Mine Blown

Mine Blown: slot overview

Mine Blown is an underground mining slot from NetEnt, playing out on a 5-reel, 3-row grid with 10 active paylines during the base game and free spins, and switching to a collect-based win system during its separate bonus spins mode.

Theme and gameplay feel

The setting is a subterranean wooden mine shaft, complete with a jiggling pipe, blowing fans, and a suitably claustrophobic but atmospheric backdrop. There's no miner character on screen, which is a slight departure from genre convention, but a guitar-driven rock soundtrack fills the gap nicely, giving the reels an energetic edge. The bonus spins mode takes place at a deeper, sturdier-looking level of the mine, visually separating it from the base game and free spins.

How it plays

Winning combinations start from the leftmost reel and pay left to right, with Ten through Ace forming the lower-value symbols and mining equipment — picks, lanterns, shovels, and helmets — making up the premium end of the paytable. A wild symbol substitutes for all other paying symbols to help complete combinations.

Bonus features

Two trigger symbols landing on the leftmost and middle reels, together with other special symbols, set off either the free spins round or the bonus spins round. If two triggers land without a bonus symbol appearing, players still walk away with 3x the stake as a consolation win. During free spins, wilds become sticky, while bonus spins revolve around collecting values from Vein symbols. A Dynamite Feature and a separate TNT Feature add further random win potential, with dynamite symbols capable of exploding to trigger extra rewards.

RTP and what it means for you

Mine Blown returns 96% to players at its highest configuration, a solid figure that sits comfortably above the wider market average.

Volatility and betting range

Rated medium volatility, Mine Blown offers a reasonably balanced pace — frequent enough action to stay engaging, with the sticky wilds and Vein-collecting bonus spins providing genuine spikes when they trigger. Stakes run from 0.10 up to 40 per spin, with no ante bet or feature buy option available.

Verdict

Mine Blown blends a solid, above-average RTP with a genuinely varied feature set — sticky wild free spins, collect-based bonus spins, and random dynamite triggers all give it more depth than its fairly compact 10-payline structure might suggest. It's a well-rounded pick for players who enjoy mining themes with a rock-and-roll edge, and the guaranteed 3x consolation win for landing two triggers without a bonus symbol is a nice touch of extra fairness that not every developer bothers to include.
