Compatibility: Mobile, Tablet, Desktop

With a mining theme, the Gold Mine Stacks slot takes you on a quest for gems and gold. Produced by Nailed It! Games in co-operation with Microgaming, it’s quite simply designed. It’s a world away from Nolimit City’s Misery Mining visually.

Set at the foot on a mineshaft, it has an American feel to it with a guitar/banjo style soundtrack. It’s quite intense and could easily feature in a Western movie. The graphics are high-definition though with the symbols standing out from the dark stone backdrop.

On the reels, you will see A, K, Q and J royals as well as blue, green, purple and red gems. The red gem symbol is the best paying awarding 1, 10 or 20 x your total bet for 3, 4 or 5 in combination.

You will also find a Gold Nuggets Wild symbol which can appear on all 5 reels. Substituting for all paying symbols described above, 3, 4 or 5 wilds in combination awards 1, 10 or 20 x bet. Finally, there is a Gold Coin Bonus Scatter which is key to triggering the main bonus feature.

Released on the 24th of November 2022, the Gold Mine Stacks slot has been producing using HTML5 technology. This allows for play on mobile, tablet, laptop and PC devices. The 5×3 setup works well on mobile devices including those that operate with iOS, Android and Windows.

Wild Stacks Respins feature

gold-mine-stacks-slot-wild-stacks-respins-feature

The Wild Stacks Respins feature is triggered when a Gold Nuggets Wild symbol stack appears on a reel. With the Gold Nuggets Wild Stack remaining fixed in position (i.e. sticky), respins are awarded until no full wild symbol stacks land on the reels. If you manage to fill all 5 reels with Gold Nuggets Wild Stacks, you’ll pocket 400 x your total bet.

Gold Mine Stacks Bonus feature

gold-mine-stacks-gold-mine-stacks-bonus-feature

Landing 3 or more Gold Coin Bonus Scatter symbols anywhere on the reels will activate the Gold Mine Stacks Bonus feature. Before you begin, the Randomizer randomly boosts 1 of the Bonus Prizes up to 50x. Bonus Prizes are worth between 1 and 50 x your total bet.

Starting at level 1, each level offers 8 Bonus Prizes that can land on the reels. The win potential increases with each level you reach. To reach the next level, you need to land 3 Bonus Prizes on a reel. Here’s a table highlighting the Bonus Prizes available in each level:

Level Bonus Prizes
1 1, 2, 3, 5, 7, 10, 25 and 50 x bet
2 2, 4, 6, 10, 14, 20, 50 and 100 x bet
3 3, 6, 9, 15, 21, 30, 75 and 150 x bet
4 5, 10, 15, 25, 35, 50, 125 and 250 x bet

Once you begin playing, you will get 3 lives/spins. Each Bonus Prize resets the spins tally to 3. The feature ends when no Bonus Prizes land for 3 consecutive spins or when the reels are filled with Bonus Prizes on level 4.

Furthermore, land 3 Bonus Prizes on a reel on level 4 to apply Total Win Multipliers. Fill 1, 2, 3, 4 or 5 reels will see a 2x, 3x, 5x, 7x or 10x multiplier applied respectively.

To increase your chances of triggering Gold Mine Stacks Bonus feature, there is a Bonus Bet feature. Your bet will increase by 25% but your double your chances basically. This means the bonus frequency rate goes from 1 in 400 spins to 1 in 200 spins.

Finally, players outside the UK have the option is the Buy Bonus feature. Buy your way into the Gold Mine Stacks Bonus feature for 100 x your total bet.

Originality








The Gold Mine Stacks slot follows the same formula as countless other mining themed slots in terms of gameplay. Visually, it’s not as impressive at Misery Mining or Diamond Mine Megaways (Blueprint Gaming) but the soundtrack is superb.

When it comes to the bonus features, landing Wild Stacks will lead to respins and the possibility to fill all 5 reels with wilds. That said, a 400 x bet payout is awarded if you do so. The main attraction is the Gold Mine Stacks Bonus feature where you aim to land as many Bonus Prizes as possible. The Randomizer before the feature begins can give you a real leg-up too.

Filling reels with Bonus Prizes will advance you through the levels with bigger Bonus Prizes up for grabs the further you venture. If you make it to level 4 and fill 1 or more reels, a multiplier up to 10x will apply to your Bonus Prizes total. With 50,000 x bet max wins available, the Gold Mine Stacks slot is 1 of the better paying games with this theme.

In summary, Gold Mine Stacks is a relatively simple slot in terms of gameplay and design. However, it does offer top payouts of up to 50,000 x bet from the main bonus feature.

If you want more bonus features, you cannot go wrong with Bonanza Megaways by Big Time Gaming. 1 of the most popular slots online, it’s the most played Megaways slot ever and comes with 26,000 x bet max wins.

If you fancy mining for gems and gold, Nolimit City’s Fire in the Hole slot would be my pick. Superbly designed, wins lead to more rows and up to 46,656 ways to win. With xBomb Wild multipliers, there’s a Lucky Wagon Spins feature where coins award prizes. There are lots of special enhancers which enhance your winning potential up to 60,000 x bet.

Pros
  • 50,000 x bet max wins
  • Wild Stacks + respins
  • Big Bonus Prizes in main feature
Cons
  • Gameplay not original
  • Bonus features commonly found
