Boom Brothers is a 5-reel, max 20-payline '3D' online slot from NetEnt. This explosive game really took the slotting world by storm when released just before Christmas 2010, and helped NetEnt establish itself as arguably the software company that can most fairly claim to be 'top of the slots'. With its '3D' style graphics and cinema-standard animation intro, NetEnt really upped to ante when it came to online slots, leaving most of their rivals trailing in their wake.

This game is all about an explosive mine. There are three dwarves involved (we assume the surviving three have blown up the other four) who operate a gemstone mine and whom seem on an eternal search for the ultimate prize – a gleaming, super-sized diamond. The symbols used in this game are metallic masks that we guess have been welded together by our hapless trio, a model of a tiny chap, a railtrack sign, a Davey lamp, a pair of pick axes, half a bucket and a uniquely-designed miner's helmet.

This slot has a maximum of twenty pay lines and you can have as many in play as you want with each spin. You can also choose your bet level (effectively the number of coins you want to risk with each spin), and your coin size from 0.01 to 1.00. When you've sorted out all these options, your final bet-per-spin is your coin size multiplied by your bet level multiplied by the number of lines that you have in play. When you're ready to go underground, hit the spin button.

Payout & bonus rounds

The lowest payout in this slot is for three identical pieces of mining equipment (the full list is given above) or two wilds. You will win five coins if you succeed in this manner. The highest win in normal play is awarded for five 'Wild Bomb' symbols, which will win you seven and a half thousand coins.

The WIld Bomb symbol substitutes for all other symbols in this game except the free spin and bonus symbols.

The free spins symbol in this game is simply the words 'Free' and 'Spins' written on a screen. If you land three or more free spins symbols during play you win a number of free spins in which all wins (aside from feature wins) are tripled.

Upon any losing spin one of the dwarves may appear and drop bombs at the bottom of some reels. When this happens, the reels will explode and new symbols will fall into place, potentially triggering a winning line up.

If you land three pieces of railroad track on the first three reels then the track will line up and a dwarf will appear. The fourth reel will spin, and hopefully another piece of track will fall into place, and then a fifth. You are awarded a pay out if there are at least three items of track on the reels. If the dwarf makes it across all five pieces of track then you are awarded the bonus game.

All three dwarves appear at the edge of three tracks for the bonus game. It's your job to guide one of the dwarves across the track for a cash payout. You get to select diamonds, rubies and gold bars from rail carts. Each piece is worth up to three places along the track for the respective dwarf, and the dwarf who makes it across first is the winner. He will lay a bomb that will explode coins into your slots account.

Boom Brothers really shook up the slotting world when it appeared, and it's no wonder it did with its colourful graphics and exciting game play. Although better slots have come along since, this remains a hot favourite with thousands of online slots players, and once you've enjoyed a few spins, it's easy to see why. One of NetEnt's true slotting classics.
