Review and recommendations by the testing team
Despite its outdated graphics; the exciting gameplay and a large number of additional features, make you want to play. But regarding payouts, it is disappointing.
- In the main game, winning combinations are rare, and their payout is extremely low, which does not help with keeping the balance. It is almost impossible to get a big win in the main game, despite the additional feature “second chance”.The “second chance” features often appears; once in every 3 - 5 spins but brings no result, and in most cases is a combination with a minimum winning.
- The bonus feature is triggered often enough, and it is possible to get the highest paying value (diamond). But again, the payout is disappointing, since in most times the winning is the lowest possible.
- This slot rarely gives out free spins feature. The winning combinations do not differ from the resulting combinations in the main game, and the difference is only in multiplayer x3. The average value of the feature is only 20x - 40x total bets.
- Neutral recommendations about fulfiling the bonus requirements (in the middle range). When playing with real money, it is recommended to make no more than 50-80 spins to get a bonus feature and no matter of its result, leave the slot.

The bonus features of Boom Brothers slot
Boom Brothers slot offers to players progressive (two stages) bonus feature, and the free spins feature with x3 multiplier. Let's describe each of the steps of the "Rail Track" bonus features.
The bonus feature Rail-Track
If you managed to catch three symbols with the inscription "Rail track" series (left to right) in the active pay-line, the bonus feature would start.
- Symbols with rail can appear only on 1, 2 and 3 reels. To trigger the bonus feature, it is necessary that these symbols appear in positions from left to the right, on the active pay-line.
- After triggering the Rait-rack bonus feature, the first three reels will try to form a rail track, while the last two reels spin again. To start the final round of the bonus feature, the remaining two reels (during re-spin) should have rails to create a path to the final bonus round. In this case, the slot will pay 4x, and the player moves to the final bonus round.
- If a rail symbol was caught only on the 4th reel, then the slot pays 3x, and the feature ends.
- If none of the reels was a rail symbol, our bet will be doubled, and the feature ends.
The final round of the Railtrack bonus feature
The final round of Railtrack bonus feature has a maximum potential of winning. Here the player can hit the maximum winning of 112 500 coins.
- At the bottom of the screen, you will see three carts.
- Selecting one of the carts, you will receive jewels. Each of the stones corresponds to one of the gnomes.
- As soon as one of the gnomes gets to the prize, it will be credited to your balance.
The free spins feature
Symbols with the inscription "Free Spin" (three or more) trigger the free spins feature. You will get 15 free spins with the x3 multiplier. Free spins can be re-triggered.
