Three hilariously bearded Dwarves - Driler, Bombur, and Thundar - with amazing mining skills take you to their workplace and are willing to share their mining profits with you. Even though the reel action takes place in a dark mine deep underground, it’s obviously a light-hearted slot, offering 3 different bonus features and Free Spins with a Dwarven Gold train dropping Wilds all over the reels. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

Personal tester’s opinion about Mining Fever slot

Mining Fever slot machine is marvellous (quality-wise), exciting (feature-wise), and could be played for a long time (variance-wise). We had multiple super successful sessions (with both - free and real credits), where inside the base game without efforts and very swiftly, our balance grew by 45 % (above the initial amount). In the Free Spins, we gain an average of 60x the total bet, but our maximum was 225x the total bet, which is a very satisfactory performance for this low dispersion and short cycle 243 win ways slot.

  • In the base game, the probability of getting any hit is 29.23%. Despite the not so generous paytable, the numbers work out perfectly - making the gameplay fast, interesting, and profitable. Profitable, we say - for a low variance game, of course. That will say no epic wins, but 50x-60x the total bet in the main game is just very normal here.
  • The bonus round is launched quite often. Statistically, around every 80th spin (1.25%), one Free Spins round should be initiated, and 55% of the prize pool is reserved for payouts during them. These numbers confirm that you can receive one good reward from both: the usual and the Free Spins.

Altogether the dwarf features are diverse, keep you enticed in the main game, and sustain your balance for a long time. We recommend it to the bonus hunters. We also advise people on a limited budget to try their chances here, as the game can deliver frequent decent wins to those who prefer low-risk play with a modest payout.
