This classic slot doesn’t include any bonus features or even a Wild, it’s just traditional, simple gameplay on an interesting and unique styled reel grid.

Introduction

Gem Miner is an interesting and unique online slot from the young gaming company, Expanse Studios, who were founded in 2019. The game doesn’t feature any exciting bonus features or special effects but instead focuses on providing quality, classic slot gaming on a reel grid that’s sure to entice. 

Set deep underground, the goal of Gem Miner is (you guessed it) to dig for precious gems and diamonds. To take home the gold in this slot, all you need to do is line up 3 matching symbols along one of the 3 paylines. There are handy wooden arrows pointing to each line that will quickly let you know where a win has occurred and how much your valuable minerals are worth. 
The game is free from distractions such as Wilds or Scatters, but does make up for this with an interesting reveal of gems and some huge top prizes up to 1,000x your stake! 

Theme, Graphics & Soundtrack 

As you might have guessed from the title of this slot, Gem Miner is set deep underground in a mineral mine, complete with a yellow canary overlooking the operation to the right of the reels. The reels themselves are built from an enchanting wooden structure and are filled with different minerals and gems including gold, emeralds, and illusive diamonds, among others, which you’ll need to match up to land a winning combination. The soundtrack is simple yet effective and adds to the theme of the game with a light and uplifting tune for you to whistle while you work.

Gem Miner RTP & Volatility 

Gem Miner is rated as a medium volatility slot and offers an RTP of 95.27%. Under the game information, there’s a handy key to let you know the probability of hitting each winning combination as well, so you can go into this slot fully informed of your winning chances. 

How to Play Gem Miner 

Whenever we sit down to play a new online slot, we always take some time to familiarise ourselves with the gameplay, rules, and controls for the game. A great way to do this is by playing free Expanse Studios slots right here at Slots Temple. 

In Gem Miner, all the controls are found beneath the reels as follows: 

1. To start, we always look for the game information in a new slot. For Gem Miner, you can access this info by looking for the ‘I’ icon in the bottom left-hand corner of the screen. 

2. Next to the ‘I’ icon, you’ll find the game settings (cog icon) and the ability to enter/leave full screen mode. 

3. When you’re happy with the game rules and settings, place your bet by using the ‘+’ and ‘-‘ buttons by the ‘Bet’ option towards the right-hand side of the control panel beneath the reels.

4. Once you’ve set your bet, click the large ‘Spin’ button on the far right-hand side to start playing. There’s no AutoSpin feature in this slot, so you’ll need to spin manually each time. 

5. You can keep an eye on your total balance and latest wins at the bottom of the screen. The paytable is also always viable to the left of the reels. 

Bet Sizes & Paytable 

Wagers start at just 1.00 per spin in Gem Miner and go all the way up to 1,000.00, which should make this game appealing to penny players and high rollers alike. 

As this is a simple 3x3 reel grid, the top prizes for each symbol are fixed and multiplied by your bet as follows: 

Carbon: x1

Amber: x5

Gold: x20

Emerald: x50

Amethyst: x200

Diamond: x1,000

The amount you’ll win for each symbol is calculated by multiplying the odds of hitting that winning combination of your wager. You can find details on this by clicking the ‘I’ icon in the bottom left-hand corner of the screen along with the probability percentages if you’re interested. 

Gem Miner Bonus Features 

Gem Miner doesn’t actually incorporate any bonus features in the gameplay and instead concentrates on providing a classic slot gaming experience with unique graphics and a fun theme. 

Conclusion 

In conclusion, although we generally prefer online video slots with loads of exciting bonus features and special effects, we were really impressed by Gem Miner. The simple gameplay made the game feel uncluttered and there was no ambiguity caused by symbols that may or may not trigger a feature so we could just concentrate on the excellent game. We really liked that Expanse added the probabilities of hitting each winning combination, as this meant we were able to spin the reels really confident that we knew the chances of winning . 

The graphics are particularly impressive in Gem Miner and we loved the unusual way the reels spin with the precious gems and minerals being revealed to us rather than just spinning on a standard grid (we also enjoyed the canary in the corner!). 

Jewel-themed slots are often popular with punters, probably because they show the riches we all hope to uncover when spinning! We have loads of other jewel themed slots here at Slots Temple for you to enjoy, completely free of charge, whenever and wherever the mood to spin takes you. 

If you enjoyed Gem Miner and fancy taking a spin on one of the other hundreds of slots we have for free play, then you might want to give Big Time Gaming’s Bonanza slot a try. This is an exciting Megaways slot with over 100,000 winning ways available, so there is loads of winning potential here!
