Mine Blown slot: collecting gems and locking Wilds

Dynamite falls in; TNT lands on a reel

The reels are only part of the action. A random Dynamite effect can throw explosives towards the grid; those that reach it turn affected symbols into Wilds. You do not aim the sticks or choose the blast positions.

TNT works from a visible symbol instead. In mine-blown, one TNT symbol can land anywhere on the reels. Its explosion changes that position and some neighbouring positions into Wilds.

The golden W substitutes for ordinary paying symbols, including the mining tools and card ranks. It cannot replace the Trigger, Free Spins or Bonus symbols needed to open a feature. An explosion can improve the layout, but the resulting symbols still have to make a paying combination.

In Bonus Spins, both explosives reveal collectible Veins instead of creating Wilds, as NetEnt's feature description explains.

Bonus Spins: fill the cart without matching lines

The cart feature in mine bown needs Trigger symbols on reels one and three, plus the Bonus symbol on reel five. It starts with three Bonus Spins and a cart worth 3× your stake beneath the middle reel.

From here, matching lines are no longer the job. Vein symbols contribute wherever they appear. Their values go into the cart, and the accumulated amount pays when the feature finishes.

An Undiscovered Vein has no collection value of its own. Dynamite or TNT can break it open to reveal a paying Vein. The coloured gems also add time to the feature, so a useful find can change both the total and the number of spins left.

These are the values in Evolution's current demo, corroborated by the gem section of the detailed game rules.

A cart total is a sum

Suppose your cart starts at 3× and collects Gold followed by Sapphire. It now holds 9×, and Sapphire has added one Bonus Spin. A later Diamond would take that total to 59× and add another three spins.

At a €0.20 stake, that 59× total would pay €11.80.

That makes the extra-spin column as important as the value column. A Diamond raises the total sharply, but its three additional spins also leave room for more finds. Gold increases the total without extending the feature.

Free Spins build a board of locked Wilds

Trigger symbols on reels one and three, together with a Free Spins symbol on reel five, award an immediate 3× stake payment and ten Free Spins.

Here the regular line game continues. Wilds that appear stay in their positions for the rest of the feature while the remaining symbols spin again. Another Free Spins symbol adds three spins, giving the locked Wilds more rounds in which to take part.

Dynamite and TNT still create Wilds during Free Spins.

Two Triggers can also pay 3× when no Bonus symbol appears on reel five, even if neither feature starts. That small trigger award should not be confused with entering the cart round, whose opening value is also 3×.

Ten paylines handle the ordinary symbols

Outside the collection feature, mineblown uses a five-reel, three-row grid. A line win needs at least three matching symbols running from the leftmost reel. Different winning lines add together; each individual line pays its highest eligible combination once.

The hardhat leads the ordinary paytable at 500× for five. Evolution's demo lists the full set as multiples of the total stake:

Five Wilds have a separate 500× line payout. Shorter groups of Wilds can help complete an ordinary-symbol combination rather than paying a separate three- or four-Wild prize.

You can change the stake using the bet controls; the paytable's cash amounts change with it. A 500× entry at €0.20 corresponds to €100 for that combination. It is a line value, not the maximum for an entire round.

What the 25× and 50× feature buttons buy

Where feature buying is enabled, mine-blown offers two purchases:

• 25× the stake: entry to Free Spins.
• 50× the stake: entry to the cart's Bonus Spins.

At a €0.20 base stake, those prices are €5 and €10. A 30× cart would return €6, leaving a €4 loss against a €10 purchase.

Decide which mechanic you want to try and compare the full price with your spending limit.

Evolution notes that bonus-buy availability depends on jurisdiction.

RTP, hit frequency and the 20,000× ceiling

The NetEnt catalogue and Evolution listing give these figures for mine bown:

The two percentages answer different questions. RTP describes the game's theoretical long-run return across wagers. Hit frequency counts winning outcomes, which can include amounts smaller than the stake. It is not the frequency of profitable spins, bonus entries or Diamonds.

Evolution's demo lists 96.12% for its feature-buy setting; casino configurations and stake limits can differ.

The 20,000× figure is a maximum, not a typical bonus result. High volatility leaves room for uneven sessions and stretches without a substantial return.

The official demo has no progressive jackpot configured. If a casino attaches a separate jackpot system, use that operator's rules for its mine-blown version.

Open the game on desktop or phone

On a phone, fullscreen gives the fifth-reel feature symbols and cart more room. NetEnt lists HTML5 support for desktop and mobile browsers, so this route needs no dedicated mine bown app or APK.
