How to play
Boom Brothers is a 5-reel, 20-payline title that comes with a coin value range of 0.01 to 1 coin. This translates to a min and max bet of 0.01 and 100 coins respectively. If you don't want to bet real money right away, there's a demo mode that could help. In this you'll get to know the auto-spin feature as well. This allows you to stop the game after a particular number of spins (up to 100 spins) or when any of the bonuses are activated. For the latter, the Wild and Scatter symbols are to look out for. Nonetheless, even the usual symbols shouldn't be ignored.
Starting with the highest valued symbols, we have the White, Orange, Green, and Brown-colored dwarves. After those, there are the dwarves, though, they're metallic now. Finally, we have the lowest-tier, which are represented by common mining tools such as a lantern, helmet, etc.
P.S The biggest coin jackpot offered here equals 112,500 coins.
Best Boom Brothers Slot bonus feature
The Wild is the Bomb symbol and it can swap for any other symbol in the game except for the Scatter. It can appear on any reel, so if you manage to hit five Wilds, you'll be rewarded a huge jackpot of 7,500 coins. Otherwise, hitting just one helps you form better winning combos.
As for the Scatter, it's represented by the Free Spins bonus symbol. With this one, you can only trigger the free spins mode if you can hit at least three Scatters. Your rewards, therein, ranges from 8 free spins up to 50. Likewise, at least a 3x multiplier will be applied to all your free spins. Lastly for this part, netting a single Scatter symbol gives you a free spin (can be stacked).
The final bonus feature is tied to the rail track symbol. If you hit three of those, your winnings will be doubled. Hit five instead, and your winnings will be quadrupled. There's one more stage, where you can get up to a 1,900x multiplier. It all depends on whether or not you choose the brother with a diamond (highest-valued), ruby, or gold.
