Boom Brothers slot machine is made out of 5 reels and up to 20 bet lines. Each line has 5 levels for betting to allow a wide range for all players. The game features Wild symbols, Free Spins, a Railtrack Feature, a Bonus Game plus the innovative random function "2nd Chance" that allows the repetition of a non-winning hand. The Wild symbol substitutes for all symbols except for the Free Spins and Bonus symbols. When three or more Free Spins symbols appear on the reels, they will trigger the free spins. Each of the symbols will reveal a number ranging from 8 to 50. The sum of the numbers given represents the amount of free spins obtained. During this mode, the winnings are tripled and each extra Free Spins symbol (during the free play can appear only on reels 3, 4 or 5) is entitled to an extra free move. In addition, the Free Spins symbol also acts as a Scatter. All of the wins obtained from the free spins are multiplied by three. When 3 symbols appear on reel 1, 2 or 3 they will start the Railtrack mode. Five of these symbols will start the bonus game. This will take players to a different screen where there are three tracks, each of them with one machine operated by a dwarf. On the bottom, three carts will appear and the player must click on one of them to reveal the mineral inside. Based on the obtained mineral, the machine on the respective track will advance and the one that reaches the end will award the prizes. Each of the three rails lead to a different mineral and thus have different payout ranges. The 2nd Chance function can be triggered randomly on a no-win game to offer another shot for free. The regular symbols show four creations of the innovative dwarfs and different tools used in mining the precious stones and materials.
