Mine Blown™ Slot Review – Free Play by NetEnt

Mine Blown™ Slot Facts

The Mine Blown slot from NetEnt detonates its way to a maximum payout of 20,000 times the stake on a 5x3, 10-payline grid built around exploding Dynamite and TNT icons. Those blasts turn nearby icons into Wilds during ordinary spins, or into prized Gold and Gem icons after the Bonus Spins round takes over.

Extreme volatility and a 22.73% hit frequency make this one of NetEnt’s toughest, highest-ceiling releases, with a mine cart building up a growing total from Gold and Gem pieces across the Bonus Spins. The free demo on this page is worth trying before spinning with real money.

Mine Blown Theme & Design

Mine Blown drops players into a mine shaft setting built entirely around the tension of the next detonation, with Dynamite and TNT icons standing in for the usual wilds and scatters. Gold and Gem icons carry the visual payoff of the theme, only turning active after the Bonus Spins round has begun, when a mine cart starts hauling in whatever the explosions uncover. The whole design leans on that mining-and-blasting loop, where every explosion is both a visual moment and a mechanical trigger, tying the underground setting directly to how symbols change across the reels.

How Mine Blown Plays

Spins run across a 5x3 grid with 10 paylines, where Dynamite and TNT icons can appear at random and set off a blast that turns themselves and whatever sits next to them into Wilds. Two Trigger icons landing on the grid by themselves, with no bonus marker present, still return a flat payout of 3 times the stake. Bring a Free Spins icon into play on the rightmost reel while Triggers occupy the leftmost and center reels, and 10 Free Spins begin instead, with any Wild that lands staying frozen in place for the rest of the round and a repeat Free Spins icon tacking on 3 more turns. Swap that rightmost-reel icon for a Bonus marker under the same Trigger setup and 3 Bonus Spins open instead, where detonations start building up a mine-cart total out of Gold and Gem pieces, each type adding its own amount toward the payout once the round finishes.

RTP, Volatility & Win Potential

Mine Blown returns 96.15%, just above the industry average of around 96%, but the Extreme volatility label is the figure that matters most for how a session actually feels. A 22.73% hit frequency means paying spins are genuinely scarce, landing on roughly one spin in four to five, so long dry runs between detonations are part of the design rather than bad luck. That scarcity is the trade-off for a 20,000x maximum payout, built from the Bonus Spins mine cart stacking Gold, Sapphire, Emerald, Ruby, and Diamond pieces into one accumulated total before the round ends.

Our Verdict on Mine Blown

This Mine Blown slot review is aimed squarely at players who want the biggest possible swings and don’t mind waiting for them, since a 22.73% hit frequency and Extreme volatility make patience part of the deal. The genuine strength is the Bonus Spins mine cart, which can snowball into serious value once Ruby and Diamond pieces start appearing. The honest weakness is how rarely that happens outside the bonus, so anyone chasing frequent small wins should look elsewhere. Try the free demo on this page first to see the pacing for yourself.

Mine Blown™ Bonus Features & How They Work

Dynamite

Dynamite icons can drop anywhere across the grid at random, and once they go off, the blast turns the symbols sitting closest to them into Wilds for that spin. Step into the Bonus Spins round and the same explosion behaves differently, converting those neighboring positions into Gold or Gem pieces instead of Wilds, which is how the mine cart’s total actually grows.

TNT

A lone TNT icon can appear anywhere across the grid, and its blast changes both itself and whatever sits beside it into Wilds under normal play. During the Bonus Spins round, that same blast instead produces Gold or Gem pieces on those neighboring spots, directly feeding the mine cart’s running total.

Triggers

Trigger icons are what open the door to both bonus rounds, and even just two of them appearing together, with no bonus marker in play, still hands out a flat payout worth 3 times the stake. Pairing Triggers with the right icon on the rightmost reel is what actually unlocks either Free Spins or Bonus Spins instead of that flat prize.

Free Spins

This bonus opens once Triggers occupy the leftmost and center reels alongside a Free Spins icon on the rightmost one, starting players off with 10 free turns. A second Free Spins icon appearing anywhere during the round tacks on 3 additional turns, and any Wild that lands freezes in place for as long as the round continues, letting them build up rather than reset each spin.

Bonus Spins

The same Trigger setup instead opens 3 Bonus Spins when a Bonus icon lands on the rightmost reel, starting a mine cart at 3 times the stake. Gold and Gem pieces collected during these spins add to that cart: Undiscovered adds nothing but can reveal another type when exploded, Gold adds 1, Sapphire adds 5, Emerald adds 10 plus an extra spin, Ruby adds 25 plus an extra spin, and Diamond adds 50 plus three extra spins, with the full total paid out at the end.

Buy Feature

Instead of waiting for the right icons to line up naturally, this option pays for guaranteed entry into either round. A cost of 25 times the stake locks in the Free Spins trigger outright, while 50 times the stake locks in the Bonus Spins trigger instead, both bypassing the need for Triggers and the rightmost-reel icon to appear on their own.
