Boom Brothers Bonus Features

The Rail Track special feature is triggered when 3 Rail Track symbols are seen on active paylines on the first 3 reels. The last 2 reels will spin again, and once the train tracks have been formed, a bonus game will begin.

When the track is made up of all the pieces, winnings come with a 4x multiplier. If a piece is missing, winnings have a 3x multiplier. Should two pieces of track be missing, you will not be taken to the bonus game, however, your winnings are doubled.

The bonus game shows 3 carts at the bottom of the screen. Pick a cart, and see which treasures are revealed. There is a dwarf allocated to each of the carts. Whichever dwarf is connected to your chosen mining cart will blow up the rock wall, and you will see your bonus win.

The free spins feature is triggered when 3 or more free spin symbols are seen on the reels. In order to see how many free-spins you have won, keep an eye on the free-spin symbols as each one turns around and reveals between 8 and 50 free spins. The number of free spins is the combined total of all the numbers that have been revealed.

All winnings in the free spins round come with a 3x multiplier except when plying the bonus game. Each free spin symbol seen during the free spins round, will award you with an additional free spin.
