Gold Mine Stacks Review
When Jesus returned to his heavenly Father, the first thing he allegedly said was “nailed it!”. At least according to a joke we read on the internet. The developer has created a cartoon-style mining slot as their first release, and Gold Mine Stacks comes with some interesting innovations.
The 5x3 grid blocks the entrance to the mine, and you get sticky stacked wild respins that can fill the grid with wilds in the base game. The bonus round takes you deep into the mine shaft, and it’s a streak respins style feature that comes with 4 levels. Each level awards higher prize ranges, and the 4th level can also give you a total win multiplier for up to 50,000x payouts.
Gold Mine Stacks Slot Features
The premium symbols consist of 4 different color gemstones, and these pay between 8 and 20 x your stake for 5 of a kind wins. The mining cart full of gold is the Wild symbol, and it steps in for pay symbols to help complete wins. The wild also pays the same as the top-tier red gemstone if you land pure wild wins.
Landing full wild stacks that fill the entire reel triggers the Full Wild Stack Respins feature. The triggering stack or stacks become sticky as the remaining reels respin, and this repeats as long as you land new full wild stacks. Filling the screen with wild stacks means you win 400x your stake, which is the single spin max win in the base game.
You need at least 3 bonus symbols (gold coins with a value of 5x to 50x) on a base game spin to trigger the Gold Mine Stacks Bonus Round. You start with 3 lives in the spin tally, and the tally resets as long as you land at least one bonus symbol. Landing only blanks removes one life, and the feature is over when all 3 lives are lost.
As the Bonus Round starts, the Randomizer will boost one bonus cash symbol by up to an x50 multiplier, and the feature comes with 4 levels. Each level comes with a more valuable range of bonus prizes. Level 1 gives you prizes between 1x and 50x, level 2 awards between 2x and 100x prizes, level 3 comes with prizes between 3x and 150x and level 4 awards bonus prize symbols between 5x and 250x your stake.
You level up by filling a reel with bonus symbols, and the grid is cleared each time you level up. Once level 4 is reached, filling a reel with bonus symbols awards a total win multiplier. You get a multiplier of x2, x3, x5, x7 or x10 when you fill reels 1, 2, 3, 4 or 5, respectively. The multiplier will boost the total win from the bonus round.
You can choose to play with the Bonus Bet feature on or off in the base game, and it costs 25 % more per spin to keep it on. The benefit is that your bonus round chances are doubled. In addition, non-UK players, and anyone eligible, may purchase the bonus round for 100x the stake. The organic hit rate is 1 in 400 spins on average without the Bonus Bet.
The 200 Spins Gold Mine Stacks Slot Experience
You get to see a brief full wild stack respin as the 2-minute highlights video starts, and then we purchase the bonus round around 0:25 into the video. We got the 7x bonus symbol boosted by x2 for the duration of the feature from the Randomizer, and you can see for yourself which level we achieved by hitting the play button below.
Review Summary
The name is admittedly a cool sounding name for a game developer, but it opens you up to plenty of puns in cases where you didn’t. Gold Mine Stacks is a pretty decent debut however, and we know that a follow-up is already planned for 2023. Visually, there isn’t anything revolutionary going on, but the cartoonish style has its charm.
The full stack wild respins feature keeps the base game somewhat interesting, but the prize for a full screen of wilds could perhaps have benefitted from some kind of multiplier to make it even more juicy. Having one bonus symbol multiplied is somewhat innovative, and the same can be said about the level-up and win multiplier system. This allows for larger than usual prizes, and the 50,000x win cap does come across as achievable.
