Boom Brothers Slot Review

Boom Brothers is a quirky, steampunk-inspired mining adventure from NetEnt. 

Across 5 reels and 20 paylines, three bearded brothers blast through an underground gold mine with TNT, serving up wilds, free spins with 3x wins, and a cinematic Railtrack Bonus. 

Expect polished 3D visuals, a playful intro cutscene, and the kind of animation quality you’d associate with NetEnt hits like Gonzo's Quest and Jack and the Beanstalk.

Boom Brothers Theme & Presentation

• Setting: A rattling mine-shaft with chain-linked reels and explosive set pieces.
• Symbols: Metallic brother masks (high pays), plus lanterns, hard hats and pickaxes (low pays).
• Style: High-end 3D art, slapstick mining mishaps, and “boom-tastic” transitions that keep spins lively.

Boom Brothers Reels, Lines & Betting

• Layout: 5 reels • 20 fixed paylines
• Wins: Left-to-right on active lines; paytable accessible in-game
• Compatibility: Smooth on desktop and mobile (iOS/Android) with crisp animations

Boom Brothers Features, Specials & Symbols

• Wild Symbol: A cartoon fuse bomb that substitutes for regular symbols to complete wins.
• Free Spins: Trigger the round with the Free Spins logo; all wins are tripled (3x) during the feature.
• Railtrack Symbols: Three, four, or five Railtrack icons in view apply rising multipliers (2x, 3x, 4x) to your bet evaluation and five Railtracks also launch the bonus game.

Railtrack Bonus Game

Each brother rides a steampunk mine cart on his own track. Pick cards to move them forward; the first to the goal awards its prize. Track rewards are tiered—with gold at the bottom, rubies in the middle, and diamonds at the top—culminating in a diamond prize for the best returns. It’s an engaging, animated interlude that fits the theme perfectly and can deliver standout payouts.

How Boom Brothers Plays

Boom Brothers shines when the “boom” factor kicks in: random explosive animations, wild substitutions, and free spins with a 3x boost keep the pace snappy. The Railtrack Bonus adds variety and a second route to bigger wins, while the main game’s premium masks can still do serious work on stacked line hits.

Our Boom Brothers Verdict

With charming characters, top-tier presentation, and a pair of punchy bonuses, Boom Brothers remains a feel-good NetEnt classic. If you enjoy animated adventures with frequent visual payoffs and a memorable bonus game, saddle up the mine cart—it’s well worth the ride. Prefer more myth and magic? You can also spin the cult favourite Rainbow Riches for a different style of feature-led fun.
