Boom Brothers is a NetEnt slot released in November 2013. Set in an underground mine, it follows three dwarf brothers - a softy, a cranky one, and a funny one - as they dig for treasure. The 3D graphics and character animations were impressive for the time and still hold up well. It sits at 5 reels, 3 rows, and 20 fixed paylines.
RTP and Volatility
The RTP is 96.4%, which sits comfortably above the industry average of around 96%. Low volatility means wins come frequently but tend to be smaller. Your balance moves in a fairly steady pattern rather than swinging between long dry spells and big hits. This makes Boom Brothers well suited to players who prefer longer sessions without burning through their budget quickly.
Betting Range
Stakes run from £0.20 to £50 per spin. The minimum is set by the 20 fixed paylines at £0.01 per line. With a max win of 1,125x your stake, the ceiling on a £50 spin works out at £56,250.
Key Features
Second Chance Feature
The three dwarf brothers can randomly appear on any non-winning spin. Each brother has his own style - one throws a stick of dynamite at the reels to swap symbols, another triggers a TNT explosion that forces a respin, and the third can shift symbol positions to create a win. This feature fires randomly rather than being tied to specific symbols, so it keeps things lively during base game play.
Rail Track Bonus
Land three or more Rail Track bonus symbols and the brothers climb into separate mine carts, each rolling down a different track toward treasure chests. The track you end up on determines your prize. Five Rail Track symbols also apply rising multipliers - 2x, 3x, or 4x - to your win total before paying out. This is the game's most involved bonus and the one that can deliver the bigger wins.
Free Spins
Three or more scatter symbols award free spins. The number of spins is revealed when the scatters land - anywhere from 8 to 50 spins are possible, with all wins during the free spins round multiplied by 3x. Landing another set of scatters during free spins retriggers the feature.
Wild Symbol
The white dwarf face acts as the wild. It substitutes for all symbols except the scatter and bonus, and pays up to 375x your line bet for five on a payline. It does not expand but appears across all five reels.
Bomb Jackpot
Collect five bomb symbols during play and you trigger a 7,500-coin jackpot prize. At maximum bet that equates to the upper end of the max win range.
Theme and Graphics
The mining theme is handled with genuine character. The three brothers are distinct personalities, each animated with NetEnt's 3D engine. An intro cutscene plays on load and the brothers appear throughout base play via the Second Chance feature, which keeps the theme active rather than limiting it to bonus rounds. Lower-value symbols use mining equipment - pickaxes, helmets, lanterns, buckets - while the three coloured dwarves (brown, green, and orange) fill the mid-to-high value slots. The soundtrack is suitably underground with rhythmic pickaxe effects and a rolling ambient score.
Mobile
Boom Brothers runs in HTML5 and works in any modern mobile browser. No app is needed. The layout adapts to smaller screens without losing the core animations. The Rail Track bonus and free spins both function the same way on mobile as on desktop.
Is Boom Brothers Worth Playing?
Boom Brothers rewards patient players. The low volatility and 96.4% RTP make it one of the steadier games in NetEnt's catalogue for grinding through longer sessions. The Second Chance feature keeps the base game engaging - there is always a chance one of the brothers will intervene on a losing spin. The Rail Track bonus is the standout feature, delivering the largest potential wins. If you prefer high-volatility slots with rare but massive payouts, this probably is not the right match. But for a charming, well-made game with consistent action, Boom Brothers has earned its reputation as one of NetEnt's more durable releases.
