Game Overview
I often wonder if game providers have a wheel of fortune in their brainstorming room, and when all else fails when coming up with an idea, they give it a spin to reveal what the theme of their next slot will be. I imagine it includes categories like Egyptian, Fishing, Candy, Greek, and Western, but in Stakelogic’s most recent spin, it must have landed in the Mining section. So, what exactly do we have for you today? I can reveal we’re about to review the Gemstone Mine slot, an 8-reel game operating on the cluster pays engine with an RTP of 96.11% and a maximum win of 7,500x bet.
As the 8-reels likely suggest, Gemstone Mine is a mammoth grid slot. Unsurprisingly, with such a huge playfield, the cascading reels engine has been baked into the gameplay. This activates when a winning combo is formed, replacing winning symbols with new ones for extra chances to win. Furthermore, all winning combos have a chance of eliminating blockers from the sides of the reels that will uncover multipliers with a potential value of 500x. If the free spins feature is triggered, all collected multipliers will not reset between losing spins, giving you a better opportunity to land a substantial win.
Prospecting is no easy task, so if you want to gain a headstart on your competitors and find yourself a fortune, I’d suggest spinning the reels on our Gemstone Mine demo slot. It’s free to play below.
Gemstone Mine Slot Theme, Stakes, Pays & Symbols
You might have gathered from my sarcasm in the intro that there are a fair few fun free slots available to play if you want to dig deeper (excuse the pun) into the mining niche of games. As always, we’re not one to leave you hanging about which are the best titles in the niche to play, so we’d suggest firing up our Gems Bonanza free play slot from Pragmatic Play, along with the fantastic Bonanza slot demo, a Megaways release from Big Time Gaming that comes with up to 117,649 ways to win.
Okay, recommendations aside, let’s get back to the Gemstone Mine slot review. Our next place of interest is the pays section, where at the top of the paytable, we have the Large Blue Gem worth 150x for winning clusters of 15 or more. Next is the Large Purple Gem worth 80x, with the final premium symbol being the Large Red Gem valued at 60x. The lower value symbols are represented by smaller gems, with the Green, Blue, Purple and Orange Gems paying 30x, 25x, 20x, and 15x, respectively.
Stakelogic has included a wide range of bet sizes in Gemstone Mine, ensuring players of all budgets can enjoy the game for real money. The standard prices to play begin at a minimum of €0.20 and max out at €20 a press.
Gemstone Mine Slot Base Game & Modifiers
Initially, on Gemstone Mine, the gameplay begins on a 6×6 grid, but whenever a winning combo is formed by 5 or more matching symbols connecting adjacently within the playfield, any symbols touching an outside block will cause it to part explode. If a blocker symbol has two wins explode next to it, it will open up and reveal a multiplier ranging from 2x to 500x, which will be saved and applied to all future wins in that series of spins.
Additionally, all wins will activate a reel tumble, which removes winning symbols from the reels, allowing new ones to fall for above for more chances to win.
Super Stake
Activating the Super Stake option will double your bet size but increase your chances of hitting more valuable winning connections.
Gemstone Mine Slot Bonus Features
Whenever 4, 5, or 6 of the dynamite scatter symbols land in play during the base game, the bonus round will be triggered and 10, 15, or 30 free spins will be triggered.
Free Spins
When the free spins are active, all blocker symbols removed will stay that way for the duration of the bonus. Furthermore, all multipliers that are unlocked will be stored in a global multiplier and applied to every win that is achieved. Players can also win five extra spins if 3 scatters land during the feature.
Super Free Spins
If the super free spins bonus is triggered, all blocker symbols will only require one explosion for their multiplier to be revealed.
Bonus Buy
Gemstone Mine is a feature buy slot, and the standard and super free spins can be bought for 100x and 250x, respectively.
Pros
- High multipliers can be built up during the free spins.
- Multipliers are present in the base game and bonus.
Cons
- The gameplay doesn't feel as smooth as some other games in the grid slot niche.
Gemstone Mine Slot Review Final Thoughts
It's hard not to compare Gemstone Mine with slots like Sugar Rush 1000, where big multipliers are present in all aspects of the game.Personally, I felt as though Stakelogic's effort falls short of releases such as Sugar Rush, and whilst it may offer some entertainment initially, I suspect you'll soon get bored of it and move on to something else.
