, you move on to the bonus game, if not you return to the base game.

In the main bonus you stand in front of 3 different brothers and rail tracks that has a prize in the end. There's one gold bar that pays a prize from 7.5x to 25x the stake, there’s also a red ruby that pays 12.5x to 50x the stake, and the grand prize is a diamond that pays from 20x to 500x the total stake. 5 rail tracks are needed for any of the brothers to reach their treasure. 3 trolleys will appear on the bottom of the screen and you get to pick one. Each of the trollies either has a gold bar, a red ruby or a diamond. Each of them will have a value of 2 or 3 steps toward the prize. After a pick, new trollies will appear with the same values hidden. The first brother that reach to the end of the prize, will rewrad you with anything between the lowest and the highest posible prize.

Free spins: The free spins are triggered with 3 or more Free Spins symbols placed anywhere on the reels. Each of the symbols will then reveal a number, and these numbers will be added together to show your total amount of free spins won. With other words, the more symbols that trigger the feature, the more spins are available to be won. The minimum amount of spins is 8 while the maximum amount is 50. During the free spin feature, an additional spin will be won for each Free Spin symbol that appears. All wins during the free spin feature are multiplied with a x3 multiplier. It's not possible to re-trigger the free spin feature.
