How to Play

When you start the game, you will get inside the mine where a round playing field is installed among the stones. Its reels rotate in opposite directions to produce wins within the 8 win areas. You need to click on the coins to select your bet level. The spin button will spin the 3 reels at the chosen bet level. The paytable provides the combos and payouts and all wins are multipliers. For example, any 3 of kind symbols paying 2x would pay 2 times the current bet level. Simultaneous wins on different win areas are added together.

To start digging all you need is:

  • Open Mining Machine at your favorite casino
  • Open the menu to read the rules
  • Choose a total bet: from €0.10 to €50
  • Spin the reels!

Mining Machine RTP and Volatility

8.5 

Low-medium volatility comes with 95% RTP.

The work of a gold digger is not easy, but in this slot, getting a large nugget will not seem too difficult for you, as it comes with low-medium volatility. This means that prize combinations on win areas are created here quite often. But we cannot say that the theoretical return is on your side, since it is 95%, which is 1% lower than the market average.

Theme

7.8 

This time, Concept Gaming decided to choose a frequently used, we would even say ‘mainstream’ theme of gold digging for their new slot machine. Unfortunately, the design of the game turned out to be not very outstanding either. All actions take place inside a dark mine, slightly lit in orange. On either side of the round iron playing field you will see stones and nothing else.

11 different nuggets with different values will appear on the ‘reels’ of the playing field and you also have a shovel - this is a special Bonus symbol 3 copies of which can activate the Bonus Round.

Overall Rating

7.5

Concept Gaming knows how to create high-quality games with cool concepts, but Mining Machine is hardly among them. All that this game can offer you is an unusual playing field.
The design looks really boring and most likely the provider was counting on you to be surprised with the round playing field that has win areas instead of lines but there is nothing ‘wow’ about it for experienced players. But if you are a low-risk newbie you might like this release and we can recommend it to you as there is really nothing wrong with it (except below the average RTP, of course).
